Following the fundamental insights from quantum mechanics and general relativity, geometry itself should have a quantum description; the search for a complete u

The subject of the exact renormalization group started from pioneering work by Wegner and Houghton in the early seventies and, a decade later, by Polchinski, wh

Absolute concepts of time and energy are integral to standard thermal physics, but background independent systems are devoid of them. This thesis explores the f
