For a quantum field of arbitrary mass and spin in the static
patch of de Sitter spacetime, the Euclidean partition function
receives contributions from edge modes localized on the horizon,
expressible in terms of the Harish-Chandra character of the...
I will discuss the quantum resource known as magic and its
analysis in many-fermion systems such as the Sachdev-Ye-Kitaev
model. I will show that the SYK calculation of magic can be
quantitatively modeled with a gravity calculation
involving...
Inflation may have occurred at energies up to 10^16 GeV, far
beyond any terrestrial collider. The "cosmological collider"
program aims to extract the mass spectrum and spin content of
particles present during inflation from non-Gaussian
correlators...
We propose a Hamiltonian framework for constructing chiral
gauge theories on the lattice based on symmetry disentanglers:
constant-depth circuits of local unitaries that transform
not-on-site symmetries into on-site ones. When chiral symmetry can
be...
I will employ twistor string theory to construct a bulk dual of
N = 4 super Yang-Mills in the regime of weak 't Hooft coupling. I
will also discuss applications of this duality to the study of
scattering amplitudes, giant graviton correlators, and...
For Pauli stabilizer codes—such as surface codes and color
codes—transversal logical gates are strongly constrained by the
Bravyi–König bound. In particular, implementing a non-Clifford gate
transversally (as required for universality) demands three...
It is believed that topologically ordered gapped local
Hamiltonians in 2+1d consisting of commuting terms may not realize
a chiral anyon theory. There is even a formula that expresses the
chiral central charge of the edge theory as an integral of...
Conformal field theories in 3D are central to condensed-matter
and high-energy physics. Among them, critical gauge theories,
especially Chern-Simons-matter theories, stand out: They describe
transitions where one or both phases are topologically...
Entanglement Bootstrap is a research program to understand and
extract the universal data of quantum many body states from local
entanglement information. Since this universal data is
usually encoded in a quantum field theory, the program can
teach...
In this talk, I will discuss Cosmohedra. These are geometric
objects which encode the vacuum wavefunction for theories with
colored scalars with cubic interactions. I will start by
introducing the vacuum wavefunction, both in Minkowski and de
Sitter...
