  • Benchmark of few-level quantum theory vs ab initio numerical solutions for
           the strong-field Autler–Townes effect in photoionization of hydrogen

    • Free pre-print version: Loading...

      Authors: D Younis; J H Eberly

      Abstract: The temporal and spectral consequences of an intermediate resonance en route to photoionization are investigated theoretically in two ways: by solving few-level model equations and by ab initio numerical solution of the time-dependent Schrödinger equation, in both cases for hydrogen in three dimensions. The model consists of atomic states resonantly field-dressed in a three-level reduction of the hydrogen atom that consists of the 2 p –3 d (Balmer) transition and one energetically-distant continuum state. The model's level occupation probabilities are derived from three Schrödinger amplitude equations and are benchmarked against an ab initio numerical solution for the hydrogen electron's wavefunction under the same field. We examine contrasts between the results of the two approaches with a particular focus on Autler–Townes doublets that appear in the photoelectron spectrum.

  • Effect of three-body interactions on Bénárd–von Kármán vortex street
           in quasi-2D Bose–Einstein condensate

      Authors: Xiaobei Fan; Xueping Ren, Jing Wang, Kaihua Shao, Qingqing Wang, Yuexing Zhao, Hongjuan Meng Yuren Shi

      Abstract: The dynamical behaviors of a quasi-2D Bose–Einstein condensate (BEC) with three-body interactions through a moving obstacle potential are studied numerically. Various vortex structures are discovered under different strength of three-body interactions when the two-body interaction is attractive or repulsive. When the width and moving velocity of the obstacle potential reach critical value, periodic anti-symmetric double-row vortex pairs will be released alternately in BEC, and a Bénárd–von Kármán (BvK) vortex street will be formed eventually. We noticed that the BvK vortex street can be excited when the three-body interactions are taken into account even if the two-body interaction is attractive. The mean value of the distance between two vortex rows to the distance between two vortex pairs in the same row is about 0.2. It is slightly smaller than the stability condition 0.28 without considering the three-body interaction. The parameter regions of vortex patterns at different three-body interaction are determined. It is found that an appropriate value of three-body interaction with larger velocity and lesser width is favorable to the formation of BvK vortex street. In a pair of point vortices, the distance and angular velocity between them are nearly invariant while they rotate around their center. The internal rule of vortex pair are also analyzed by calculating the drag force acting on the obstacle potential. Finally, we proposed an experimental protocol to realize the vortex street in 87 Rb BEC with three-body interactions.

           by generalized configuration interaction method

      Authors: V G Yarzhemsky; L V Chernysheva

      Abstract: Satellites i.e. two-hole-one-particle states appear due to many-electron correlations in photoelectron spectra in addition to main lines corresponding to one-hole states. The correct assignment of these states is important for understanding the photoionization processes and for materials analysis by photoelectron spectroscopy. In the present work two different existing methods, which use overlap or Coulomb interaction matrix elements are considered and a new method is proposed. In this technique many-electron effects of satellites origin and interactions between satellite states are accounted for simultaneously by solving secular matrix. The method is applied to satellite states 2 p −2 3 p (4 p ), 2 p −2 3 s , 2 p −2 3 d of Ne photoionization for which contradiction between two interpretations existed. The results of calculations unambiguously support one the interpretations.

  • HF, DF, TF: approximating potential curves, calculating rovibrational
           states

    • Free pre-print version: Loading...

      Authors: Laura E Angeles-Gantes; Horacio Olivares-Pilón
      First page: 165101
      Abstract: A simple analytical expression for the potential energy curve for the ground state X 1 Σ + of the hydrogen fluoride molecule HF obtained in the framework of the Born–Oppenheimer approximation is proposed. This analytical expression for the potential energy curve is based in the two point Padé approximation, which correctly reproduces the asymptotic behavior at small R → 0 and large R → ∞ internuclear distances, and position and depth of potential well, leading to the accuracy of 4–5 decimal digits when compared with experimental data. The rovibrational spectra of the diatomic molecule HF is calculated by solving the Schrödinger equation for nuclear motion using the Lagrange-mesh method. The ground state X 1 Σ + contains 21 vibrational states ( ν , 0) and 724 rovibrational states ( ν , L ) with maximal angular momentum equal to 55. The change of reduced mass in the Schrödinger equation for nuclear motion allows us to obtain the rovibrational spectrum of the ground state potential curve of the deuterium fluoride DF (contains 29 vibrational states ( ν , 0) and 1377 rovibrational states ( ν , L )) and tritium fluoride TF (contains 35 vibrational states ( ν , 0) and 1967 rovibrational states ( ν , L )) with maximal angular momenta 76 and 92, respectively. Entire rovibrational spectra is presented for the HF molecule and its two isotopologues DF and TF.

      Abstract: In the present work, a detailed study has been reported on electron impact elastic scattering from krypton (Kr) and xenon (Xe) atoms when confined in two different types of C 60 potentials viz (a) hard annular square well (ASW) and (b) diffused Gaussian annular square well (GASW). The Dirac equations are solved using these potentials for encaged Kr and Xe in C 60 . First, bound state Dirac–Fock wave functions of these encaged Kr and Xe atoms are found by utilizing modified general relativistic atomic structure package and thereafter, the charge densities and static potentials of the endohedral Kr@C 60 and Xe@C 60 are obtained. Further, using these, the Dirac equations are solved by the relativistic partial wave phase shift analysis method and the scattering amplitudes in terms of phase shifts are obtained. Thereafter, the electron elastic differential and integrated cross sections of Kr@C 60 and Xe@C 60 along with the C 60 are calculated in the range of 0.1–15 eV incident electron energies. Presently, no experimental and theoretical results are available to compare our electron scattering cross section results from Kr@C 60 and Xe@C 60 ; thus, we have shown the cross section results obtained from ASW and GASW potential and compared them.

      Authors: Nikita Dhankhar; Soham Banerjee R Choubisa

      Abstract: We present the angular profiles of the triple differential cross-section (TDCS) for the (e, 2e) process on the noble gas atoms, namely He (1s), Ne (2s and 2p), and Ar (3p), for the plane wave and the twisted electron impact. We develop the theoretical formalism in the first Born approximation (FBA). The present study compares the TDCS for different values of orbital angular momentum number m and opening angles θ p of the twisted electron beam with that of the plane wave beam in co-planar asymmetric geometry. In addition, we also investigate the TDCS for macroscopic targets to explore the influence of the opening angle θ p of the twisted electron beam on the TDCS. Our results show that the peaks in binary and recoil regions shift from the momentum transfer direction. The results also show that for larger opening angles, the peaks for p -type orbitals split into double-peak structures, which are not observed in the plane wave results for the given kinematics. The angular profiles for averaged cross-section show the dependence of TDCS on the opening angles, especially for the larger opening angles, which are significantly different from the plane wave TDCS.

      Authors: Huan Chen; Honghua Ma, Yanyan Ding, Qianguang Li Xunong Yi
      First page: 165401
      Abstract: In this work, the Imbert–Fedorov (IF) shift is systematically investigated when a light beam is incident on black phosphorus. Using the angular spectrum theory, we obtain the analytical expressions of IF shifts for a p -polarized and s -polarized beam. Based on the theoretical analysis, numerical calculations are performed. The results indicate that the IF shifts depend on the incident angle, polarization and frequency of incident light, as well as the optical axis angle and electron concentration of black phosphorus. These characteristics make it possible to accurately measure the physical parameters of two-dimensional atomic materials based on IF shifts.

           ground-state in the unresolved sideband regime

      Authors: Daryoosh Mansouri; Behrooz Rezaie, Abolfazl Ranjbar N Abolghasem Daeichian

      Abstract: This paper presents a cavity-assisted coherent feedback scheme to cool a mechanical resonator to the ground-state in a weak optomechanical coupling setup. Based on the theory of sideband cooling, resolved sideband regime is a mandatory condition for the ground-state cooling (GSC) in optomechanical systems. Assisted cooling and feedback cooling methods have been proposed and shown to be beneficial for cooling in unresolved sideband cases. In this paper, a cooling method is proposed by combining both approaches. In the proposed method, a coherent feedback loop is added to a cavity-assisted optomechanical system to enhance the cooling performance. The proposed feedback aims to reach the mechanical ground-state in the unresolved sideband regime (USR). Rate equations of the mechanical resonator are derived, and then, by applying Fermi's golden rule and analyzing the fluctuation spectrum of the optical force, optimal conditions for cooling are obtained. Results show that applying coherent feedback, improves the cooling performance of the system significantly and it is possible to achieve GSC in USR. Moreover, it is shown that the proposed method is capable of cooling the mechanical resonator to much lower energy levels than it is achievable in cavity assisted method.

  • Optical pumping and relaxation of atomic population in assorted conditions

      Authors: Saptarshi Roy Chowdhury; Swarupananda Pradhan
      First page: 165502
      Abstract: Precise control and knowledge over atomic dynamics is central to the advancement of quantum technology. The different experimental conditions namely, atoms in a vacuum, antirelaxation coated and buffer gas filled atomic cells provide complementary platforms for such investigations. The extent of changes in optical pumping, velocity changing collision and hyperfine changing collision rates associated with these conditions are discussed. There is a phenomenal change in the optical density by a factor of>25 times in the presence of a control field in a buffer gas environment. We found confinement induced enhanced optical pumping as the mechanism behind the observed transparency in buffer gas cell. The diffusive velocity of atoms were measured to be ∼25 ± 12 m s −1 and ⩽8 ± 4 m s −1 for antirelaxation coated and buffer gas filled cells respectively. The measurements were carried out for 85 Rb atoms in natural isotopic composition using pump–probe spectroscopy. The studies will have useful application in measurements of relaxation rates, quantum memory, quantum repeaters and atomic devices.

      Abstract: We investigate photoelectron holography in bichromatic linearly polarized fields of commensurate frequencies rω and sω , with emphasis on the existing symmetries and for which values of the relative phase between the two driving waves they are kept or broken. Using group-theoretical methods, we show that, additionally to the well-known half-cycle symmetry, which is broken for r + s odd, there are reflection symmetries around the field zero crossings and maxima, which may or may not be kept, depending on how both waves are dephased. The three symmetries are always present for monochromatic fields, while for bichromatic fields this is not guaranteed, even if r + s is even and the half-cycle symmetry is retained. Breaking the half-cycle symmetry automatically breaks one of the other two, while, if the half-cycle symmetry is retained, the other two symmetries are either both kept or broken. We analyze how these features affect the ionization times and saddle-point equations for different bichromatic fields. We also provide general expressions for the relative phases ϕ which retain specific symmetries. As an application, we compute photoelectron momentum distributions for ω − 2 ω fields with the Coulomb quantum orbit strong-field approximation and assess how holographic structures such as the fan, the spider and interference carpets behave, focusing on the reflection symmetries. The features encountered can be traced back to the field gradient and amplitude affecting ionization probabilities and quantum interference in different momentum regions.
