Critical Temperature Shift in Weakly Interacting Bose Gas
High performance monte carlo quantum bose gas the scattering
2014/12/22
With a high-performance Monte Carlo algorithm we study the interaction-induced shift of the critical point in weakly interacting three-dimensional |ψ|4 theory (which includes quantum Bose gas). In ter...
Critical Temperature and Thermodynamics of Attractive Fermions at Unitarity
Dilution system lattice fermion monte carlo thermodynamic functions
2014/12/20
The unitarity regime of the BCS-BEC crossover can be realized by diluting a system of two-component lattice fermions with an on-site attractive interaction. We perform a systematic-error-free finite-t...
Critical Temperature of Interacting Bose Gases in Two and Three Dimensions
Superfluid temperature bose gas the space dimension integral monte carlo simulation particles atoms
2014/12/19
We calculate the superfluid transition temperature of homogeneous interacting Bose gases in three and two spatial dimensions using large-scale path integral Monte Carlo simulations (with up to N=105 p...
Critical Temperature Curve in BEC-BCS Crossover
Strong relevant regime condensation two-component system fermion monte carlo method function
2014/12/19
The strongly correlated regime of the crossover from Bardeen-Cooper-Schrieffer pairing to Bose-Einstein condensation can be realized by diluting a system of two-component fermions with a short-range a...
Suppression of the critical temperature for superfluidity near the Mott transition
Ultracold atoms optical lattice gas. Quantum multibody system such as quantum simulator
2014/12/19
Ultracold atomic gases in optical lattices have proven to be a controllable, tunable and clean implementation of strongly interacting quantum many-body systems. An essential prospect for such quantum ...
