Quantum Energy Inequalities from Local Thermal Equilibrium — •Jan Schlemmer and Rainer Verch — Inst. f. Theoretische Physik, Universität Leipzig, 04009 Leipzig

This talk will be about the relation between a certain notion of local thermality for states of the free scalar field on curved spacetime backgrounds and quantum energy inequalites. For states fulfilling the condition of local thermality we will present two results obtained together with for arbitrary curvature coupling: First a Quantum Weak Energy Inequality and second an expression for potential violations of the Averaged Null Energy Inequality, which involves only terms with a direct physical interpretation for the states under consideration. Furthermore this expression shows that examples proposed to point out limits to Quantum Energy Inequalities for nonminimally coupled scalar fields are already the worst case for the set of locally thermal states.
