High Energy Theory Seminar
Online and In-Person Event
Exploring Entropy-Positivity Bounds
Rachel Rosen,
Carnegie Mellon University,
Positivity bounds provide powerful constraints on the Wilson coefficients of low energy effective theories. However, generalizing such constraints to systems in which Lorentz invariance is broken — such as in cosmology or condensed matter systems — remains notoriously difficult. Recently, it has been suggested that the physical requirement that a system's entropy should increase when accounting for microscopic degrees of freedom might be used to constrain low energy theories even in the absence of Lorentz invariance. In this talk I discuss a variety of examples that support such a conjecture as well as interesting counterexamples that seem to limit its scope.
The talk is in 469 Lauritsen.
