Abstract: Fusion surface models, as
introduced by Inamura and Ohmori, extend the concept of anyon
chains to 2+1 dimensions, taking fusion 2-categories as their
input. In this talk, I will focus on fusion surface models
constructed from braided...
Abstract: I will present several results on
linear and nonlinear models, relating to the problem of
stability/instability of the exterior region (up to and including
the event horizon) of extremal Reissner-Nordstrom black hole
spacetimes.
Abstract: A sharp definition of what
“adiabatic” means is given; it is then shown that the
time-dependent expectation value of a quantum-mechanical observable
in the adiabatic limit can be expressed— in many cases—by means of
the appropriate Berry...
Abstract: String theory offers a unique
perspective on concrete questions about the nature of quantum
gravity. I will review how such questions can be formulated in
terms of the string theory S-matrix at high energies. Attempts to
sharpen the S...
Abstract: The detection of Gravitational Waves
(GWs) from binary black hole coalescences offers a powerful tool
for exploring the strong-field regime of General Relativity (GR).
To ensure the reliability of these tests, it is essential to
identify...
