Decoherence and Microscopic Diffusion at SYK
Javier M. Magan
Sachdev-Ye-Kitaev (SYK) or embedded random ensembles are models of fermions with random k-body interactions. They play an important role in understanding black hole dynamics, q…
Entanglement Entropy of Periodic Sublattices
Temple He, Javier M. Magan, Stefan Vandoren
We study the entanglement entropy (EE) of Gaussian systems on a lattice with periodic boundary conditions, both in the vacuum and at nonzero temperatures. By restricting the reduce…
Black hole collapse and democratic models
Aron Jansen, Javier M. Magan
We study the evolution of black hole entropy and temperature in collapse scenarios, finding three generic lessons. First, entropy evolution is extensive. Second, at large times, en…
Black holes as random particles: entanglement dynamics in infinite range and matrix models
Javier M. Magan
We first propose and study a quantum toy model of black hole dynamics. The model is unitary, displays quantum thermalization, and the Hamiltonian couples every oscillator with ever…
