Dr. Anzhong Wang

Abstract:

I shall first give a brief and basic introduction to anisotropic scalings of space and time introduced by Lifshitz in 1940's in order to make the scalar field renormalizable in condensed matter physics, and then apply them  to  gravity, as done recently by Horava, the so-called Horava-Lifshitz theory of quantum gravity. I  will explain in some detail its major challenges found so far, and show some very promising approaches  to resolve these problems. Finally, I  shall point  out some future work along the lines.
