Magnetic Phase Transitions in One-dimensional Strongly Attractive Three-Component Ultracold Fermions

, 2008
We investigate the nature of trions, pairing and quantum phase transitions in one-dimensional strongly attractive three-component ultracold fermions in external fields.

An exactly solvable model of the BCS-BEC crossover

, 2004
We discuss an integrable model of interacting Fermions in one dimension, that allows an exact description of the crossover from a BCS- to a Bose-like superfluid. This model bridges the Gaudin-Yang model of attractive spin 1/2 Fermions to the Lieb-Liniger

Normal and Anomalous Averages for Systems with Bose-Einstein Condensate

, 2005
The comparative behaviour of normal and anomalous averages as functions of momentum or energy, at different temperatures, is analysed for systems with Bose-Einstein condensate.

Density-Matrix Renormalization Group Study of Trapped Imbalanced Fermi Condensates

, 2008
The density-matrix renormalization group is employed to investigate a harmonically-trapped imbalanced Fermi condensate based on a one-dimensional attractive Hubbard model.

Antimatter and the second law of thermodynamics

, 2018
In this letter we make a proposal that the second law of thermodynamics holds true for a closed physical system consisting of pure antimatter in the thermodynamical limit, but in a reversed form. We give two plausible arguments in favour to this proposal:

Magnetic field dependence and the possibility of filtering ultraslow light pulses in atomic gases with Bose-Einstein condensates

, 2010
This paper studies theoretically the ultraslow light phenomenon in Bose-Einstein condensates of alkali-metal atoms. The description is based on the linear approach that is developed in the framework of the Green function formalism. It is pointed out that

Quantitative comparison between theoretical predictions and experimental results for the BCS-BEC crossover

, 2004
Theoretical predictions for the BCS-BEC crossover of trapped Fermi atoms are compared with recent experimental results for the density profiles of $^6$Li.

Ground state energy of a homogeneous Bose-Einstein condensate beyond Bogoliubov

, 2004
The standard calculations of the ground-state energy of a homogeneous Bose gas rely on approximations which are physically reasonable but difficult to control. Lieb and Yngvason [Phys. Rev. Lett.
