quasiequilibrium supersolid phase of a two dimensional dipolar crystal
Physical Review B, 2010Co-Authors: I L Kurbakov, Yu E Lozovik, G E Astrakharchik, J BoronatAbstract:We have studied the possible existence of a supersolid phase of a two-dimensional dipolar crystal using quantum Monte Carlo methods at zero temperature. Our results show that the commensurate solid is not a supersolid in the thermodynamic limit. The presence of vacancies or interstitials turns the solid into a supersolid phase even when a tiny fraction of them are present in a Macroscopic System. The effective interaction between vacancies is repulsive making a quasiequilibrium dipolar supersolid possible.

Joule–Thomson Coefficient for Strongly Interacting Unitary Fermi Gas
Communications in Theoretical Physics, 2010Co-Authors: Chen Mo-sheng, Li ChaoAbstract:The Joule–Thomson effect reflects the interaction among constituent particles of Macroscopic System. For classical ideal gas, the corresponding Joule–Thomson coefficient is vanishing while it is non-zero for ideal quantum gas due to the quantum degeneracy. In recent years, much attention is paid to the unitary Fermi gas with infinite two-body scattering length. According to universal analysis, the thermodynamical law of unitary Fermi gas is similar to that of non-interacting ideal gas, which can be explored by the virial theorem P = 2E/3V. Based on previous works, we further study the unitary Fermi gas properties. The effective chemical potential is introduced to characterize the nonlinear levels crossing effects in a strongly interacting medium. The changing behavior of the rescaled Joule–Thomson coefficient according to temperature manifests a quite different behavior from that for ideal Fermi gas.
