Local thermal equilibrium in relativistic quantum field theory |
Speaker: | Jan Schlemmer (University of Vienna) |
Abstract: | In the description of spatially extended physical systems one often assigns to them thermal quantities (temperature, pressure, ...) varying in space and time. While there is a well established theory (statistical mechanics) for linking the thermodynamic description of systems with constant temperature ("global equilibrium") to microscopic models, for the case of varying thermal parameters the situation is much less clear cut and in fact there are many proposed frameworks to link the microscopic and macroscopic level. In my talk I will present a framework especially suited for relativistic quantum field theory, talk about its generalization to quantum fields on curved spacetime and try to summarize some results obtained for specific systems, both on flat and curved spacetime. |

Is quantum gravity observable? |
Speaker: | Martin Bojowald (Penn State University) |
Abstract: | Conceptually, a combination of quantum mechanics with general relativity is required to understand fundamental space-time structures. Estimates of the relevant scales based on dimensional arguments, however, are not encouraging as regards observations. Quantum gravity
can be observable only if there are magnification effects of its corrections to general relativity or quantum field theory at least in some regimes. This talk discusses examples seen in recent research on loop quantum gravity. The main effects occur in early-universe
cosmology, and some of them might be relevant for particle physics as well.
