Abstract: This talk will discuss what's new
with some of the most interesting looking cosmological tensions:
the Hubble tension, the growth of structure tension (S8, growth
rate, Lyman Alpha) and Big Bang Nucleosynthesis (Lithium and
Deuterium)...
Abstract: Quantizing classical systems we
consider Hilbert spaces equipped with representations of
canonical commutation relations (CCR). In the case of an
infinite number of degrees of freedom it is necessary to consider
representations of CCR...
Abstract: In this talk I review the
identification between quantum states in 3D AdS gravity and
Virasoro blocks in 2D CFT and describe the inner product on the
space of conformal blocks. I comment on the possible application of
these results to de...
Abstract: I will present some questions
and answers regarding the duality between 1+1-dimensional
superconformal field theory and type II string theory on $AdS_3
\times S^3 x T^4$.
For one unit of NS-NS 5-brane flux ($Q_5$=1), this string theory
has...
Abstract: We analyze a model of qubits which we
argue has an emergent quantum gravitational description similar to
the fermionic Sachdev-Ye-Kitaev (SYK) model. The model we consider
is known as the quantum $q$-spin model because it features
$q$...
Abstract: Conditional expectations on von
Neumann algebras have played a significant role in the development
of quantum information theory, and especially the study of quantum
error correction. In quantum gravity, it has been suggested
that...
Abstract: In this talk, I plan to review some
recent works on the study of three-dimensional quantum gravity. In
the first part, I will focus on pure $AdS_3$ gravity and review the
recent results on evaluating the gravity partition function
over...
