Exceptionally Slow Relaxation from Micro-canonical to Canonical Ensembles in Quasi-one-dimensional Quantum Gases
Huaichuan Wang, Xixiang Du, Zhongchi Zhang +8
Integrability in one dimension prevents quantum thermalization and gives rise to rich many-body phenomena described by generalized hydrodynamics, which have been extensively studie…
Dissipation Driven Coherent Dynamics Observed in Bose-Einstein Condensates
Ye Tian, Yajuan Zhao, Yue Wu +10
We report the first experimental observation of dissipation-driven coherent quantum many-body oscillation, and this oscillation is manifested as the coherent exchange of atoms betw…
Creation of 2000-atom Greenberger-Horne-Zeilinger states by entanglement amplification
Yajuan Zhao, Rui Zhang, Wenlan Chen +2
We propose a novel entanglement-creation scheme in a multi-atom ensemble, named entanglement amplification, which converts unentangled states into entangled states and amplifies le…
Vacuum spin squeezing
Jiazhong Hu, Wenlan Chen, Zachary Vendeiro +3
We investigate the generation of entanglement (spin squeezing) in an optical-transition atomic clock through the coupling to a vacuum electromagnetic field that is enhanced by an o…
Strictly nonclassical behavior of a mesoscopic system
Jiazhong Hu, Zachary Vendeiro, Wenlan Chen +4
We experimentally demonstrate the strictly nonclassical behavior in a many-atom system using a recently derived criterion [E. Kot et al., Phys. Rev. Lett. 108, 233601 (2012)] that…
Entangled collective-spin states of atomic ensembles under non-uniform atom-light interaction
Jiazhong Hu, Wenlan Chen, Zachary Vendeiro +2
We consider the optical generation and verification of entanglement in atomic ensembles under non-uniform interaction between the ensemble and an optical mode. We show that for a w…
Entanglement with Negative Wigner Function of Three Thousand Atoms Heralded by One Photon
Robert McConnell, Hao Zhang, Jiazhong Hu +2
Quantum-mechanically correlated (entangled) states of many particles are of interest in quantum information, quantum computing and quantum metrology. Metrologically useful entangle…
Carving complex many-atom entangled states by single-photon detection
Wenlan Chen, Jiazhong Hu, Yiheng Duan +3
We propose a versatile and efficient method to generate a broad class of complex entangled states of many atoms via the detection of a single photon. For an atomic ensemble contain…
Generating Entangled Spin States for Quantum Metrology by Single-Photon Detection
Robert McConnell, Hao Zhang, Senka Ćuk +3
We propose and analyze a probabilistic but heralded scheme to generate pure, entangled, non-Gaussian states of collective spin in large atomic ensembles by means of single-photon d…
