Domain wall melting across a defect
Luca Capizzi, Stefano Scopa, Federico Rottoli +1
We study the melting of a domain wall in a free-fermionic chain with a localised impurity. We find that the defect enhances quantum correlations in such a way that even the smalles…
Entanglement evolution after a global quench across a conformal defect
Luca Capizzi, Viktor Eisler
We study the evolution of entanglement after a global quench in a one-dimensional quantum system with a localized impurity. For systems described by a conformal field theory, the e…
Rényi entropy and negativity for massless complex boson at conformal interfaces and junctions
Luca Capizzi, Sara Murciano, Pasquale Calabrese
We consider the ground state of a theory composed by species of massless complex bosons in one dimension coupled together via a conformal interface. We compute both the Rényi e…
Symmetry Resolved Entanglement of Excited States in Quantum Field Theory II: Numerics, Interacting Theories and Higher Dimensions
Luca Capizzi, Cecilia De Fazio, Michele Mazzoni +2
In a recent paper we studied the entanglement content of zero-density excited states in complex free quantum field theories, focusing on the symmetry resolved entanglement entropy…
Rényi entropy and negativity for massless Dirac fermions at conformal interfaces and junctions
Luca Capizzi, Sara Murciano, Pasquale Calabrese
We investigate the ground state of a (1+1)-dimensional conformal field theory built with species of massless free Dirac fermions coupled at one boundary point via a conformal j…
Symmetry Resolved Entanglement of Excited States in Quantum Field Theory I: Free Theories, Twist Fields and Qubits
Luca Capizzi, Olalla A. Castro-Alvaredo, Cecilia De Fazio +2
The excess entanglement resulting from exciting a finite number of quasiparticles above the ground state of a free integrable quantum field theory has been investigated quite exten…
