Zero-mode entanglement across a conformal defect
Luca Capizzi, Viktor Eisler
We consider a free-fermion chain with a conformal defect that features an extended zero mode, and study the entanglement properties in its mixed ground state. The zero-mode induced…
Boundary Symmetry Breaking in CFT and the String Order Parameter
Riccarda Bonsignori, Luca Capizzi, Pantelis Panopoulos
We consider the ground state of a one-dimensional critical quantum system carrying a global symmetry in the bulk, which is explicitly broken by its boundary conditions. We probe th…
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…
Spreading of a local excitation in a Quantum Hierarchical Model
Luca Capizzi, Guido Giachetti, Alessandro Santini +1
We study the dynamics of the quantum Dyson hierarchical model in its paramagnetic phase. An initial state made by a local excitation of the paramagnetic ground state is considered.…
