Continuous Bose-Einstein condensation
Chun-Chia Chen, Rodrigo González Escudero, Jiří Minář +3
Bose-Einstein condensates (BECs) are macroscopic coherent matter waves that have revolutionized quantum science and atomic physics. They are essential to quantum simulation and sen…
Criticality-enhanced quantum sensing in ferromagnetic Bose-Einstein condensates: role of readout measurement and detection noise
Safoura S. Mirkhalaf, Daniel Benedicto Orenes, Morgan W. Mitchell +1
We theoretically investigate estimation of the control parameter in a ferromagnetic Bose-Einstein condensate near second order quantum phase transitions. We quantify sensitivity by…
Droplet under confinement: Competition and coexistence with soliton bound state
Xiaoling Cui, Yinfeng Ma
We study the stability of quantum droplet and its associated phase transitions in ultracold Bose-Bose mixtures uniformly confined in quasi-two-dimension. We show that the confineme…
Quantum Simulation of Lattice Gauge Theories on Superconducting Circuits: Quantum Phase Transition and Quench Dynamics
Zi-Yong Ge, Rui-Zhen Huang, Zi Yang Meng +1
Recently, quantum simulation of low-dimensional lattice gauge theories (LGTs) has attracted many interests, which may improve our understanding of strongly correlated quantum many-…
Numerically exact mimicking of quantum gas microscopy for interacting lattice fermions
Stephan Humeniuk, Yuan Wan
A numerical method is presented for reproducing fermionic quantum gas microscope experiments in equilibrium. By employing nested componentwise direct sampling of fermion pseudo-den…
Open Fermi-Hubbard model: Landauer's vs. master equation approaches
A. R. Kolovsky
We introduce a simple model for the quantum transport of Fermi particles between two contacts connected by a lead. It generalizes the Landauer formalizm by explicitly taken into ac…
