Pure and physics-guided deep learning approaches for spatio-temporal groundwater level prediction
Matteo Salis, Gabriele Sartor, Rosa Meo +2
Groundwater represents a key element of the water cycle, yet it exhibits complex and context-dependent relationships that make its modeling challenging. Theory-based models have be…
ADE Minimal Strings and Multi-Matrix Duals
Victor A. Rodriguez, Mykhaylo Usatyuk, Zi-Yue Wang
We revisit ADE minimal string theories, focusing on the D- and E-series minimal models coupled to Liouville theory. Unlike the A-series, whose duals are solvable two-matrix models,…
The evaporation of black holes in supergravity
Guanda Lin, Luca V. Iliesiu, Mykhaylo Usatyuk
In supergravity, charged rotating black holes are generically driven towards becoming extremal and supersymmetric through the emission of Hawking radiation. Eventually, as the blac…
Quantum mechanics and observers for gravity in a closed universe
Daniel Harlow, Mykhaylo Usatyuk, Ying Zhao
Recent arguments based on the quantum extremal surface formula or the gravitational path integral have given fairly compelling evidence that the Hilbert space of quantum gravity in…
The evaporation of charged black holes
Adam R. Brown, Luca V. Iliesiu, Geoff Penington +1
Charged particle emission from black holes with sufficiently large charge is exponentially suppressed. As a result, such black holes are driven towards extremality by the emission…
God of the Gaps: Random matrix models and the black hole spectral gap
Clifford V. Johnson, Mykhaylo Usatyuk
We show that random matrix models are a natural tool for understanding the appearance of a large gap in the microstate spectrum of black holes when there is a high degeneracy of st…
Closed universes, factorization, and ensemble averaging
Mykhaylo Usatyuk, Ying Zhao
We study closed universes in holographic theories of quantum gravity. We argue that within any fixed theory, factorization implies there is one unique closed universe state. The wa…
Closed universes in two dimensional gravity
Mykhaylo Usatyuk, Zi-Yue Wang, Ying Zhao
We study closed universes in simple models of two dimensional gravity, such as Jackiw-Teiteilboim (JT) gravity coupled to matter, and a toy topological model that captures the key…
Revisiting the second order formalism of JT gravity
Guanda Lin, Mykhaylo Usatyuk
We revisit the gravity path integral formalism of JT gravity. We explain how to gauge fix the path integral in the presence of asymptotic boundaries and conical defects, and resolv…
The Lion, the Witch, and the Wormhole: Ensemble averaging the symmetric product orbifold
Joshua Kames-King, Alexandros Kanargias, Bob Knighton +1
We consider the ensemble average of two dimensional symmetric product orbifold CFTs over the Narain moduli space. We argue for a bulk dual given by …
Comments on Lorentzian topology change in JT gravity
Mykhaylo Usatyuk
We propose a definition for the Lorentzian Jackiw-Teitelboim (JT) gravity path integral that includes Lorentzian topology changing configurations. The construction is inspired by t…
Microstructure in matrix elements
Andreas Blommaert, Mykhaylo Usatyuk
We investigate the simple model of Pennington, Shenker, Stanford and Yang for modeling the density matrix of Hawking radiation, but further include dynamics for EOW branes behind t…
Dilaton-gravity, deformations of the minimal string, and matrix models
Gustavo J. Turiaci, Mykhaylo Usatyuk, Wayne W. Weng
A large class of two-dimensional dilaton-gravity theories in asymptotically AdS spacetimes are holographically dual to a matrix integral, interpreted as an ensemble average ove…
Quantum Maximin Surfaces
Chris Akers, Netta Engelhardt, Geoff Penington +1
We formulate a quantum generalization of maximin surfaces and show that a quantum maximin surface is identical to the minimal quantum extremal surface, introduced in the EW prescri…
Bulk Reconstruction Beyond the Entanglement Wedge
Ning Bao, Aidan Chatwin-Davies, Benjamin E. Niehoff +1
We study the portion of an asymptotically Anti de Sitter geometry's bulk where the metric can be reconstructed, given the areas of minimal 2-surfaces anchored to a fixed boundary s…
Wormhole Traversability via Quantum Random Walks
Ning Bao, Vincent P. Su, Mykhaylo Usatyuk
In this work we seek to generalize the connection between traversable wormholes and quantum channels. We do this via a connection between traversable wormholes and graph geometries…
Dynamics and interactions of particles in a thermophoretic trap
Benjamin Foster, Frankie Fung, Connor Fieweger +4
We investigate dynamics and interactions of particles levitated and trapped by the thermophoretic force in a vacuum cell. Our analysis is based on footage taken by orthogonal camer…
Stable thermophoretic trapping of generic particles at low pressures
Frankie Fung, Mykhaylo Usatyuk, B. J. DeSalvo +1
We demonstrate levitation and three-dimensionally stable trapping of a wide variety of particles in a vacuum chamber through the use of the thermophoretic force in the presence of…
