"Vacuum-like" Hadamard states for quantum fields on curved spacetimes
Marcos Brum, Klaus Fredenhagen
We present a modification of the recently proposed Sorkin-Johnston states for scalar free quantum fields on a class of globally hyperbolic spacetimes possessing compact Cauchy hype…

States of Low Energy in Homogeneous and Inhomogeneous, Expanding Spacetimes
Kolja Them, Marcos Brum
We construct states on the algebra of the Klein-Gordon field that minimize the energy density in homogeneous and in inhomogeneous spacetimes, both with compact Cauchy hypersurfaces…
