In the past decade modern societies have developed enormous communication and social
networks. Their classification and information retrieval processing has become a formidable …

Symmetry classification and universality in non-Hermitian many-body quantum chaos by the Sachdev-Ye-Kitaev model

AM García-García, L Sá, JJM Verbaarschot - Physical Review X, 2022 - APS
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 …

S Denisov, T Laptyeva, W Tarnowski, D Chruściński… - Physical review …, 2019 - APS
To understand the typical dynamics of an open quantum system in continuous time, we
introduce an ensemble of random Lindblad operators, which generate completely positive …

Generating random density matrices

K Życzkowski, KA Penson, I Nechita… - Journal of Mathematical …, 2011 - pubs.aip.org
We study various methods to generate ensembles of random density matrices of a fixed size
N, obtained by partial trace of pure states on composite systems. Structured ensembles of …

Quantum chaos and coherence: Random parametric quantum channels

AS Matsoukas-Roubeas, T Prosen, A del Campo - Quantum, 2024 - quantum-journal.org
The survival probability of an initial Coherent Gibbs State (CGS) is a natural extension of the
Spectral Form Factor (SFF) to open quantum systems. To quantify the interplay between …

Generating random quantum channels

R Kukulski, I Nechita, Ł Pawela, Z Puchała… - Journal of …, 2021 - pubs.aip.org
Several techniques of generating random quantum channels, which act on the set of d-
dimensional quantum states, are investigated. We present three approaches to the problem …

Random lindblad dynamics

T Can - Journal of Physics A: Mathematical and Theoretical, 2019 - iopscience.iop.org
We study the mixing behavior of random Lindblad generators with no symmetries, using the
dynamical map or propagator of the dissipative evolution. In particular, we determine the …

Random generators of Markovian evolution: A quantum-classical transition by superdecoherence

W Tarnowski, I Yusipov, T Laptyeva, S Denisov… - Physical Review E, 2021 - APS
Continuous-time Markovian evolution appears to be manifestly different in classical and
quantum worlds. We consider ensembles of random generators of N-dimensional Markovian …

Quantum nonstationary phenomena of spin systems in collision models

Y Li, X Li, J Jin - Physical Review A, 2023 - APS
We investigate the nonstationary phenomenon in a tripartite spin-1/2 system in the collision
model (CM) framework. After introducing the dissipation through the system-environment …

Spectral transitions and universal steady states in random Kraus maps and circuits

L Sá, P Ribeiro, T Can, T Prosen - Physical Review B, 2020 - APS
The study of dissipation and decoherence in generic open quantum systems recently led to
the investigation of spectral and steady-state properties of random Lindbladian dynamics. A …
