Entanglement Hamiltonian for inhomogeneous free fermions
Riccarda Bonsignori, Viktor Eisler
We study the entanglement Hamiltonian for the ground state of one-dimensional free fermions in the presence of an inhomogeneous chemical potential. In particular, we consider a lat…

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…
