Coupling and thermal equilibrium in general-covariant systems
Goffredo Chirco, Hal M. Haggard, Carlo Rovelli
A fully general-covariant formulation of statistical mechanics is still lacking. We take a step toward this theory by studying the meaning of statistical equilibrium for coupled, p…
The boundary is mixed
Eugenio Bianchi, Hal M. Haggard, Carlo Rovelli
We show that Oeckl's boundary formalism incorporates quantum statistical mechanics naturally, and we formulate general-covariant quantum statistical mechanics in this language. We…
Lightcurves of Stars & Exoplanets: Estimating Inclination, Obliquity, and Albedo
Nicolas B. Cowan, Pablo A. Fuentes, Hal M. Haggard
[Abridged] Distant stars and planets will remain spatially unresolved for the foreseeable future. It is nonetheless possible to infer aspects of their brightness markings and viewi…
Death and resurrection of the zeroth principle of thermodynamics
Hal M. Haggard, Carlo Rovelli
The zeroth principle of thermodynamics in the form "temperature is uniform at equilibrium" is notoriously violated in relativistic gravity. Temperature uniformity is often derived…
