Chiral f-wave Topological Superuid in Triangular Optical Lattices
Ningning Hao, Guocai Liu, Ning Wu +2
We demonstrate that an exotically chiral f-wave topological superfluid can be induced in coldfermionic-atom triangular optical lattices through the laser-field-generated effective…
Quantum dynamics of hard-core bosons in tilted bichromatic optical lattices
Xiaoming Cai, Shu Chen, Yupeng Wang
We study the dynamics of strongly repulsive Bose gas in tilted or driven bichromatic optical lattices. Using the Bose-Fermi mapping and exact numerical method, we calculate the red…
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…
Quantum magnetism of ultra-cold fermion systems with the symplectic symmetry
Hsiang-hsuan Hung, Yupeng Wang, Congjun Wu
We numerically study quantum magnetism of ultra-cold alkali and alkaline-earth fermion systems with large hyperfine spin , which are characterized by a generic symme…
Quantum criticality in disordered bosonic optical lattices
Xiaoming Cai, Shu Chen, Yupeng Wang
Using the exact Bose-Fermi mapping, we study universal properties of ground-state density distributions and finite-temperature quantum critical behavior of one-dimensional hard-cor…
Stable Fulde-Ferrell-Larkin-Ovchinnikov pairing states in 2D and 3D optical lattices
Zi Cai, Yupeng Wang, Congjun Wu
We present the study of the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) pairing states in the -orbital bands in both two and three-dimensional optical lattices. Due to the quasi one…
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…
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…
Interaction-induced anomalous transport behavior in one dimensional optical lattice
Zi Cai, Lei Wang, X. C. Xie +1
The non-equilibrium dynamics of spin impurity atoms in a strongly interacting one-dimensional (1D) Bose gas under the gravity field is studied. We show that due to the non-equilibr…
Resonance Scattering in Optical Lattices and Molecules: Interband versus Intraband Effects
Xiaoling Cui, Yupeng Wang, Fei Zhou
We study the low-energy two-body scattering in optical lattices with all higher-band effects included in an effective potential, using a renormalization group approach. As the pote…
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…
Polarized Fermi gases in asymmetric optical lattices
Xiaoling Cui, Yupeng Wang
The zero-temperature phase diagrams of imbalanced two-species Fermi gases are investigated in asymmetric optical lattices with arbitrary potential depths, based on the exact spectr…
Phase diagram of imbalanced fermions in optical lattices
Xiaoling Cui, Yupeng Wang
The zero-temperature phase diagrams of imbalanced fermions in 3D optical lattices are investigated to evaluate the validity of the Fermi-Hubbard model. It is found that depending o…
