We review our work concerning the decay of the false vacuum by quantum tunnelling transitions. When the false vacuum manifold is non-trivial, it can lock in topological defects. We have considered the possibility that these are magnetic monopoles, cosmic strings, domain walls and most recently, Skyrmions. In all of these cases, the topological defect must realize the true vacuum inside its...

We show how to obtain all conformal blocks from embedding space with the help of the operator product expansion. The minimal conformal block originates from scalar exchange in a four-point correlation functions of four scalars. All remaining conformal blocks are simple derivatives of the minimal conformal block. With the help of the orthogonality properties of the conformal blocks, the...

Progress in physics, from Aristotelian physics, to Galilean and Newtonian physics, and then to both special and general relativity, can be viewed as a continual refinement of the notion of a reference frame. The next natural step in this progression is the idea of a quantum reference frame. In this talk, I will introduce the basic tools that have been developed to study quantum reference...

In this work I would like to give semi-classical derivation of Hawking temperature from cylindricaly symmetric charged rotating black strings. I will use Hamilton Jacobi method and WKB approximation to get analytic expression for Hawking temperature of fermions tunneling from charged black strings.

A conformal field theory is a quantum field theory whose symmetries are extended from the Lorentz group to the conformal group, thus putting more constraints on the theory than what we normally have in regular quantum field theory. In 2 dimensions, the conformal symmetries are infinite dimensional so it is easier to characterize the properties of 2d CFTs than it is in higher dimensions....
