Finite-Temperature Density-Functional Theory of Bose-Einstein Condensates
Finite-Temperature Density-Functional Theory Bose-Einstein Condensates
font style='font-size:12px;'>
2010/11/25
The thermodynamic approach to density functional theory (DFT) is used to derive a versatile
theoretical framework for the treatment of finite–temperature (and in the limit, zero temperature)Bose–Eins...

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 ...

We propose a random matrix approach to describe vibrational excitations in disordered systems.
The dynamical matrix M is taken in the form M = AAT where A is some real (not generally
symmetric) rand...
Theory of Valley-Density Wave and Hidden Order in Iron-Pnictides
Theory of Valley-Density Wave Iron-Pnictides
font style='font-size:12px;'>
2010/11/19
In the limit of perfect nesting, the physics of iron-pnictides is governed by the density wave
formation at the zone-edge vector M. At high energies, various spin- (SDW), charge- (CDW),
orbital/pock...

2010/11/19
The density of states near zero energy in a graphene due to strong point defects with random
positions are computed. Instead of focusing on density of states directly, we analyze eigenfunctions of in...
