Gravity at a Lifshitz Point

Conference Date: 
Sunday, November 8, 2009 (All day) to Tuesday, November 10, 2009 (All day)


The construction of a quantum theory of gravity might require us to give up one or more of the fundamental principles of standard quantum field theory. A recent proposal dispensing with Lorentz invariance builds upon an analogy with condensed matter systems characterized by a Lifshitz point. This proposal also seems to produce a theory which is well behaved in the ultraviolet regime.


This workshop intends to bring together researchers working on this or related ideas. The focus will be on the viability of the proposal (compatibility with large scale phenomenology and renormalizabilty) and its relation to other research directions, like causal dynamical triangulations and aether theories.
