Can Relativity be an Emergent Principle?


In a system with strongly interacting degrees of freedom, symmetries can emerge in the low energy sector which are not present in the microscopic Hamiltonians. In this talk, I shall show many examples in condensed matter physics, where the relativistic invariance is a derived property of the low energy sector, rather than a postulated principle. I shall outline a program in which one attempts to construct models of fundamental interactions based on the idea of emergent relativity.
