Abstract: Recent developments in massive
on-shell scattering amplitudes in 4D have opened the door to
understanding particle physics efficiently from an on-shell
point-of-view, including on-shell notions of minimal coupling and
black holes as...
Abstract: A review of the concept of
Krylov Complexity(K- Complexity) will be presented. One feature of
K-Complexity is that its definition does not involve a tolerance
parameter.
I will describe some general properties of K-Complexity, its
behavior...
Abstract: This is an exciting time for stellar
astrophysics as high-cadence time domain surveys (Gaia, PTF, ZTF,
ATLAS, Kepler, TESS, and, in the near future, the Vera Rubin
Observatory) are revolutionizing the landscape of stellar studies
by...
Abstract: I will talk about the invariants of
topologically ordered states of quantum lattice systems that
generalize Berry classes and can be defined for any gapped state in
any dimension. The equivariant version of such invariants unifies
and...
Abstract: Gravitational waves have uncovered a
treasure trove of nearly 90 merging black holes and neutron stars,
each with its own unique story to tell. In the first part of the
talk, our focus will center on black hole spins, seeking to
decipher...
Abstract: While von Neumann entropies for
local subregions in quantum field theory universally contain
ultraviolet divergences, there is widespread belief that
differences between von Neumann entropies can be finite and
well-defined in many...
Pulsar timing arrays {PTAs) and gravitational wave detectors can
serve as valuable tools in the detection of dark matter. Dark
matter substructure within the Milky Way Galaxy can induce
gravitational pulls on pulsars, leading to observable...
Abstract: Recently, it has been argued
that in certain settings, the entropy of a region in semiclassical
quantum gravity can be computed in a UV-finite way using tools from
the theory of operator algebras. I will attempt to formulate the
most...
Abstract: Kinematically, massless particles in
Lorentz-invariant theories are classified by a dimensionful "spin
scale"ρ (2nd Casimir invariant) that characterizes
helicity states' mixing under little group transformations.
However, dynamics for...
