Geometry and superfluidity of the flat band in a non-Hermitian optical lattice
Peng He, Hai-Tao Ding, Shi-Liang Zhu
We propose an ultracold-atom setting where a fermionic superfluidity with attractive s-wave interaction is uploaded in a non-Hermitian Lieb optical lattice. The existence of a real…
Nonlinear Bloch-Zener oscillations for Bose-Einstein condensates in a Lieb optical lattice
Peng He, Zhi Li
We investigate Bloch-Zener oscillations and mean-field Bloch bands of a Bose-Einstein condensate (BEC) in a Lieb optical lattice. We find that the atomic interaction will break the…
Universal low energy physics in one-dimensional multicompnent Fermi gases with a strongly repulsive -function interaction
Yuzhu Jiang, Peng He, Xi-Wen Guan
It was shown [Chin. Phys. Lett. 28, 020503 (2011)] that at zero temperature the ground state of the one-dimensional (1D) -component Fermi gas coincides with that of the spinless…
Quantum Criticality of one-dimensional multicomponent Fermi Gas with Strongly Attractive Interaction
Peng He, Yuzhu Jiang, Xiwen Guan +1
Quantum criticality of strongly attractive Fermi gas with symmetry in one dimension is studied via the thermodynamic Bethe ansatz (TBA) equations.The phase transitions driv…
Thermodynamics and spin-charge separation of one-dimensional strongly repulsive three-component fermions
Peng He, Jen Yee Lee, Xiwen Guan +2
The low temperature thermodynamics of one-dimensional strongly repulsive SU(3) fermions in the presence of a magnetic field is investigated via the Yang-Yang thermodynamic Bethe an…
Analytical thermodynamics of a strongly attractive three-component Fermi gas in one dimension
Peng He, Xiangguo Yin, Xiwen Guan +2
Ultracold three-component atomic Fermi gases in one dimension are expected to exhibit rich physics due to the presence of trions and different pairing states. Quantum phase transit…
