Continuity of KMS States for Quantum Fields on Manifolds
J. Damek
We show that pure, quasifree states, as well as regular (i.e., those with a unique vacuum) quasifree ground and KMS states, for linear quantum fields in a curved spacetime, are alw…

The scaling limits of KMS states on the Rindler horizon
J. Damek
The standard concept of scaling limits of distributions on manifolds is reformulated, and then a new framework for scaling at boundary points is provided. Next, we introduce a clas…

Stability of the Bose-Einstein condensate under polynomial perturbations
R. Gielerak, J. Damek
The problem of the Bose-Einstein condensate preservation under thermofield and standard gauge-invariant perturbations is discussed. A new result on stability of the condensate unde…
