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…
Quantization, dequantization, and distinguished states
Eli Hawkins, Christoph Minz, Kasia Rejzner
Geometric quantization is a natural way to construct quantum models starting from classical data. In this work, we start from a symplectic vector space with an inner product and --…
Asymptotic measurement schemes for every observable of a quantum field theory
Christopher J. Fewster, Ian Jubb, Maximilian H. Ruep
In quantum measurement theory, a measurement scheme describes how an observable of a given system can be measured indirectly using a probe. The measurement scheme involves the spec…
An algebraic QFT approach to the Wetterich equation on Lorentzian manifolds
Edoardo D'Angelo, Nicolò Drago, Nicola Pinamonti +1
We discuss the scaling of the effective action for the interacting scalar quantum field theory on generic spacetimes with Lorentzian signature and in a generic state (including vac…
