Beyond the Boltzmann equation for weakly coupled quantum fields
Xu-Yao Hu, Vladimir Rosenhaus
We study the kinetic theory of a weakly interacting quantum field. Assuming a state that is close to homogeneous and stationary, we derive a closed kinetic equation for the rate of…
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…
Random coupling model of turbulence as a classical Sachdev-Ye-Kitaev model
Xu-Yao Hu, Vladimir Rosenhaus
We point out that a classical analog of the Sachdev-Ye-Kitaev model -- a solvable model of quantum many-body chaos, was studied long ago in the turbulence literature. Motivated by…
Correlation functions in linear chaotic maps
Xu-Yao Hu, Vladimir Rosenhaus
The simplest examples of chaotic maps are linear, area-preserving maps on the circle, torus, or product of tori; respectively known as the Bernoulli map, the cat map, and the recen…
Electric Field Decay Without Pair Production: Lattice, Bosonization and Novel Worldline Instantons
Xu-Yao Hu, Matthew Kleban, Cedric Yu
Electric fields can spontaneously decay via the Schwinger effect, the nucleation of a charged particle-anti particle pair separated by a critical distance . What happens if the…
