A sharpened nuclearity condition for massless fields

Wojciech Dybalski

A recently proposed phase space condition which comprises information about the vacuum structure and timelike asymptotic behavior of physical states is verified in massless free fi…

A sharpened nuclearity condition and the uniqueness of the vacuum in QFT

Wojciech Dybalski

It is shown that only one vacuum state can be prepared with a finite amount of energy and it appears, in particular, as a limit of physical states under large timelike translations…

Semi-classical trace formula, isochronous case. Application to conservative systems

Roch Cassanas

Under conditions of clean flow we compute the leading term in the STF when the set of periods of the energy surface is discrete. Comparing to the case of non-degenerate periodic or…

Phase space properties and the short distance structure in quantum field theory

Henning Bostelmann

The paper investigates relations between the phase space structure of a quantum field theory ("nuclearity") and the concept of pointlike localized fields. Given a net of local obse…

Scaling Analysis and Renormalisation Group for General (Quantum) Many Body Systems in the Critical Regime

Manfred Requardt

With the help of a smooth scaling and coarse-graining approach of observables, developed recently by us in the context of so-called fluctuation operators (inspired by prior work of…

Asymptotic Abelianness and Braided Tensor C*-Categories

Detlev Buchholz, Sergio Doplicher, Giovanni Morchio +2

By introducing the concepts of asymptopia and bi-asymptopia, we show how braided tensor C*-categories arise in a natural way. This generalizes constructions in algebraic quantum fi…
