Electrophoretic Retardation of Colloidal Particles in Nonpolar Liquids
- Authors: Filip Strubbe; Filip Beunis, Toon Brans, Masoumeh Karvar, Wouter Woestenborghs, Kristiaan Neyts
  First page: 021001
  Abstract: Author(s): Filip Strubbe, Filip Beunis, Toon Brans, Masoumeh Karvar, Wouter Woestenborghs, and Kristiaan NeytsThe fundamental principle for electrophoresis, the motion of a charged particle in solution driven by an applied electric field, is well understood. But experimental measurements of the electrophoretic retardation force, one of those responsible for electrophoresis, have been scarce and equivocal. Now a Belgian group develops a creative new approach to control the source of the retardation—the counterion cloud surrounding the charged particle—by gradual depletion and makes unambiguous measurement of the retardation force.

Interacting Turing-Hopf Instabilities Drive Symmetry-Breaking Transitions in a Mean-Field Model of the Cortex: A Mechanism for the Slow Oscillation
- Authors: Moira L. Steyn-Ross; D. A. Steyn-Ross, J. W. Sleigh
  First page: 021005
  Abstract: Author(s): Moira L. Steyn-Ross, D. A. Steyn-Ross, and J. W. SleighSlow oscillations in neuronal activity in the human brain are the defining feature of scalp-measured electroencephalography taken under general anesthesia. A theoretical investigation of a model for the human cortex reveals that slow spatiotemporal patterns emerge spontaneously as the result of a chemically modified balancing act between two instabilities in cortical dynamics—one to spatial organizations and the other to temporal bifurcation. Long-range interneuronal communication across the cortex is shown to be crucial to the pattern formation. [Phys. Rev. X 3, 021005] Published Thu May 09, 2013

Stochastic Model for the Vocabulary Growth in Natural Languages
- Authors: Martin Gerlach; Eduardo G. Altmann
  First page: 021006
  Abstract: Author(s): Martin Gerlach and Eduardo G. AltmannWhat cultural and social processes determine the size and growth of the vocabulary of a natural language? Does such a vocabulary grow forever? From large text databases, such as the Google Ngram, that have become available only recently, researchers tease out new and systematic insights into these fundamental questions and develop a mathematical model with predictive power that describes vocabulary growth as a simple stochastic process.

  Abstract: Author(s): Jeroen B. Oostinga, Luis Maier, Peter Schüffelgen, Daniel Knott, Christopher Ames, Christoph Brüne, Grigory Tkachov, Hartmut Buhmann, and Laurens W. MolenkampWhile the tracks of the elusive Majorana fermion have been seen in semiconductor nanowires in contact with superconductors, this exotic particle is also predicted to appear in nanostructures made of three-dimensional topological insulators, such as HgTe, with induced superconducting surface current. Researchers show that such supercurrent can indeed be induced in HgTe Josephson junctions and offer insights into the underlying mechanism. [Phys. Rev. X 3, 021007] Published Tue May 28, 2013

HuardIn sensing-feedback control of a quantum system, optimizing the timing of the sensing measurements turns out to be a key to getting around the fundamental difficulty that a measurement can randomly change the system’s state. Achieving optimal timing by combining technical advances with conceptual physical insight, researchers demonstrate, for the first time, high-fidelity control of a superconducting qubit along time-dependent trajectories.

Protected Edge Modes without Symmetry

  Abstract: Author(s): Michael LevinSo far two mechanisms, time-reversal symmetry and chirality, have been known to “protect” conducting edge states in a bulk insulator. Now Michael Levin of University of Maryland reveals “fractional statistics” of bulk particle-like excitations as the third (and final) mechanism of edge-state protection in two-dimensional insulators.

Using a series of experiments that compare the electrical properties of amorphous and crystalline LaAlO3/SrTiO3 heterostructures, researchers discover that the answer depends on the structure of the LaAlO3 overlayer.

To achieve a quantum standard of current based on electron counting, an extremely accurate electron pump with a high current yield in the nanoampere range is required. Researchers now present a proof-of-principle demonstration of such a pump. [Phys. Rev. X 3, 021012] Published Thu May 30, 2013

  Abstract: Author(s): N. Q. Vinh, B. Redlich, A. F. G. van der Meer, C. R. Pidgeon, P. T. Greenland, S. A. Lynch, G. Aeppli, and B. N. MurdinSpectroscopic studies of the relaxation dynamics of excited single “acceptor” impurities in silicon, such as boron or aluminum, show that these impurities both have the potential to work as “qubits” and can also enrich trapped-atom experiments in solids.

Feng (封东来)New experimental findings about the electronic structure of NaFe0.9825Co0.0175As explain the fundamentally intriguing and important puzzle of why magnetic order and superconductivity can coexist in such iron-based superconductors and reveal an intimate tie between the coexistence and the electron pairing underlying the superconductivity.

Bogorin, Feng Bi, Mengchen Huang, Shicheng Lu, Chung-Wung Bark, Sangwoo Ryu, Kwang-Hwan Cho, Chang-Beom Eom, and Jeremy LevyThe LaAlO3/SrTiO3 interface is already known to have interesting properties such as superconductivity and magnetism. Now nanoscale charge-transport networks created at the interface show extraordinary evidences of violation of Ohm’s law. [Phys. Rev. X 3, 011021] Published Tue Mar 26, 2013
