Understanding the nature of dark matter is one of the major
goals of modern physics. The abundance and density profiles
of dark matter halos depend directly on dark matter particle
physics. Strong gravitational lensing enables a direct
measurement...
Abstract: An intrinsic quantity characterizing
a scale-invariant quantum field theory (SFT) is its thermal mass
gap, controlling its correlation length at finite temperature. By
scale-invariance, this is a pure number in units of the
temperature...
Abstract: In this talk we will
describe categorical symmetries of spin chains from the
viewpoint of subalgebras of the quasi-local algebra of observables
in the infinite volume limit. In particular, we provide
formal axioms for a subalgebra to give...
Abstract: We consider dispersive bounds on
Wilson coefficients of scalar effective field theories (EFT)
coupled to gravity in various spacetime dimensions, including the
contributions from graviton loops to the sum rules at low energies.
Dispersion...
Abstract: Astrophysical events such as
core-collapse supernovae (SN) and neutron star mergers offer unique
opportunities to explore physics beyond the Standard Model. In this
seminar, I will provide an overview of the mechanisms underlying
these...
Abstract: It is well-known that amplitudes in
Yang-Mills theory are severely constrained by the requirement of
gauge invariance. In this talk, I will explore two aspects of YM
amplitudes where (surface) gauge invariance plays a paramount role.
First...
