Universal Tomonaga-Luttinger liquid phases in one-dimensional strongly attractive SU(N) fermionic cold atoms
X. W. Guan, J. -Y. Lee, M. T. Batchelor +2
A simple set of algebraic equations is derived for the exact low-temperature thermodynamics of one-dimensional multi-component strongly attractive fermionic atoms with enlarged SU(…
Quantum Phases of Bose-Hubbard Model in Optical Superlattices
Bo-Lun Chen, Su-Peng Kou, Yunbo Zhang +1
In this paper, we analyze the quantum phases of multiple component Bose-Hubbard model in optical superlattices, using a mean-field method, the decoupling approximation. We find tha…
Superfluid to Bose-glass transition of hard core bosons in one-dimensional incommensurate optical lattice
Xiaoming Cai, Shu Chen, Yupeng Wang
We study superfluid to Anderson insulator transition of strongly repulsive Bose gas in a one dimensional incommensurate optical lattice. In the hard core limit, the Bose-Fermi mapp…
Transition from Tonks-Girardeau gas to super-Tonks-Girardeau gas as an exact many-body dynamics problem
Shu Chen, Liming Guan, Xiangguo Yin +2
We investigate transition of a one-dimensional interacting Bose gas from a strongly repulsive regime to a strongly attractive regime, where a stable highly excited state known as t…
Realization of effective super Tonks-Girardeau gases via strongly attractive one-dimensional Fermi gases
Shu Chen, Xi-Wen Guan, Xiangguo Yin +2
A significant feature of the one-dimensional super Tonks-Girardeau gas is its metastable gas-like state with a stronger Fermi-like pressure than for free fermions which prevents a…
D-wave bosonic pair in an optical lattice
Zi Cai, Lei Wang, Jian Li +3
We present a bosonic model, in which two bosons may form a bound pair with d-wave symmetry via the four-site ring exchange interaction. A d-wave pairing superfluid as well as a d-w…
Bose-Fermi mixture in one-dimensional optical lattices with hard-core interactions
Xiaoming Cai, Liming Guan, Shu Chen +2
We study a mixture of bosons with point hard-core boson-boson interactions and noninteracting spinless fermions with point hard-core boson-fermion interactions in 1…
Quantum Information Approach to Rotating Bose-Einstein Condensate
Zhao Liu, Hongli Guo, Shu Chen +1
We investigate the 2D weakly interacting Bose-Einstein condensate in a rotating trap by the tools of quantum information theory. The critical exponents of the ground state fidelity…
