[Theory-seminars] Remote theory seminar next week

[Carlota Andres Casas]

Dear all,

Here is a reminder of next week remote theory seminar.

Theory seminar
Monday, May 18, 1:00 PM
Thomas Cohen (U. of Maryland), "Surprises in large N Thermodynamics"

Abstract:
The thermodynamic behavior of QCD at large N (where N is the number of colors) is interesting for many reasons.  In the hadronic domain, the thermodynamics is tied directly to spectroscopy.  The subject is quite old; it has been studied for decades.  Despite this, there are a number of features that are not widely appreciated and are quite surprising.  In this talk a few of these are noted given the assumption that QCD has a generic first-order phase transition at large N as one sees for pure gauge theory.  The existence of a first-order transition implies metastable phases. One surprise is that under this assumption large N QCD has a supercooled metastable plasma phase with negative absolute pressure---that is a pressure below that of the vacuum.  Another surprise concerns the region beyond the endpoint of the superheated hadronic which, at large N--rather than curving as one expects in an unstable region--is flat.
