Sub-linear radiation power dependence of photo-excited resistance oscillations in two-dimensional electron systems
Sub-linear radiation power dependence two-dimensional electron systems
2010/11/25
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...
Asymptotic analysis of stresses near a crack tip in a two dimensional colloidal packing saturated with liquid
Asymptotic analysis of stresses two dimensional colloidal
2010/11/24
The consolidation of colloidal particles in drying colloidal dispersions is in-uenced by various factors such as particle size and shape, and inter-particle potential. The capillary pressure induced b...
Lifshitz transition in two-dimensional spin-density wave models
Lifshitz transition two-dimensional spin-density wave models
2010/11/23
We argue that both pocket-disappearing and neck-disrupting types of Lifshitz transitions can be
realized in two-dimensional spin-density wave models for underdoped cuprates, and study both
types of ...
Polarons and Molecules in a Two-Dimensional Fermi Gas
Polarons Molecules Two-Dimensional Fermi Gas
2010/11/23
We study an impurity atom in a two-dimensional Fermi gas using variational wave functions for (i)an impurity dressed by particle-hole excitations (polaron) and (ii) a dimer consisting of the impurity ...
BCS-BEC crossover in a two-dimensional Fermi gas
BCS-BEC crossover two-dimensional Fermi gas
2010/11/23
We investigate the crossover from Bardeen-Cooper-Schrieffer (BCS) superfluidity to Bose-Einstein condensation (BEC) in a two-dimensional Fermi gas at T = 0 using the fixed-node diffusion Monte Carlo m...
Edge states in two-dimensional electron gas with heterogeneous spin-orbit interaction
Edge states two-dimensional electron gas heterogeneous spin-orbit interaction
2010/11/23
We show that edge states similar to those known for topological insulators exist in two-dimensional electron system with one-band spectrum in the presence of heterogeneous spin-orbit interaction (SOI)...
Coarsening Kinetics of a Two Dimensional O(2) Ginzburg-Landau Model: Effect of Reversible Mode Coupling
Coarsening Kinetics Two Dimensional O(2) Ginzburg-Landau Model
2010/11/25
We investigate, via numerical simulations, the phase ordering kinetics of a two-dimensional
soft-spin O(2) Ginzburg-Landau model when a reversible mode coupling is included via the
conserved conjuga...
Quasi-Two-Dimensional Fermi Surfaces and Coherent Interlayer Transport in KFe$_2$As$_2$
Quasi-Two-Dimensional Fermi Surfaces Coherent Interlayer Transport
2010/11/19
We report the results of the angular-dependent magnetoresistance oscillations (AMROs), which
can determine the shape of bulk Fermi surfaces in quasi-two-dimensional (Q2D) systems, in a highly hole-do...
U(1) $\times$ U(1) / Z$_2$ Kosterlitz-Thouless transition of the Larkin-Ovchinnikov phase in an anisotropic two-dimensional system
Kosterlitz-Thouless transition anisotropic two-dimensional system
2010/11/25
We study Kosterlitz-Thouless (KT) transitions of the Larkin-Ovchinnikov (LO) phase for a twodimensional system composed of coupled one-dimensional tubes of fermions. The LO phase here
is characterize...
Electron interaction-driven insulating ground state in Bi2Se3 topological insulators in the two dimensional limit
Electron interaction-driven two dimensional limit
2010/11/18
We report a transport study of ultrathin Bi2Se3 topological insulators with thickness from
one quintuple layer to six quintuple layers grown by molecular beam epitaxy. At low
temperatures, the film ...
Quantum Destruction of Spiral Order in Two Dimensional Frustrated Magnets
Quantum Destruction Spiral Order Two Dimensional Frustrated Magnets

We study the fate of S = 1/2 spiral ordered two dimensional quantum magnets when disordered
by quantum fluctuations. The topological point defects of the spiral, the Z2 vortices, play a crucial role ...
