Tuning quantum magic of pure quantum chaotic states with a gravity dual
Antonio M. García-García, 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. García-García, 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. García-García
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…
The Lyapunov exponent as a signature of dissipative many-body quantum chaos
Antonio M. García-García, Jacobus J. M. Verbaarschot, Jie-ping Zheng
A distinct feature of Hermitian quantum chaotic dynamics is the exponential increase of certain out-of-time-order-correlation (OTOC) functions around the Ehrenfest time with a rate…
Keldysh Wormholes and Anomalous Relaxation in the Dissipative Sachdev-Ye-Kitaev Model
Antonio M. García-García, Lucas Sá, Jacobus J. M. Verbaarschot +1
We study the out-of-equilibrium dynamics of a Sachdev-Ye-Kitaev (SYK) model, fermions with a -body interaction of infinite range, coupled to a Markovian environment. Close t…
Euclidean-to-Lorentzian wormhole transition and gravitational symmetry breaking in the Sachdev-Ye-Kitaev model
Antonio M. García-García, Victor Godet, Can Yin +1
We study a two-site Sachdev-Ye-Kitaev model with complex couplings and a weak inter-site interaction. At low temperatures, the system is dual to a Euclidean wormhole in Jackiw-Teit…
Phase diagram of a two-site coupled complex Sachdev-Ye-Kitaev model
Antonio M. García-García, Jie Ping Zheng, Vaios Ziogas
We study the thermodynamic properties of a two-site coupled complex Sachdev-Ye-Kitaev (SYK) model in the large limit by solving the saddle-point Schwinger-Dyson (SD) equations.…
Higher-dimensional charged black holes cannot be over-charged by gedanken experiments
Boxuan Ge, Yuyu Mo, Suting Zhao +1
We reconsider over-charging the higher-dimensional nearly extremal charged black holes using the new version of gedanken experiment proposed recently by Sorce and Wald. As a result…
