Abstract: Muon colliders offer a unique path to
multi-TeV, high-luminosity lepton collisions. Muon collisions with
a center-of-mass energy of 10 TeV or above would offer significant
discovery potential where the constituent collision energies
exceed...
Abstract: Some of the most fascinating
phenomena in nature arise when electrons behave as quantum
mechanical waves that interact with one another. But how can we
visualize these electronic waves in action? In this talk, I will
introduce the Quantum...
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.
Second, I will present computations of interaction rates for...
Abstract: Matroids are combinatorial
abstractions of the notion of linear independence. They are one of
the main objects studied in the current special year in the School
of Mathematics. I will talk about a notion of scattering amplitudes
for...
Abstract: Pulsar timing array experiments
around the world have recently published the first evidence of
nanohertz gravitational waves in the form of a stochastic
gravitational wave background. This discovery opens another window
on the...
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...
