Onset of random-matrix statistics in the Yukawa-Sachdev-Ye-Kitaev model: Spectral correlations and Krylov complexity
Sizheng Cao, Hyun-Sik Jeong, Yi-Li Wang
The Yukawa-Sachdev-Ye-Kitaev (YSYK) model, a solvable model of non-Fermi liquids with a proposed cavity-QED realization, couples complex fermions to bosons of frequency $ω_…
Symmetry restoration in a fast scrambling system
Sizheng Cao, Xian-Hui Ge
Entanglement asymmetry -- used here as a direct probe of symmetry restoration -- provides a sharp diagnostic of post-quench dynamics. We test this idea in the complex Sachdev--Ye--…
Excitation Transmission through a non-Hermitian traversable wormhole
Sizheng Cao, Xian-Hui Ge
This study explores the intricate real-time dynamics of a non-Hermitian system composed of two interconnected Sachdev-Ye-Kitaev (SYK) models. A central finding reveals that an exci…
Matching partition functions of deformed JT gravity and the cSYK model
Jan C. Louw, Sizheng Cao, Xian-Hui Ge
Motivated by recent analogies between the large- cSYK model and charged black holes, we aim to find a concrete gravitation theory with a matching partition function. Our main fo…
Non-Hermitian quantum system generated from two coupled Sachdev-Ye-Kitaev models
Wenhe Cai, Sizheng Cao, Xian-Hui Ge +2
We show that a non-Hermitian two coupled Sachdev-Ye-Kitaev (SYK) model can provide thermodynamic structure equivalent to Hermitian two coupled SYK model. The energy spectrum, the e…
Thermodynamic and Real-time Dynamic Properties of Complex Sachdev-Ye-Kitaev Model
Sizheng Cao, Xian-Hui Ge, Yi-Cheng Rui
We study the complex Sachdev-Ye-Kitaev (cSYK) numerically and investigate thermodynamic behavior of cSYK model across varying chemical potentials. We discover that the cSYK model r…
