Self-congruent point in critical matrix product states: An effective field theory for finite-entanglement scaling
Jan T. Schneider, Atsushi Ueda, Yifan Liu +3
We set up an effective field theory formulation for the renormalization flow of matrix product states (MPS) with finite bond dimension, focusing on systems exhibiting finite-entang…
Pauli weight requirement of the matrix elements in time-evolved local operators: dependence beyond the equilibration temperature
Carlos Ramos-Marimón, Stefano Carignano, Luca Tagliacozzo
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 fo…
Measuring temporal entropies in experiments
Aleix Bou-Comas, Carlos Ramos Marimón, Jan T. Schneider +2
We propose a novel experimental protocol to measure generalized temporal entropies in many-body quantum systems. Our approach involves using local operators as probes to characteri…
Loschmidt echo, emerging dual unitarity and scaling of generalized temporal entropies after quenches to the critical point
Stefano Carignano, Luca Tagliacozzo
We show how the Loschmidt echo of a product state after a quench to a conformal invariant critical point and its leading finite time corrections can be predicted by using conformal…
