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…
Large Tensor and SYK Models
Jaewon Kim
The SYK model proposed by Sachdev, Ye, and Kitaev consists of Majorana fermions that interact randomly four at a time. The model develops a dense spectrum above the ground state, d…
Asymptotic Symmetries of Colored Gravity in Three Dimensions
Euihun Joung, Jaewon Kim, Jihun Kim +1
Three-dimensional colored gravity refers to nonabelian isospin extension of Einstein gravity. We investigate the asymptotic symmetry algebra of the -colored gravity in (2+1)…
Massless and Massive Higher Spins from Anti-de Sitter Space Waveguide
Seungho Gwak, Jaewon Kim, Soo-Jong Rey
Higgs mechanism to massive higher-spin gauge fields is an outstanding open problem. We investigate this issue in the context of Kaluza-Klein compactification. Starting from a free…
