Transmission and reflection studies of periodic and random systems with gain [PDF]

, 1999
The transmission ({ital T}) and reflection ({ital R}) coefficients are studied in periodic systems and random systems with gain. For both the periodic electronic tight-binding model and the periodic classical many-layered model, we obtain numerically and

Window measurements of simulations in random systems

, 2014
Numerical studies in random systems are plagued with strong finite-size effects and boundary effects. We introduce a window-measurement method as a practical solution to these difficulties.

Probing non-orthogonality of eigenvectors in non-Hermitian matrix models: diagrammatic approach

Journal of High Energy Physics, 2018
Using large N arguments, we propose a scheme for calculating the two-point eigenvector correlation function for non-normal random matrices in the large N limit. The setting generalizes the quaternionic extension of free probability to two-point functions.

Strong Griffiths singularities in random systems and their relation to extreme value statistics [PDF]

, 2006
We consider interacting many-particle systems with quenched disorder having strong Griffiths singularities, which are characterized by the dynamical exponent, $z$, such as random quantum systems and exclusion processes.

Exact solutions to chaotic and stochastic systems

, 2001
We investigate functions that are exact solutions to chaotic dynamical systems. A generalization of these functions can produce truly random numbers. For the first time, we present solutions to random maps.

On solving systems of random linear disequations [PDF]

, 2007
An important subcase of the hidden subgroup problem is equivalent to the shift problem over abelian groups. An efficient solution to the latter problem would serve as a building block of quantum hidden subgroup algorithms over solvable groups.

Fast-slow partially hyperbolic systems versus Freidlin-Wentzell random systems

, 2016
We consider a simple class of fast-slow partially hyperbolic dynamical systems and show that the (properly rescaled) behaviour of the slow variable is very close to a Friedlin--Wentzell type random system for times that are rather long, but much shorter ...

Upper semicontinuity of random attractors for non-compact random dynamical systems

Electronic Journal of Differential Equations, 2009
The upper semicontinuity of random attractors for non-compact random dynamical systems is proved when the union of all perturbed random attractors is precompact with probability one.

Generalized free cumulants for quantum chaotic systems

Journal of High Energy Physics
The eigenstate thermalization hypothesis (ETH) is the leading conjecture for the emergence of statistical mechanics in generic isolated quantum systems and is formulated in terms of the matrix elements of operators.

Reliability Assessment of Random Uncertain Multi-State Systems

IEEE Access, 2019
The random uncertain multi-state system is defined as a multi-state system consisting of multi-state components whose performance rates and the corresponding state probabilities are presented as uncertain variables. Reliability assessment of random multi-
