How thermal is a filtered state?
Yilun Yang, J. Ignacio Cirac, Mari Carmen Bañuls
Quantum many-body states with sufficiently low energy variance can serve as approximations to thermal states, and they may be prepared by energy filtering simple pure states. In th…
Graph-theory measures capture weak ergodicity breaking on large quantum systems
Heiko Georg Menzler, Rafał Świętek, Mari Carmen Bañuls +1
We study the onset of weak ergodicity violations in closed quantum many-body systems and focus on cases in which they occur through a transition that is controlled by a model param…
Mesoscopic Regimes of Temporal Entanglement in Ergodic Quantum Systems
Sergio Cerezo-Roquebrún, Jan Thorben Schneider, Stefano Carignano +4
We study temporal correlations in interacting quantum systems through the influence functional of a half-infinite quantum Ising chain. Using Rényi entropies and temporal mutual inf…
Large deviations and conditioned monitored quantum systems: a tensor network approach
María Cea, Marcel Cech, Federico Carollo +2
Coexistence of different dynamical phases is a hallmark of glassy dynamics. This is well-studied in classical systems where the underlying theoretical framework is that of large de…
Excited states from local effective Hamiltonians of matrix product states and their entanglement spectrum transition
Denise Cocchiarella, Mingru Yang, Yueshui Zhang +3
Solving excited states is a challenging task for interacting systems. For one-dimensional critical systems, however, excited states can be directly accessed from the eigenvectors o…
Process Tensor Approaches to Non-Markovian Quantum Dynamics
Jonathan Keeling, E. Miles Stoudenmire, Mari-Carmen Bañuls +1
The paradigm of considering open quantum systems -- i.e. focusing only on the system of interest, and treating the rest of the world as an effective environment -- has proven to be…
