We give a pedagogical introduction to algebraic quantum field theory (AQFT), with the aim of explaining its key structures and features. Topics covered include: algebraic formulations of …
We explain and explore the connections among the following propositions:(1) thermal equilibrium is characterized by the KMS condition,< A t− iβ B>=< BA t>;(2) finite-temperature …
Black holes have presented us with some of the most baffling paradoxes in physics. From their original conception as dark stars, they have come to be understood as physical …

Abstract We consider the Klein-Gordon equation (m≧ 0) on the double Schwarzschild wedge of the Kruskal spacetime, and construct the Hartle-Hawking state ω H as a thermal …
The discovery of the radiation properties of black holes prompted the search for a natural candidate quantum ground state for a massless scalar field theory on Schwarzschild …
We consider the covariant Klein-Gordon equation (□ g g+ m 2) φ= 0 of mass m≥ 0 on the exterior Schwarzschild spacetime of mass M. We introduce and study a set of outer and …
Given any half-sided modular inclusion of standard subspaces, we show that the entropy function associated with the decreasing one-parameter family of translated standard …
