Quantum pseudorandom states are efficiently preparable states
that are indistinguishable from truly Haar random states to an
efficient observer. First defined by Ji, Liu and Song, such states
have found a wide variety of applications in areas such...
Finding a gravitational description of black hole microstates is
an important problem in quantum gravity. In this talk we describe
how to reproduce the integer number of black hole microstates using
the Gibbons-Hawking gravitational path integral...
In double-scaled SYK, the chord diagrams of Berkooz et al. give
rise to a bulk algebra and geometry. The algebra is a "quantum
deformation" of the JT gravitational algebra that includes a
deformation of SL(2,R). The growth of operator size (in...
Spacetime wormholes can lead to surprises in black hole physics.
We show that a very old black hole can tunnel to a white
hole/firewall by emitting a large baby universe. We study the
process for a perturbed thermofield double black hole in
Jackiw...
One puzzling aspect of holography is that it conjectures a
duality between a physical theory with a single rigid causal
structure (the non-gravitational "boundary theory") and one whose
causal structure is state-dependent (the gravitational "bulk...
Cauchy slice holography gives a duality between the wavefunction
on a Cauchy slice and the partition function of a T2 deformed
field theory. I will review this correspondence and discuss
its implications for the black hole information puzzle.
The...
On August 17, 2017, LIGO/Virgo detected the first
gravitational waves from merging neutron stars. This event, known
as GW170817 was accompanied by observations all over the
electromagnetic spectrum. The peculiar gamma-ray burst that
followed the...
