Universal scaling framework for parameterized quantum evolutions at criticality
Jan T. Schneider, Cristian Tabares, Alejandro González-Tudela +1
Variational ansätze are a cornerstone of quantum many-body physics, providing compact approximations to complex ground states using finite resources. Recent quantum-technology adva…
Extracting conformal data from Loschmidt echoes after critical quenches
Aleix Bou-Comas, Stefano Carignano, Sergio Cerezo-Roquebrún +2
Conformal field theory provides universal predictions for Loschmidt amplitudes following quenches from product states to critical Hamiltonians. Building on this observation, we dev…
Mapping twist fields to local operators via tensor networks
Andrea Bulgarelli, Marco Panero, Paolo Stornati +1
Twist fields are a powerful formal tool to compute Rényi entropies in quantum many-body systems, but their conventional formulation in tensor network states involves operations act…
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…
Interface roughening in the 3-D Ising model with tensor networks
Atsushi Ueda, Lander Burgelman, Luca Tagliacozzo +1
Interfaces in three-dimensional many-body systems can exhibit rich phenomena beyond the corresponding bulk properties. In particular, they can fluctuate and give rise to massless l…
