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...
Abstract: Is there a geometric object
underlying the cosmological wavefunction for Tr $\phi^3$ theory,
just as associahedra underlie scattering amplitudes? In this talk,
I will describe a new class of polytopes that answer this question.
I will...
Abstract: I will discuss progress in the
programme of establishing a holographic duality for regular tilings
of hyperbolic space. As candidate boundary theories, we consider
spin chains with aperiodic couplings whose ground state may be
represented...
Abstract: In this talk, I will present
recent advances in the understanding of mesonic bound states in 2d
QCD, obtained by employing synergy integrability techniques and the
S-Matrix bootstrap. This talk will be based on 2406.11078, 2312.15598 (with...
Abstract: Event Horizon Telescope studies
prefer Magnetically Arrested Disk (MAD) accretion flows over their
more weakly magnetized Standard and Normal Evolution (SANE)
counterparts. These models produce efficient jets via the
Blandford-Znajek (BZ)...
Abstract: I will discuss dilaton gravity with a
sine potential, where periodic shifts of the dilaton (that leave
the potential invariant) are treated as a redundancy. Most things I
will say hold true for generic periodic potentials, but the
sine...
Abstract: Radio pulses from rotating neutron
stars provide us with spectacularly accurate measurements of their
spin frequencies. Surprisingly, young and middle-aged pulsars
frequently exhibit irregular evolution of their spin frequencies,
with long...
Abstract: I will discuss a geometric approach
to the factorization puzzle that involves coadjoint orbits and
Berry phases. The mathematical formalism introduced is applied both
to quantum mechanics examples and to AdS/CFT. It is shown how
the...
