Temporal Complexity Hierarchies in Solvable Quantum Many-Body Dynamics
He-Ran Wang, Ilya Vilkoviskiy, Dmitry A. Abanin
The influence matrix (IM) provides a powerful framework for characterizing nonequilibrium quantum many-body dynamics by encoding multitime correlations into tensor-network states.…

Dynamical multipartite entanglement in a generalized Tavis-Cummings model with XY spin interaction
Yuguo Su, Zhijie Sun, Yiying Yan +5
Multipartite entanglement is a long-term pursuit in the resource theory, offering a potential resource for quantum metrology. Here, we present the dynamical multipartite entangleme…

Generalized Spin Helix States as Quantum Many-Body Scars in Partially Integrable Models
He-Ran Wang, Dong Yuan
Quantum many-body scars are highly excited eigenstates of non-integrable Hamiltonians which violate the eigenstate thermalization hypothesis and are embedded in a sea of thermal ei…
