Sub-linear radiation power dependence of photo-excited resistance oscillations in two-dimensional electron systems
Sub-linear radiation power dependence two-dimensional electron systems
font style='font-size:12px;'>

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...

2010/11/25
Homogeneous populations of oscillators have recently been shown to exhibit stable coexistence
of coherent and incoherent regions. Generalizing the concept of chimera states to the context of order-di...

2010/11/25
We present full atomistic calculations of the spin-flip time (T1) of electrons and holes mediated by acoustic phonons in self-assembled In1−xGaxAs/GaAs quantum dots at zero magnetic field. At lo...
An One Dimensional Adiabatic Model for Fusion Involving Loosely Bound and Halo Nuclei with Heavy Targets
One Dimensional Adiabatic Model Fusion Involving Loosely Bound Halo Nuclei Heavy Targets
font style='font-size:12px;'>
2011/1/7
An one dimensional adiabatic model has been proposed for fusion of loosely bound and halo light
nuclei with various heavy targets. It is shown that fusion cross sections at near and sub-barrier energ...

Recently, level crossings in the energy bands of crystals have been identified as a key signature for topological phase transitions. In general, three independent parameters must be tuned appropriatel...
Spin canting as a result of the competition between stripes and spirals in cuprates
Spin canting spirals in cuprates
font style='font-size:12px;'>
2010/11/24
Based on the extended Hubbard model we calculate the energy of stripe and spiral ground states.
We find that uniform spirals get favored by a large t′/t ratio but are unstable at small doping towards...

We investigate the constraints on the superfluid fraction of an amorphous solid following from
an upper bound derived by Leggett. In order to accomplish this, we use as input density profiles generat...

The Bardeen-Cooper-Schrieffer to Bose-Einstein condensate (BCS to BEC) crossover problem is
solved for stationary grey solitons via the Boguliubov-de Gennes equations at zero temperature.
These cros...

Lifshitz transition in two-dimensional spin-density wave models
Lifshitz transition two-dimensional spin-density wave models
font style='font-size:12px;'>
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 ...
