Spectral and scattering theory for space-cutoff models with variable metric
Christian Gérard, Annalisa Panati
We consider space-cutoff models with a variable metric of the form \[ H= \d\G(ω)+ \int_{\rr}g(x):P(x, φ(x)):\d x, \] on the bosonic Fock space $L^{2}(\rr)$, where the ki…
Generalized definition of time delay in scattering theory
C. Gerard, R. Tiedra de Aldecoa
We advocate for the systematic use of a symmetrized definition of time delay in scattering theory. In two-body scattering processes, we show that the symmetrized time delay exists…
Thermal Quantum Fields without Cut-offs in 1+1 Space-time Dimensions
Christian Gerard, Christian Jaekel
We construct interacting quantum fields in 1+1 dimensional Minkowski space, representing neutral scalar bosons at positive temperature. Our work is based on prior work by Klein and…
Thermal Quantum Fields with Spatially Cut-off Interactions in 1+1 Space-time Dimensions
Christian Gerard, Christian Jaekel
We construct interacting quantum fields in 1+1 space-time dimensions, representing charged or neutral scalar bosons at positive temperature and zero chemical potential. Our work is…
