Tuning interaction strength leads to ergodic-nonergodic transition of quantum correlations in anisotropic Heisenberg spin model

Utkarsh Mishra, R. Prabhu, Aditi Sen De +1

We investigate the time dynamics of quantum correlations of the anisotropic Heisenberg model in a time-dependent magnetic field, in one-dimensional, ladder, and two-dimensional lat…

Limit on Time-Energy Uncertainty with Multipartite Entanglement

Manabendra Nath Bera, R. Prabhu, Arun Kumar Pati +2

We establish a relation between the geometric time-energy uncertainty and multipartite entanglement. In particular, we show that the time-energy uncertainty relation is bounded bel…
