In the first half of the talk, I will review the notion of
non-invertible symmetries and how they help us to analyze certain
strongly coupled QFTs like 2d Adjoint QCD. Then, I discuss the
representation theory of non-invertible symmetries and use
it...
Astronomical observations indicate that coherent, dynamically
important magnetic fields are ubiquitous in the Universe. However,
neither the origin problem -- what are the physical mechanisms that
generate the initial ``seed'' magnetic fields —- nor...
A primary scientific outcome of the Apollo program was the giant
impact theory for lunar origin, in which a collision at the end of
Earth’s main accretionary phase creates a disk from which the Moon
forms. In the past decade, the nature of a Moon...
Conformal blocks are fundamental objects in the conformal
bootstrap program of 2D conformal field theory and are closely
related to four dimensional supersymmetric gauge theory.
In this talk, I will demonstrate a probabilistic construction of
a...
Gravity plays the central role in structure formation and
evolution in astronomical scales. Despite the apparently simple
inverse square law for the gravitational force in the
non-relativistic regime, the dynamics of self-gravitating
many-body...
Millimeter-wave surveys of the sky have the potential for
yielding a wealth of information about our universe from the first
instants of its existence to our own solar system. I will describe
how modern measurements of the cosmic microwave...
