Speaker: Alexander Monin
Subject: The spontaneous breaking of a metastable string
We consider the phase transition of a string with tension to a string with a smaller tension . The transition proceeds through quantum tunneling, and we calculate in arbitrary number of dimensions the pre-exponential factor multiplying the leading semiclassical exponential expression for the rate of the process. At the found formula for the decay rate also describes a break up of a metastable string into two pieces.
