KMSlike Properties of Local Equilibrium States in Quantum Field Theory
, 2015
"... A new condition, called “Local KMS Condition”, characterizing states of a quantum field to which one can ascribe, at a given spacetime point, a temperature, is introduced in this article. It will be shown that the Local KMS Condition (LKMS condition) is equivalent to the Local Thermal Equilibrium (L ..."

(LTE) condition, proposed previously by Buchholz, Ojima and Roos, for states of the quantized scalar KleinGordon field that fulfill the analytic microlocal spectrum condition. Therefore, known examples of states fulfilling the LTE condition provide examples of states obeying the LKMS condition with a
Continuity of symplectically adjoint maps and the algebraic structure of Hadamard vacuum representations for quantum fields on curved spacetime

"... We derive for a pair of operators on a symplectic space which are adjoints of each other with respect to the symplectic form (that is, they are sympletically adjoint) that, if they are bounded for some scalar product on the symplectic space dominating the symplectic form, then they are bounded with ..."

We derive for a pair of operators on a symplectic space which are adjoints of each other with respect to the symplectic form (that is, they are sympletically adjoint) that, if they are bounded for some scalar product on the symplectic space dominating the symplectic form, then they are bounded with respect to a oneparametric family of scalar products canonically associated with the initially given one, among them being its “purification”. As a typical example we consider a scalar field on a globally hyperbolic spacetime governed by the KleinGordon equation; the classical system is described by a symplectic space and the temporal evolution by symplectomorphisms (which are symplectically adjoint to their inverses). A natural scalar product is that inducing the classical energy norm, and an application of the above result yields that its “purification ” induces on the oneparticle space of the quantized system a topology which coincides with that given by the twopoint functions of quasifree Hadamard states. These findings will be shown to lead to new results concerning the structure of the local (von Neumann) observablealgebras in representations of quasifree Hadamard states of the KleinGordon field in an arbitrary globally hyperbolic spacetime, such as local definiteness, local primarity and Haagduality (and also split and type III1properties). A brief review of this circle of notions, as well as of properties of Hadamard states, forms part of the article.

The principle of local covariance which was recently introduced admits a generally covariant formulation of quantum field theory. It allows a discussion of structural properties of quantum field theory as well as the perturbative construction of renormalized interacting models on generic curved backgrounds and opens in principle the way towards a background independent perturbative quantization of gravity. 1
