Bounds on relative modular Hamiltonians in general QFT
Adriano Chialastri, Christoph Minz, Ko Sanders
The relative entropy between two states is a key concept in quantum information theory and quantum field theory. In the setting of quantum field theory, its computation requires th…

Modular Hamiltonian of the massive scalar field on the half line: A numerical approach
Christoph Minz, Erik Tonni
We study the modular Hamiltonian of an interval for the ground state of a massive free scalar field on the half line with Robin boundary conditions, by employing a numerical method…

Modular Hamiltonian for fermions of small mass
Daniela Cadamuro, Markus B. Fröb, Christoph Minz
We consider the algebra of massive fermions restricted to a diamond in two-dimensional Minkowski spacetime, and in the Minkowski vacuum state. While the massless modular Hamiltonia…
