Double-exchange ferromagnetism of fermionic atoms in a -orbital hexagonal lattice
Haoran Sun, Erhai Zhao, Youjin Deng +1
A large class of correlated quantum materials feature strong Hund's coupling. Yet cold-atom quantum simulators have so far focused primarily on single-orbital Fermi-Hubbard systems…
Broad Feshbach resonance with a large background scattering length in a fermionic atom-molecule mixture
Zhen Su, Tong-Hui Shou, Huan Yang +6
We report the observation of a broad magnetic Feshbach resonance with a large background scattering length in an ultracold fermionic mixture of NaK molecules and $^{4…
Measuring Non-Hermitian Topological Invariants Directly from Quench Dynamics
Xiao-Dong Lin, Long Zhang
While non-Hermitian (NH) topological phases and phenomena have been observed across various quantum systems, directly measuring NH topological invariants remains a significant chal…
Quantum Simulation with Gauge Fixing: from Ising Lattice Gauge Theory to Dynamical Flux Model
Junsen Wang, Xiangxiang Sun, Wei Zheng
Quantum simulation of synthetic dynamic gauge field has attracted much attentions in recent years. There are two traditional ways to simulate gauge theories. One is to directly sim…
Partial confinement in a quantum-link simulator
Zheng Tang, Fei Zhu, Yi-Fan Luo +2
Confinement/deconfinement, captivating attributes of high-energy elementary particles, have recently garnered wide attention in quantum simulations based on cold atoms. Yet, the pa…
Observation of counterflow superfluidity in a two-component Mott insulator
Yong-Guang Zheng, An Luo, Ying-Chao Shen +8
The counterflow superfluidity (CSF) was predicted two decades ago. Counterintuitively, while both components in the CSF have fluidity, their correlated counterflow currents cancel…
