Quantum Area Fluctuations from Gravitational Phase Space
Luca Ciambelli, Temple He, Kathryn M. Zurek
We study the gravitational phase space associated to a stretched horizon within a finite-sized causal diamond in -dimensional spacetimes. By imposing the Raychaudhuri equati…
Quantum Mechanics of a Spherically Symmetric Causal Diamond in Minkowski Spacetime
Mathew W. Bub, Temple He, Prahar Mitra +2
We construct the phase space of a spherically symmetric causal diamond in -dimensional Minkowski spacetime. Utilizing the covariant phase space formalism, we identify the re…
Diamond of Infrared Equivalences in Abelian Gauge Theories
Temple He, Prahar Mitra, Kathryn M. Zurek
We demonstrate a tree-level equivalence between four distinct infrared objects in -dimensional abelian gauge theories. These are () the large gauge charge …
Rindler Fluids from Gravitational Shockwaves
Sang-Eon Bak, Cynthia Keeler, Yiwen Zhang +1
We study a correspondence between gravitational shockwave geometry and its fluid description near a Rindler horizon in Minkowski spacetime. Utilizing the Petrov classification that…
An On-Shell Derivation of the Soft Effective Action in Abelian Gauge Theories
Temple He, Prahar Mitra, Allic Sivaramakrishnan +1
We derive the soft effective action in -dimensional abelian gauge theories from the on-shell action obeying Neumann boundary conditions at timelike and null infinity and Dir…
From Shockwaves to the Gravitational Memory Effect
Temple He, Ana-Maria Raclariu, Kathryn M. Zurek
We study the relationship between shockwave geometries and the gravitational memory effect in four-dimensional asymptotically flat spacetime. In particular, we show the 't Hooft co…
Stochastic Description of Near-Horizon Fluctuations in Rindler-AdS
Yiwen Zhang, Kathryn M. Zurek
We study quantum spacetime fluctuations near light-sheet horizons associated with a Rindler wedge in AdS spacetime, in the context of AdS/CFT. In particular, we solve the vacuum Ei…
Modular Fluctuations from Shockwave Geometries
Erik Verlinde, Kathryn M. Zurek
Modular fluctuations have previously been shown to obey an area law . Furthermore, modular fluctuations generate fluctuation…
Near-Horizon Quantum Dynamics of 4-d Einstein Gravity from 2-d JT Gravity
Sergei Gukov, Vincent S. H. Lee, Kathryn M. Zurek
We study quantum fluctuations in the lightcone metric of the 4-d Einstein-Hilbert action via dimensional reduction to Jackiw-Teitelboim (JT) gravity. In particular, we show that, i…
Conformal Description of Near-Horizon Vacuum States
Thomas Banks, Kathryn M. Zurek
Motivated by recent work suggesting observably large spacetime fluctuations in the causal development of an empty region of flat space, we conjecture that these metric fluctuations…
On Vacuum Fluctuations in Quantum Gravity and Interferometer Arm Fluctuations
Kathryn M. Zurek
We propose a simple model of spacetime vacuum fluctuations motivated by AdS/CFT, where the vacuum is described by a thermal density matrix, $ρ= \frac{e^{-K}}{\mbox{Tr}(e^{-K})}$ wi…
Spacetime Fluctuations in AdS/CFT
Erik Verlinde, Kathryn M. Zurek
We compute fluctuations in the modular energy of the vacuum associated with a Rindler-wedge in AdS spacetime in the context of AdS/CFT. We discuss the possible effect of these ener…
Is a Higgs Vacuum Instability Fatal for High-Scale Inflation?
John Kearney, Hojin Yoo, Kathryn M. Zurek
We study the inflationary evolution of a scalar field with an unstable potential for the case where the Hubble parameter during inflation is larger than the instability sca…
A Unified Approach to Cosmic Acceleration
Minjoon Park, Scott Watson, Kathryn M. Zurek
We present a unified framework for the study of late time cosmic acceleration. Using methods of effective field theory, we show that existing proposals for late time acceleration c…
