Entanglement correction due to local interactions in many-body systems
Yevheniia Cheipesh, Lorenzo Cevolani, Stefan Kehrein
The correction to the area law for the bipartite min-entanglement entropy of weakly and locally interacting fermions is calculated based on a perturbative extension of the flow equ…
Suppression of the horizon effect in pairing correlation functions of - chains after a quantum quench
A. D. Kühn, L. Cevolani, S. R. Manmana
We investigate the time evolution of density, spin, and pairing correlation functions in one-dimensional - models following a quantum quench using the time-dependent density…
Exact description of the boundary theory of the Kitaev Toric Code with open boundary conditions
Yevheniia Cheipesh, Lorenzo Cevolani, Stefan Kehrein
In this work we consider the Kitaev Toric Code with specific open boundary conditions. Such a physical system has a highly degenerate ground state determined by the degrees of free…
Analysis of the buildup of spatiotemporal correlations and their bounds outside of the light cone
Nils O. Abeling, Lorenzo Cevolani, Stefan Kehrein
In non-relativistic quantum theories the Lieb-Robinson bound defines an effective light cone with exponentially small tails outside of it. In this work we use it to derive a bound…
Universal Scaling Laws for Correlation Spreading in Quantum Systems with Short- and Long-Range Interactions
Lorenzo Cevolani, Julien Despres, Giuseppe Carleo +2
We study the spreading of information in a wide class of quantum systems, with variable-range interactions. We show that, after a quench, it generally features a double structure,…
Unitary dynamics of strongly-interacting Bose gases with time-dependent variational Monte Carlo in continuous space
Giuseppe Carleo, Lorenzo Cevolani, Laurent Sanchez-Palencia +1
We introduce time-dependent variational Monte Carlo for continuous-space Bose gases. Our approach is based on the systematic expansion of the many-body wave-function in terms of mu…
Spreading of correlations in exactly-solvable quantum models with long-range interactions in arbitrary dimensions
Lorenzo Cevolani, Giuseppe Carleo, Laurent Sanchez-Palencia
We study the out-of-equilibrium dynamics induced by quantum quenches in quadratic Hamiltonians featuring both short- and long-range interactions. The spreading of correlations in t…
Unusual Corrections to the Scaling of the Entanglement Entropy of the Excited states in Conformal Field Theory
Lorenzo Cevolani
In this paper we study the scaling of the correction of the Renyi entropy of the excited states in systems described, in the continuum limit, by a conformal field theory (CFT). The…
Protected quasi-locality in quantum systems with long-range interactions
Lorenzo Cevolani, Giuseppe Carleo, Laurent Sanchez-Palencia
We study the out-of-equilibrium dynamics of quantum systems with long-range interactions. Two different models describing, respectively, interacting lattice bosons and spins are co…
