Many-body physics and resolvent algebras
Detlev Buchholz, Jakob Yngvason
Some advantages of the algebraic approach to many body physics, based on resolvent algebras, are illustrated by the simple example of non-interacting bosons which are confined in c…

Geometric Modular Action, Wedge Duality and Lorentz Covariance are Equivalent for Generalized Free Fields
Johanna Gaier, Jakob Yngvason
The Tomita-Takesaki modular groups and conjugations for the observable algebras of space-like wedges and the vacuum state are computed for translationally covariant, but possibly n…

There are No Causality Problems for Fermi's Two Atom System
Detlev Buchholz, Jakob Yngvason
A repeatedly discussed gedanken experiment, proposed by Fermi to check Einstein causality, is reconsidered. It is shown that, contrary to a recent statement made by Hegerfeldt, the…
