Confinement-controlled pattern selection in a finite population-imbalanced dipolar Bose-Einstein condensate
Zhenhao Wang, Weijing Bao, Jia-Rui Luo +2
We study the ground-state density patterns of a population-imbalanced two-component dipolar Bose-Einstein condensate confined in a circular quasi-two-dimensional box. Using a mean-…
Polarization-controlled pattern formation in antiparallel dipolar binary condensates
Zhijun Zhang, Weijing Bao, Changjian Yu +3
We investigate non-equilibrium pattern formation in an antiparallel two-component dipolar Bose-Einstein condensate by varying the polarization angle and the trap aspect ratio. At f…
Local Non-Hermitian Hamiltonian Formalism for Dissipative Fermionic Systems and Loss-Induced Population Increase in Fermi Superfluids
Teng Xiao, Gentaro Watanabe
We examine a standard scheme to obtain the non-Hermitian Hamiltonian (NHH) from the Lindblad master equation by neglecting its jump term, and propose an alternative approach to add…
Universal relations and bounds for fluctuations in quasistatic small heat engines
Kosuke Ito, Guo-Hua Xu, Chao Jiang +4
The efficiency of any heat engine, defined as the ratio of average work output to heat input, is bounded by Carnot's celebrated result. However, this measure is insufficient to cha…
