Abstract: The Standard Model of particle
physics grapples with notable gaps, failing to elucidate critical
aspects of our universe, such as the existence of dark matter and
the intriguing baryon-antibaryon asymmetry. Unraveling the
mysteries...
Abstract: I will discuss a gauge invariant
"memory" observable on cosmological horizons that controls the
existence of (normalizable) de Sitter invariant vacuum states.
While most of the discussion will concern free quantum field
theories, I will...
Abstract: A remarkably simple idea makes
it possible to put global positive coordinates on moduli spaces of
curves. I will give an update on recent developments in
understanding these coordinates and applying them moduli space
integrals. Interesting...
Abstract: Continuous Spin Particles (CSPs)
arise naturally from Wigner's classification of the unitary
representations of the Poincare group. Conversely, defining an
interacting (quantum field) theory for these particles is
notoriously difficult. In...
Abstract: Classical black holes obey laws of
thermodynamics, which suggests that quantum black holes are
complicated statistical systems. This supposition has been
validated in specific examples using string theory and holography,
but a general...
Abstract: Arising in hidden sector models of
dark matter, millicharged particles could be produced copiously at
facilities such as the LHC. However, due to their very small energy
depositions, large detectors like CMS or ATLAS are blind to
such...
