Doped resonating-valence-bond states: Robustness of the spin-ice phases in three-dimensional Rydberg arrays
Jingya Wang, Changle Liu, Yan-Cheng Wang +1
Rydberg blockade effect provides a convenient platform for simulating locally constrained many-body systems, such as quantum dimer models and quantum loop models, especially their…
Exotic Superfluid with Emergent flux in a one-dimensional Bose-Fermi mixture
Qi Song, Jie Lou, Yan Chen
We find a novel chiral superfluid (CSF) phase in a one-dimensional Bose-Fermi Hubbard model with significant mass and density imbalance between the two species. In the CSF phase, b…
Ground-state phase diagram of two-component interacting bosons on a two-leg ladder
Po Chen, Chenrong Liu
Using the cluster Gutzwiller mean-field method, we numerically study the ground-state phase diagram of the non-hard-core two-component interacting bosons trapped in a two-leg ladde…
Pairing from repulsion in a two-dimensional Fermi gas with soft-core interactions
Ahmet Keles, Xiaopeng Li, Erhai Zhao
We investigate a model many-body system of spinless Fermi gas in two dimensions, where the bare two-body interaction is repulsive and takes the form of a soft-core disk potential.…
Ground state properties of a multi-component bosonic mixture: a Gutzwiller mean-field study
Chenrong Liu, Po Chen, Linli He +1
Using the single-site Gutzwiller method, we theoretically study the ground state and the interspecies entanglement properties of interexchange symmetric multi-component (two- and t…
Generalized effective-potential Landau theory for a tunable state-dependent hexagonal optical lattice
Sheng Yue, Dan-Yang Chen, Chenrong Liu +2
We analytically study the ground-state phase diagrams of ultracold bosons with various values of the effective magnetic quantum number in a state-dependent hexagonal optical la…
