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…
Robustness of quantum chaos and anomalous relaxation in open quantum circuits
Takato Yoshimura, Lucas Sá
Dissipation is a ubiquitous phenomenon that affects the fate of chaotic quantum many-body dynamics. Here, we show that chaos can be robust against dissipation but can also assist a…
Signatures of dissipative quantum chaos
Lucas Sá
Understanding the far-from-equilibrium dynamics of dissipative quantum systems, where dissipation and decoherence coexist with unitary dynamics, is an enormous challenge with immen…
Toward a classification of PT-symmetric quantum systems: From dissipative dynamics to topology and wormholes
Antonio M. García-García, Lucas Sá, Jacobus J. M. Verbaarschot +1
Studies of many-body non-Hermitian parity-time (PT)-symmetric quantum systems are attracting a lot of interest due to their relevance in research areas ranging from quantum optics…
Sixfold Way of Traversable Wormholes in the Sachdev-Ye-Kitaev Model
Antonio M. García-García, Lucas Sá, Jacobus J. M. Verbaarschot +1
In the infrared limit, a nearly anti-de Sitter spacetime in two dimensions (AdS) perturbed by a weak double trace deformation and a two-site -body Sachdev-Ye-Kitaev (SYK…
Symmetry Classification of Many-Body Lindbladians: Tenfold Way and Beyond
Lucas Sá, Pedro Ribeiro, Tomaž Prosen
We perform a systematic symmetry classification of many-body Lindblad superoperators describing general (interacting) open quantum systems coupled to a Markovian environment. Our c…
Universality and its limits in non-Hermitian many-body quantum chaos using the Sachdev-Ye-Kitaev model
Antonio M. García-García, Lucas Sá, Jacobus J. M. Verbaarschot
Spectral rigidity in Hermitian quantum chaotic systems signals the presence of dynamical universal features at timescales that can be much shorter than the Heisenberg time. We stud…
Spectral and steady-state properties of fermionic random quadratic Liouvillians
João Costa, Pedro Ribeiro, Andrea de Luca +2
We study spectral and steady-state properties of generic Markovian dissipative systems described by quadratic fermionic Liouvillian operators of the Lindblad form. The Hamiltonian…
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…
