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…
Quasi-equivalence of Gaussian states and energy estimates for functions of modular Hamiltonians
Adriano Chialastri, Ko Sanders
To compare two Gaussian states of the Weyl-CCR algebra of a free scalar QFT we study three closely related perspectives: (i) quasi-equivalence of the GNS-representations, (ii) diff…
Stress tensor bounds on quantum fields
Ko Sanders
The singular behaviour of quantum fields in Minkowski space can often be bounded by polynomials of the Hamiltonian . These so-called -bounds and related techniques allow us t…
On separable states in relativistic quantum field theory
Ko Sanders
We initiate an investigation into separable, but physically reasonable, states in relativistic quantum field theory. In particular we will consider the minimum amount of energy den…
Static symmetric solutions of the semi-classical Einstein-Klein-Gordon system
Ko Sanders
We consider solutions of the semi-classical Einstein-Klein-Gordon system with a cosmological constant , where the spacetime is given by Einstein's static metric on…
Energy conditions in general relativity and quantum field theory
Eleni-Alexandra Kontou, Ko Sanders
This review summarizes the current status of the energy conditions in general relativity and quantum field theory. We provide a historical review and a summary of technical results…
