Pauli weight requirement of the matrix elements in time-evolved local operators: Dependence beyond the equilibration temperature

Marcelo Castellanos2025-04-29T11:13:15+02:00Tags: Applied; Physics, Condensed Matter. , Materials Science, Multidisciplinary; Physics|

Authors: Ramos-Marimon, Carlos; Carignano, Stefano; Tagliacozzo, Luca Journal: PHYSICAL REVIEW B Publication date: 2025/03/05 DOI: 10.1103/PhysRevB.111.094301 Abstract: The complexity of simulating the out-of-equilibrium evolution of local operators in the Heisenberg picture is governed by the operator entanglement, which grows linearly in time for generic nonintegrable systems, leading to an exponential increase in computational resources. A [...]
