Quantitative reasoning tasks which can involve mathematics,
science, and programming are often challenging for machine learning
models in general and for language models in particular. We show
that transformer-based language models obtain...
Symmetries of Quantum Field Theories (QFTs), whose fusion does
not satisfy a group multiplication law, are generally referred to
as non-invertible. I will discuss their connection to generalized
gauging and higher fusion categories, providing by...
Motivated by holographic duality and the Ryu-Takyanagi formula,
we ask the question, “What quantum problem are Einstein’s equations
solving?” Answering this question amounts to dissecting or
“deconstructing” AdS/CFT to identify the quantum...
In this talk I will discuss about Amplituhedra – generalizations
of polytopes inside the Grassmannian – introduced by physicists as
one of the new geometric constructions encoding physical
observables in Quantum Field Theories. In particular, I will...
This talk reviews the use of radial quantization to compute
Chern-Simons partition functions on handlebodies of arbitrary
genus. The partition function is given by a particular transition
amplitude between two states which are defined on the
Riemann...
Monte Carlo simulation is a powerful tool to study the Euclidean
path integral. In the context of gauge/gravity duality, it enables
us to access the strong-coupling regime of the QFT side. In this
talk, we provide the latest results of the...
Radiation emitted from evaporating black holes is highly mixed,
at least for times prior to the so-called "Page time." Usually, the
quantum state of the radiation is then treated as void of
information. I will discuss two ways in which this early...
In contrast to symmetry breaking phases of matter,
unconventional phases like spin liquids feature long-range quantum
entanglement and relate to the deconfined phases of gauge theories.
However, the realization of these states in materials
has...
As has been known since the 90s, there is an integrable
structure underlying two-dimensional gravity theories. Recently,
two-dimensional gravity theories have regained an enormous amount
of attention, but now in relation with quantum chaos -...
I will discuss the potential importance of a dark-sector phase
transition in the early universe in setting the measured relic
abundance, for a simple scenario with strongly interacting dark
matter. Enhancement of the dark matter density within...
