In the book of Haag [Local Quantum Physics (Springer Verlag, Berlin, 1992)] about local
quantum field theory the main results are obtained by the older methods of C*-and W …

Above the chiral symmetry restoration crossover around T ch∼ 155 MeV a new regime
arises in QCD, a stringy fluid, which is characterized by an approximate chiral spin symmetry …

These notes essentially reproduce lectures given at the International School for Advanced
Studies (Trieste) and at the Scuola Normale Superiore (Pisa) on various occasions. The …

The progress in the last decade in perturbative quantum field theory at high temperatures
and densities, made possible by the use of effective field theories and hard thermal/dense …

A bstract Spectral functions encode a wealth of information about the dynamics of any given
system, and the determination of their non-perturbative characteristics is a long-standing …

Some years ago, Radzikowski has found a characterization of Hadamard states for scalar
quantum fields on a four-dimensional globally hyperbolic spacetime in terms of a specific …

We present a covariant quantization scheme for the so-called “partially massless” graviton
field in de Sitter spacetime. Our approach is founded on the principles of the de Sitter group …

We show in this article that the Reeh–Schlieder property holds for states of quantum fields
on real analytic curved space–times if they satisfy an analytic microlocal spectrum condition …

We study free, covariant, quantum (Bose) fields that are associated with irreducible
representations of the Poincaré group and localized in semi-infinite strings extending to …

Quantum field theory (QFT) is widely viewed as one of the most successful theories in
science—it has predicted phenomena before they were observed in nature 2, and its …
