SITP Colloquia
Past Events
In this talk I will do three things. First, I will outline the conditions under which the interaction rate of inelastic processes with a system consisting of N targets scales as N^2.
Non-perturbative effects in string theory, such as D-branes, play an essential role in our current understanding of both quantum gravity and string-based models of the universe.
We begin with a review of generalized global symmetries and recent applications in studying phases of gauge theories.
On lattice systems, a global unitary evolution that has a notion of lightcone is not necessarily generated by a local Hamiltonian.
Resonances are as fundamental for the quantum description of unstable systems as energy eigenstates are for stable systems.
Should we include a sum over wormhole topologies in the path integral of quantum gravity?
