Phase transition in a doubly holographic model of closed spacetime
Wen-Hao Jiang, Cheng Peng, Yun-Song Piao
Double holography has been proved to be a powerful method in comprehending the spacetime entanglement. In this paper we investigate the doubly holographic construction in ${\mathrm…
Gauging the complex SYK model
Ziruo Zhang, Cheng Peng
Motivated by SYK-like models describing near-BPS black holes in string/M-theory, we consider gauging the U symmetry of the complex SYK model in the presence of a Wilson line w…
D-commuting SYK model: building quantum chaos from integrable blocks
Ping Gao, Han Lin, Cheng Peng
We construct a new family of quantum chaotic models by combining multiple copies of integrable commuting SYK models. As each copy of the commuting SYK model does not commute with o…
Half-Wormholes and Ensemble Averages
Cheng Peng, Jia Tian, Yingyu Yang
We study "half-wormhole-like" saddle point contributions to spectral correlators in a variety of ensemble average models, including various statistical models, generalized 0d SYK m…
