Sub-linear radiation power dependence of photo-excited resistance oscillations in two-dimensional electron systems
Sub-linear radiation power dependence two-dimensional electron systems

We find that the amplitude of the Rxx radiation-induced magnetoresistance oscillations in
GaAs/AlGaAs system grows nonlinearly as A / P where A is the amplitude and the exponent
< 1. This strikin...
Large bulk resistivity and surface quantum oscillations in the topological insulator Bi2Te2Se
Large bulk resistivity surface quantum oscillations
2010/11/22
Topological insulators are predicted to present novel surface transport phenomena, but their
experimental studies have been hindered by a metallic bulk conduction that overwhelms the surface transpor...
Anomalous Bloch oscillations in one dimensional parity-breaking periodic potentials
Anomalous Bloch oscillations dimensional parity-breaking periodic potentials

We investigate the dynamics of a wave packet in a parity-breaking one-dimensional periodic
potential slowly varied in time and perturbed by a linear potential. Parity is broken by considering an asym...
First Observation of Quantum Oscillations in the Ferromagnetic Superconductor UCoGe
Quantum Oscillations Ferromagnetic Superconductor UCoGe

We succeeded in growing high quality single crystals of the ferromagnetic superconductor
UCoGe and measured the magnetoresistance at fields up to 34T. The Shubnikov-de Haas
signal was observed for t...

We extend a general-relativistic ideal magneto-hydrodynamical code to include the effects of elasticity. Using this numerical tool we analyse the magneto-elastic oscillations of highly magnetised neut...
Nonequilibrium free energy, H theorem and self-sustained oscillations for Boltzmann-BGK descriptions of semiconductor superlattices
Nonequilibrium processes Boltzmann equation current fluctuations

Semiconductor superlattices (SL) may be described by a Boltzmann-Poisson kinetic equation with a Bhatnagar-Gross-Krook (BGK) collision term which preserves charge, but not momentum or energy.
Triggering collective oscillations by three-flavor effects
collective oscillations three-flavor effects
2010/3/15
Collective flavor transformations in supernovae, caused by neutrino-neutrino interactions, are essentially a two-flavor phenomenon driven by the atmospheric mass difference and the small mixing angle ...
