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…
Low-rank Sachdev-Ye-Kitaev models
Jaewon Kim, Xiangyu Cao, Ehud Altman
Motivated by recent works on atom-cavity realizations of fast scramblers, and on Cooper pairing in non-Fermi liquids, we study a family of solvable variants of the () Sachdev-…
Super-directional light emission and emission reversal from micro cavity arrays
Jakob Kreismann, Jaewon Kim, Martí Bosch +3
Optical microdisk cavities with certain asymmetric shapes are known to possess unidirectional far-field emission properties. Here, we investigate arrays of these dielectric microre…
Symmetry Breaking in Coupled SYK or Tensor Models
Jaewon Kim, Igor R. Klebanov, Grigory Tarnopolsky +1
We study a large tensor model with symmetry containing two flavors of Majorana fermions, and . We also study its random counterpart consisting o…
