Ubiquitous quantum scarring does not prevent ergodicity
Nature Communications, 2021 It is generally believed that most eigenstates of quantum chaotic models are ergodic. In this work, the authors disprove this by showing that all eigenstates of the Dicke model in the chaotic regime are scarred, and that ergodicity is an ensemble ...

Non-ergodicity in the Anisotropic Dicke model [PDF]
, 2017 We study the ergodic -- non-ergodic transition in a generalized Dicke model with independent co- and counter rotating light-matter coupling terms. By studying level statistics, the average ratio of consecutive level spacings, and the quantum butterfly ...

Discrete-Time Ergodic Mean-Field Games with Average Reward on Compact Spaces
Dynamic Games and Applications, 2019 We present a model of discrete-time mean-field game with compact state and action spaces and average reward. Under some strong ergodicity assumption, we show it possesses a stationary mean-field equilibrium.

The averaging principle for stochastic differential equations driven by a Wiener process revisited
Comptes Rendus. Mathématique, 2022 We consider a one-dimensional stochastic differential equation driven by a Wiener process, where the diffusion coefficient depends on an ergodic fast process.

Ergodic behavior of control and mean field games problems depending on acceleration [PDF]
, 2020 The goal of this paper is to study the long time behavior of solutions of the first-order mean field game (MFG) systems with a control on the acceleration.

Quenched limit theorems for expanding on average cocycles [PDF]
Stochastics and Dynamics, 2021 We prove quenched versions of a central limit theorem, a large deviations principle as well as a local central limit theorem for expanding on average cocycles.

SVD-based IWFA for next generation wireless MIMO communication
ICT Express, 2018 Point-to-point MIMO systems without channel state information at the transmitter (No CSIT) and with perfect channel state information at the transmitter (Perfect CSIT) were considered for the application of a novel singular-value-decomposition-based (SVD-

Ergodic optimization in dynamical systems [PDF]
Ergodic Theory and Dynamical Systems, 2017 Ergodic optimization is the study of problems relating to maximizing orbits and invariant measures, and maximum ergodic averages. An orbit of a dynamical system is called $f$ -maximizing if the time average of the real-valued function $f$ along the orbit

Average behaviour in discrete-time imprecise Markov chains: A study of weak ergodicity [PDF]
International Journal of Approximate Reasoning, 2021 We study the limit behaviour of upper and lower bounds on expected time averages in imprecise Markov chains; a generalised type of Markov chain where the local dynamics, traditionally characterised by transition probabilities, are now represented by sets
