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…
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…
