Control of dynamical phase transitions and non-ergodic relaxation via spinor phases
J. O. Austin-Harris, P. Sigdel, C. Binegar +3
Utilizing ultracold spinor gases as large-scale, many-body quantum simulation platforms, we establish a toolbox for the precise control, characterization, and detection of nonequil…
Integrability Breaking and Coherent Dynamics in Hermitian and Non-Hermitian Spin Chains with Long-Range Coupling
Y. S. Liu, X. Z. Zhang
Unraveling the mechanisms of ergodicity breaking in complex quantum systems is a central pursuit in nonequilibrium physics. In this work, we investigate a one-dimensional spin mode…
Lattice-enabled detection of spin-dependent three-body interactions
C. Binegar, J. O. Austin-Harris, S. E. Begg +3
We present the experimental detection of coherent three-body interactions, often masked by stronger two-body effects, through nonequilibrium spin dynamics induced by controllably q…
Relativistic configuration-interaction and coupled-cluster calculations of Ir transition energies and properties for optical clock applications
H. X. Liu, Y. M. Yu, B. B. Suo +2
The transition energies and properties of the Ir ion are calculated using the Kramers-restricted configuration-interaction (KRCI) and Fock-space coupled-cluster (FSCC) meth…
Landau-Zener-Stückelberg interference in edge state pumping
Y. Liu, Xiaoshui Lin, Ming Gong
The adiabatic edge state pumping (ESP) in one dimensional model, which has important applications in topological phase transition and quantum simulation, has been widely performed…
Observation of ergodicity breaking and quantum many-body scars in spinor gases
J. O. Austin-Harris, I. Rana, S. E. Begg +3
We experimentally and theoretically demonstrate spinor gases driven by spin-flopping fields are excellent platforms for investigating ergodicity breaking and quantum scarring. We o…
