Spacetime topology and geometry in JT Gravity from non-crossing permutations
Curtis T. Asplund, Nicholas A. Parrilla
We study how discrete parameters which enumerate non-crossing permutations become geometric quantities in JT gravity. Analyzing non-crossing permutations on the disk together with…
Quantum chaos and pole skipping in two-dimensional conformal perturbation theory
Curtis T. Asplund, Sebastian Fischetti, Alexandra Miller +1
We analyze pole skipping of stress tensor two-point functions in two-dimensional quantum field theories perturbed away from conformality by a relevant deformation. The retarded two…
Predictive complexity of quantum subsystems
Curtis T. Asplund, Elisa Panciu
We define predictive states and predictive complexity for quantum systems composed of distinct subsystems. This complexity is a generalization of entanglement entropy. It is inspir…
Equivalence of Emergent de Sitter Spaces from Conformal Field Theory
Curtis T. Asplund, Nele Callebaut, Claire Zukowski
Recently, two groups have made distinct proposals for a de Sitter space that is emergent from conformal field theory (CFT). The first proposal is that, for two-dimensional holograp…
Massive quiver matrix models for massive charged particles in AdS
Curtis T. Asplund, Frederik Denef, Eric Dzienkowski
We present a new class of supersymmetric quiver matrix models and argue that it describes the stringy low-energy dynamics of internally wrapped D-branes in four-dimens…
Entanglement Scrambling in 2d Conformal Field Theory
Curtis T. Asplund, Alice Bernamonti, Federico Galli +1
We investigate how entanglement spreads in time-dependent states of a 1+1 dimensional conformal field theory (CFT). The results depend qualitatively on the value of the central cha…
Entanglement entropy converges to classical entropy around periodic orbits
Curtis T. Asplund, David Berenstein
We consider oscillators evolving subject to a periodic driving force that dynamically entangles them, and argue that this gives the linearized evolution around periodic orbits in a…
Holographic Entanglement Entropy from 2d CFT: Heavy States and Local Quenches
Curtis T. Asplund, Alice Bernamonti, Federico Galli +1
We consider the entanglement entropy in 2d conformal field theory in a class of excited states produced by the insertion of a heavy local operator. These include both high-energy e…
Mutual information after a local quench in conformal field theory
Curtis T. Asplund, Alice Bernamonti
We compute the entanglement entropy and mutual information for two disjoint intervals in two-dimensional conformal field theories as a function of time after a local quench, using…
Large N classical dynamics of holographic matrix models
Curtis T. Asplund, David Berenstein, Eric Dzienkowski
Using a numerical simulation of the classical dynamics of the plane-wave and flat space matrix models of M-theory, we study the thermalization, equilibrium thermodynamics and fluct…
Holographic entanglement entropy beyond coherent states
Curtis T. Asplund
We study entanglement entropy for a class of states in quantum field theory that are entangled superpositions of coherent states with well-separated supports, analogous to Einstein…
Classification of Einstein metrics on the product of an interval with a three-sphere
Curtis T. Asplund, Brian Krummel, Evan Merrell +2
We present a complete classification of Einstein metrics on the space M = I \times S^3, where I is the interval (0,l) or (0,\infty) or their closures, and we consider separate metr…
Evolution of entanglement entropy in the D1-D5 brane system
Curtis T. Asplund, Steven G. Avery
We calculate the evolution of the geometric entanglement entropy following a local quench in the D1D5 conformal field theory, a two-dimensional theory that describes a particular b…
Evidence for fast thermalization in the plane-wave matrix model
Curtis T. Asplund, David Berenstein, Diego Trancanelli
We perform a numerical simulation of the classical evolution of the plane-wave matrix model with semiclassical initial conditions. Some of these initial conditions thermalize and a…
Non-adiabaticity and improved back-reaction
Curtis T. Asplund, David Berenstein
We treat quantum back-reaction in time dependent processes for quantum field theory in various simplified models. The first example is a harmonic oscillator whose frequency depends…
Small AdS black holes from SYM
Curtis T. Asplund, David Berenstein
We provide a characterization of the set of configurations in N=4 SYM theory that are dual to small AdS black holes. Our construction shows that the black hole dual states are appr…
Deflection of Pulsar Signal Reveals Compact Structures in the Galaxy
Alex S. Hill, Daniel R. Stinebring, Curtis T. Asplund +3
We have detected a strong deflection of radio waves from the pulsar PSR B0834+06 in scintillation observations. Interference between the undeflected pulsar image and deflected subi…
