Quasi-random numbers in some statistical systems
Lietuvos Matematikos Rinkinys, 2000 There are many ways to get random numbers. Some methods include making hardware devices that generate noise, observing cosmic ray flux and etc. Pseudo-random numbers come from mathematical functions and algorithms that provides such numbers called ...

Quantifying scrambling in quantum neural networks
Journal of High Energy Physics, 2022 We quantify the role of scrambling in quantum machine learning. We characterize a quantum neural network’s (QNNs) error in terms of the network’s scrambling properties via the out-of-time-ordered correlator (OTOC).

Chaos and high temperature pure state thermalization
Journal of High Energy Physics, 2019 Classical arguments for thermalization of isolated systems do not apply in a straightforward way to the quantum case. Recently, there has been interest in diagnostics of quantum chaos in many-body systems.

Random periodic solutions of random dynamical systems
Journal of Differential Equations, 2009 In this paper, we give the definition of the random periodic solutions of random dynamical systems. We prove the existence of such periodic solutions for a $C^1$ perfect cocycle on a cylinder using a random invariant set, the Lyapunov exponents and the pullback of the cocycle.

Hayden-Preskill decoding from noisy Hawking radiation
Journal of High Energy Physics, 2021 In the Hayden-Preskill thought experiment, the Hawking radiation emitted before a quantum state is thrown into the black hole is used along with the radiation collected later for the purpose of decoding the quantum state.

RANDOM DYNAMICAL SYSTEMS IN ECONOMICS [PDF]
Stochastics and Dynamics, 2001 This paper surveys recent advances in the application of random dynamical systems theory in economics. It illustrates the usefulness of this framework for modeling and analysis of economic phenomena with stochastic components, mainly focusing on stochastic dynamic models of economic growth.

Barren plateaus from learning scramblers with local cost functions
Journal of High Energy Physics, 2023 The existence of barren plateaus has recently revealed new training challenges in quantum machine learning (QML). Uncovering the mechanisms behind barren plateaus is essential in understanding the scope of problems that QML can efficiently tackle. Barren

, 2010 Abstract Real materials always contain randomness or disorder that cannot be expressed by idealized simple model systems. The present chapter studies the effects of randomness on phase transitions and critical phenomena. Although randomness may seem to obscure singular behaviour such as divergence of physical quantities at the critical ...

Effects of spatially nonuniform gain on lasing modes in weakly scattering random systems [PDF]
, 2009 A study on the effects of optical gain nonuniformly distributed in one-dimensional random systems is presented. It is demonstrated numerically that even without gain saturation and mode competition, the spatial nonuniformity of gain can cause dramatic ...
