Tuning quantum magic of pure quantum chaotic states with a gravity dual
Antonio M. GarcÃa-GarcÃa, Xianlong Liu, Jie-ping Zheng
Quantum magic is a fundamental resource that quantifies to what extent quantum states can be efficiently simulated on a classical computer. We study it for states constructed from…
Many-Body Quantum Chaos At All Time Scales
Antonio M. GarcÃa-GarcÃa, Lucas Sá, Jacobus J. M. Verbaarschot +1
We describe the dynamics of many-body quantum chaotic systems at all time scales by studying the Green's and out-of-time order correlation (OTOC) functions of the four-body, -Ma…
Inducing, and enhancing, many-body quantum chaos by continuous monitoring
Xianlong Liu, Jie-ping Zheng, Antonio M. GarcÃa-GarcÃa
It is intuitively expected, and supported by earlier studies, that many-body quantum chaos is suppressed, or even destroyed, by dissipative effects induced by continuous monitoring…
Role of exceptional points in the dynamics of the Lindblad Sachdev-Ye-Kitaev model
Jie-ping Zheng, Jorge Dukelsky, Rafael A. Molina +1
The out of equilibrium dynamics of the Sachdev-Ye-Kitaev model (SYK), comprising Majoranas with random all-to-all four-body interactions, minimally coupled to a Markovian bath…
