Grand-canonical phase diagram and chiral-current suppression at flux in a bosonic two-leg ladder
Meng Zhang, Qingyun Xu, Zhi Lin
We investigate the ground-state phase diagram of repulsively interacting bosons on a two-leg ladder threaded by a uniform artificial magnetic flux, using the cluster Gutzwiller mea…
Resonance fluorescence of an artificial atom with a time-delayed coherent feedback
Ching-Yeh Chen, Gavin Crowder, Zheng-Qi Niu +7
The model of light-matter interaction in quantum electrodynamics typically relies on the Markovian approximation, which assumes that the system's future evolution depends solely on…
Floquet-Engineered Hybrid Topological Orders with Majorana Edge Modes in Number-Conserving Fermionic Quantum Simulators
Zhi Lin, Qi Song, Sheng Yue +3
We develop an experimental protocol based on Floquet-engineered ultracold fermions in optical lattices, enabling the emulation of pair-hopping and competing singlet/triplet pairing…
Delta-Learning approach combined with the cluster Gutzwiller approximation for strongly correlated bosonic systems
Zhi Lin, Tong Wang, Sheng Yue
The cluster Gutzwiller method is widely used to study the strongly correlated bosonic systems, owing to its ability to provide a more precise description of quantum fluctuations. H…
