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…
