The talk will consist of some general observations about energy
inequalities, such as the statement that the energy density
averaged over a time-like curve is bounded below and the statement
that the averaged null energy on a null geodesic in...
We will comment on wormholes for the off-diagonal components of
the density matrix of Hawking radiation. Then we will discuss work
in progress on a simple model in which small effects associated
with unitarity of time evolution may be related to...
The quest to build and probe toy models of quantum gravity in
table-top experiments presents a new frontier for the field of
quantum simulation. One challenge is to simulate fast scrambling of
quantum information in black holes, for which a key...
We start by describing how generalized symmetries in QFT arise
in the violation of elementary properties that appear when we
associate algebras to regions in QFT. This observation provides a
new perspective/proof of the abelian nature of generalized...
I will discuss recent progress in understanding quantum gravity
amplitudes (partition function, boundary correlation functions and
multiboundary amplitudes) in Liouville gravity, and how they limit
to Jackiw-Teitelboim (JT) amplitudes. I will...
Could quantum circuit complexity have physical ramifications? In
the context of AdS/CFT, Susskind has suggested that it might, as
circuit complexity could be the CFT dual to AdS wormhole volume.
Here we explore this proposal using cryptographic...
I will discuss real-time path integrals in gravitational
theories. As applications we will describe the general structure of
replica wormhole saddles and the effective dynamics of open quantum
systems with long-term memory.
In recent work, it was argued that quantum computations with
inputs and outputs distributed in spacetime, or quantum tasks,
impose constraints on entanglement in holographic theories. The
resulting constraint was named the connected wedge theorem...
I will discuss progress towards understanding the relationship
between the gravitational path integral and the partition function
via the gravitational free energy (more generally the generating
functional). A proper computation of the free energy...
NASA's Kepler mission conducted a large survey of planetary
systems. Recently, we have advanced from measuring occurrence
rates as a function of planet size and period to characterizing the
intrinsic distribution of planetary system
architectures. ...
