Modular Hamiltonians for the massless Dirac field in the presence of a defect
Abstract We study the massless Dirac field on the line in the presence of a point-like defect characterised by a unitary scattering matrix, that allows both reflection and transmission. Considering this system in its ground state, we derive the modular Hamiltonians of the subregion given by the unio...
