Coherent tunneling of collective excitation of Bose-Einstein condensate in a double-well potential
Yaojun Ying, Haoyu Wang, Ming Zhang +1
The Josephson effect can be observed in a Bose-Einstein condensate in a double-well potential, which is attributed to the tunneling of bosons between two wells. We propose a multi-…
Identifying the closeness of eigenstates in quantum many-body systems
Haibin Li, Yang Yang, Pei Wang +1
We propose a new quantity called modulus fidelity to measure the closeness of two quantum pure states. Especially, we use it to investigate the closeness of eigenstates of quantum…
Momentum distribution functions in ensembles: the inequivalence of microcannonical and canonical ensembles in a finite ultracold system
Pei Wang, Gao Xianlong, Haibin Li
It is demonstrated that in many thermodynamic textbooks the equivalence of the different ensembles is achieved in the thermodynamic limit. In this present work we remark the inequi…
The origin of normal heat conduction in one-dimensional classics system
Haibin Li, Xiaotian Xin
We propose a new one-dimensional lattice model with strong asymmetric interaction potential and investigate heat conduction in this model numerically. We find that Fourier law is o…
The microscopic origin of thermodynamic entropy in isolated systems
J. M. Deutsch, Haibin Li, Auditya Sharma
A microscopic understanding of the thermodynamic entropy in quantum systems has been a mystery ever since the invention of quantum mechanics. In classical physics, this entropy is…
Entanglement in the scattering process by local impurity
Dong Yang, Shi-Jian Gu, Haibin Li
We study entanglement in the scattering processes by fixed impurity and Kondo impurity. The fixed impurity plays a role as spin state filter that is employed to concentrate entangl…
