Quasiparticle kinetic theory for Calogero models
Vir B. Bulchandani, Manas Kulkarni, Joel E. Moore +1
We show that the quasiparticle kinetic theory for quantum and classical Calogero models reduces to the free-streaming Boltzmann equation. We reconcile this simple emergent behaviou…
A statistical mechanism for operator growth
Xiangyu Cao
It was recently conjectured that in generic quantum many-body systems, the spectral density of local operators has the slowest high-frequency decay as permitted by locality. We sho…
Origin and Limit of the Recovery of Damaged Information by Time Reversal
Xiangyu Cao, Thomas Scaffidi
Recently it was found that scrambled information can be partially recovered by a time-reversed evolution, even after being damaged by an intruder. We reconsider the origin of the i…
Dirac Fast Scramblers
Jaewon Kim, Ehud Altman, Xiangyu Cao
We introduce a family of Gross-Neveu-Yukawa models with a large number of fermion and boson flavors as higher dimensional generalizations of the Sachdev-Ye-Kitaev model. The models…
Scrambling versus relaxation in Fermi and non-Fermi liquids
Jaewon Kim, Xiangyu Cao, Ehud Altman
We compute the Lyapunov exponent characterizing quantum scrambling in a family of generalized Sachdev-Ye-Kitaev models, which can be tuned between different low temperature states…
Comment on "Chaotic-Integrable Transition in the Sachdev-Ye-Kitaev Model"
Jaewon Kim, Xiangyu Cao
In arXiv:1707.02197, the authors considered the Sachdev-Ye-Kitaev model with quadratic perturbation (also known as mass-deformed SYK), and claimed that the quantum Lyapunov exponen…
