Quantum gravity of the Heisenberg algebra
Ahmed Almheiri, Akash Goel, Xu-Yao Hu
We consider a simplified model of double scaled SYK (DSSYK) in which the Hamiltonian is the position operator of the Harmonic oscillator. This model captures the high temperature l…
Semiclassical geometry in double-scaled SYK
Akash Goel, Vladimir Narovlansky, Herman Verlinde
We argue that at finite energies, double-scaled SYK has a semiclassical approximation controlled by a coupling in which all observables are governed by a non-trivial saddle poi…
Towards a String Dual of SYK
Akash Goel, Herman Verlinde
We propose a paradigm for realizing the SYK model within string theory. Using the large matrix description of string theory, we show that the effective theory on a large…
Classifying boundary conditions in JT gravity: from energy-branes to -branes
Akash Goel, Luca V. Iliesiu, Jorrit Kruthoff +1
We classify the possible boundary conditions in JT gravity and discuss their exact quantization. Each boundary condition that we study will reveal new features in JT gravity relate…
Expanding the Black Hole Interior: Partially Entangled Thermal States in SYK
Akash Goel, Ho Tat Lam, Gustavo J. Turiaci +1
We introduce a family of partially entangled thermal states in the SYK model that interpolates between the thermo-field double state and a pure (product) state. The states are prep…
Quantum Cosmology in Four Dimensions
Teresa Bautista, André Benevides, Atish Dabholkar +1
We analyze the cosmological solutions to the recently proposed nonlocal quantum effective action for gravity with a cosmological term. We show that the vacuum energy decays with a…
