Lindbladian dissipation of strongly-correlated quantum matter
Lucas Sá, Pedro Ribeiro, Tomaž Prosen
We propose the Sachdev-Ye-Kitaev Lindbladian as a paradigmatic solvable model of dissipative many-body quantum chaos. It describes strongly coupled Majorana fermions with rando…
Symmetry Classification and Universality in Non-Hermitian Many-Body Quantum Chaos by the Sachdev-Ye-Kitaev Model
Antonio M. García-García, Lucas Sá, Jacobus J. M. Verbaarschot
Spectral correlations are a powerful tool to study the dynamics of quantum many-body systems. For Hermitian Hamiltonians, quantum chaotic motion is related to random matrix theory…
-Laguerre spectral density and quantum chaos in the Wishart-Sachdev-Ye-Kitaev model
Lucas Sá, Antonio M. García-García
We study the Wishart-Sachdev-Ye-Kitaev (WSYK) model consisting of two -body Sachdev-Ye-Kitaev (SYK) models with general complex couplings, one the Hermitian conjugate of t…
Dissipation and decoherence for generic open quantum systems
Lucas Sá
We study generic open quantum systems with Markovian dissipation, focusing on a class of stochastic Liouvillian operators of Lindblad form with independent random dissipation chann…
Complex Spacing Ratios: A Signature of Dissipative Quantum Chaos
Lucas Sá, Pedro Ribeiro, Tomaž Prosen
We introduce a complex-plane generalization of the consecutive level-spacing distribution, used to distinguish regular from chaotic quantum spectra. Our approach features the distr…
Self-focusing of multiple interacting Laguerre-Gauss beams in Kerr media
Lucas Sá, Jorge Vieira
Using a variational approach, we obtain the self-focusing critical power for a single and for any number of interacting Laguerre-Gauss beams propagating in a Kerr nonlinear optical…
Spectral and Steady-State Properties of Random Liouvillians
Lucas Sá, Pedro Ribeiro, Tomaž Prosen
We study generic open quantum systems with Markovian dissipation, focusing on a class of stochastic Liouvillian operators of Lindblad form with independent random dissipation chann…
