Minimax surfaces and the covariant holographic entropy cone
Guglielmo Grimaldi - Brandeis University
I will discuss work-in-progress for defining a new proposal for the covariant holographic entanglement entropy. The proposal instructs us to find maximal spacelike codimension-2 surfaces on timelike hypersurfaces in the bulk, followed by a minimization among all possible hypersurfaces in the right…
Is singularity resolution trivial?
Ding Jia - Toward a theory of everything
Many non-trivial ideas have been proposed to resolve singularities in quantum gravity. In this talk I argue that singularity resolution can be trivial in gravitational path integrals, because geodesically incomplete singular spacetimes are usually not included in the sum. For theories where this…
On the continuum limit of spin foams: graviton dynamics and area metric induced corrections
Athanasios Kogios - Perimeter Institute for Theoretical Physics
The semi-classical limit of spin foams leads to the Area Regge action. It was long thought that this action leads to flatness and does, in particular, not allow for propagating gravitons. I will present the first systematic studies of the continuum limit of the Area Regge action, using different…
Can Radio sky reveal primordial electron-proton interactions?
Maura Ramirez-Quezada - University of Sydney
The cosmic radio background (CRB) contains diffuse, discrete and cosmological emission sources from the universe. In this talk, I will discuss wether an additional contribution coming from low frequency photons is produced by free-free emission during the recombination era of the univers. These…
Excited state spectrum of strongly interacting magic-angle twisted bilayer graphene at three- quarters filling
Terrence Tai - University of Pennsylvania
The interplay between strong electronic interaction and non-trivial topology in magic-angle twisted bilayer graphene (tBLG) yields many intriguing phenomena that range from superconductivity to a spontaneous quantum anomalous Hall state with Chern number ±1. WIth the equilibrium phase diagram under…
Measurement-Protected Order in Monitored Quantum Circuits with Continuous Symmetry
Jacob Hauser - University of California, Santa Barbara
Monitored quantum circuits, composed of local unitary operators and projective measurements, have recently emerged as a rich setting for studying non-equilibrium quantum dynamics. In such systems, sufficient densities of measurements can protect a highly-monitored steady state phase with area law…
Reflecting scalar fields in numerical relativity
Conner Dailey - Friedrich Schiller University Jena
Black hole echoes have been considered as new probes to standard gravitational waveforms. Here, I consider reflections of scalar waves around a black hole as a model of black hole echoes arising from scalar fields. This problem is difficult due to the need for a proper understanding of the…
