Stability and Related Properties of Vacua and Ground States
Walter Wreszinski, Christian Jaekel
We consider the formal non relativistc limit (nrl) of the :ϕ^4:_{s+1} relativistic quantum field theory (rqft), where s is the space dimension. Following work of R. Jackiw, we show…
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…
Nuclearity and split for thermal quantum field theories
Christian Jaekel
We review the heuristic arguments suggesting that any thermal quantum field theory, which can be interpreted as a quantum statistical mechanics of (interacting) relativistic partic…
Cluster Estimates for Modular Structures
Christian Jaekel
The basic ingredients of Tomita-Takesaki modular theory are used to establish cluster estimates. Applications to thermal quantum field theory are discussed.
Decay of Spatial Correlations in Thermal States
Christian Jaekel
We study the cluster properties of thermal equilibrium states in theories with a maximal propagation velocity (such as relativistic QFT). Our analysis, carried out in the setting o…
