From integrability to many-body quantum chaos through a Markovian bath
Xianlong Liu, Antonio M. García-García
Recent examples have confirmed the common belief that quantum chaos is always suppressed in the presence of an environment. Here we show that this is not always the case. We comput…
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…
Entanglement transitions and multifractality in monitored free-fermions with random long-range hopping
Bo Fan, Antonio M. García-García
We study the entanglement dynamics of a one-dimensional chain of monitored non-interacting complex fermions with random power-law hopping characterized by a decay exponent . For…
No measurement induced phase transition in the entanglement dynamics of monitored non-interacting one-dimensional fermions in a disordered or quasiperiodic potential
Can Yin, Bo Fan, Antonio M. García-García
We show that the entanglement entropy (EE) of one-dimensional (1d) non-interacting fermions with symmetry in the presence of a disordered or quasi-periodic potential in whic…
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…
Entanglement dynamics of monitored noninteracting fermions on graphics processing units
Bo Fan, Can Yin, Antonio M. García-García
The description of the entanglement dynamics of monitored noninteracting fermions, including the existence of measurement-induced phase transitions (MIPTs), is a challenging proble…
Destruction and recovery of the entanglement entropy of a many-body quantum system after a single measurement
Bo Fan, Can Yin, Antonio M. García-García
For one-dimensional non-interacting complex fermions, we compute numerically the probability distribution of the change in the entanglement entropy (EE) after saturation, resulting…
Lindblad many-body scars
Antonio M. García-García, Zhongling Lu, Lucas Sá +1
Quantum many-body scars have received much recent attention for being both intriguing non-ergodic states in otherwise quantum chaotic systems and promising candidates to encode qua…
