Two-dimensional weakly interacting Bose gas in the fluctuation region
Two-dimensional bose gas range cross thermodynamics parameters superfluids
2014/12/22
We study the crossover between the mean-field and critical behavior of the two-dimensional Bose gas throughout the fluctuation region of the Berezinskii-Kosterlitz-Thouless phase transition point. We ...
Quantum-fluctuation effects in transport properties of superconductors above the paramagnetic limit
Quantum-fluctuation effects transport properties superconductors the paramagnetic limit
2012/2/27
We study the transport in ultrathin disordered film near the quantum critical point induced by the Zeeman field. We calculate corrections to the normal state conductivity due to quantum pairing fluctu...
