Numerical approach to the modular operator for fermionic systems
Henning Bostelmann, Daniela Cadamuro, Christoph Minz
We numerically approximate the Tomita-Takesaki modular operator for local subalgebras of the 1+1-dimensional massive Majorana field. Our method works at the one-particle level with…
Quantum inequalities in thermal states
Henning Bostelmann, Daniela Cadamuro, Leonardo Sangaletti
In thermal quantum field theory, the global Liouvillian (the generator of time translations) is passive. How is this reflected in the properties of its local density, a quantum fie…
Quantum energy inequalities in integrable models with several particle species and bound states
Henning Bostelmann, Daniela Cadamuro, Jan Mandrysch
We investigate lower bounds to the time-smeared energy density, so-called quantum energy inequalities (QEI), in the class of integrable models of quantum field theory. Our main res…
On the mass dependence of the modular operator for a double cone
Henning Bostelmann, Daniela Cadamuro, Christoph Minz
We present a numerical approximation scheme for the Tomita-Takesaki modular operator of local subalgebras in linear quantum fields, working at one-particle level. This is applied t…
Fermionic integrable models and graded Borchers triples
Henning Bostelmann, Daniela Cadamuro
We provide an operator-algebraic construction of integrable models of quantum field theory on 1+1 dimensional Minkowski space with fermionic scattering states. These are obtained b…
Relative entropy of coherent states on general CCR algebras
Henning Bostelmann, Daniela Cadamuro, Simone Del Vecchio
For a subalgebra of a generic CCR algebra, we consider the relative entropy between a general (not necessarily pure) quasifree state and a coherent excitation thereof. We give a un…
