Floquet theory for temporal correlations and spectra in time-periodic open quantum systems: Application to squeezed parametric oscillation beyond the rotating-wave approximation [PDF]

open access: yes, 2021
Open quantum systems can display periodic dynamics at the classical level either due to external periodic modulations or to self-pulsing phenomena typically following a Hopf bifurcation.

New exact solutions for the Khokhlov-Zabolotskaya-Kuznetsov, the Newell-Whitehead-Segel and the Rabinovich wave equations by using a new modification of the tanh-coth method

open access: yesCogent Mathematics, 2016
The family of the tangent hyperbolic function methods is one of the most powerful method to find the solutions of the nonlinear partial differential equations. In the mathematical literature, there are a great deal of tanh-methods completing each other.

Time-Frequency Integrals and the Stationary Phase Method in Problems of Waves Propagation from Moving Sources [PDF]

open access: yes, 2012
The time-frequency integrals and the two-dimensional stationary phase method are applied to study the electromagnetic waves radiated by moving modulated sources in dispersive media. We show that such unified approach leads to explicit expressions for the

A Survey on Continuous Time Computations [PDF]

open access: yes, 2007
We provide an overview of theories of continuous time computation. These theories allow us to understand both the hardness of questions related to continuous time dynamical systems and the computational power of continuous time analog models.

Unification of all hyperbolic tangent function methods

open access: yesOpen Physics, 2016
Over the last twenty years, several “different” hyperbolic tangent function methods have been proposed to search solutions for nonlinear partial differential equations (NPDEs).

Boundary integral equations on unbounded rough surfaces: Fredholmness and the finite section method [PDF]

open access: yes, 2008
We consider a class of boundary integral equations that arise in the study of strongly elliptic BVPs in unbounded domains of the form $D = \{(x, z)\in \mathbb{R}^{n+1} : x\in \mathbb{R}^n, z > f(x)\}$ where $f : \mathbb{R}^n \to\mathbb{R}$ is a ...

Dynamical principles in neuroscience [PDF]

open access: yes, 2006
Dynamical modeling of neural systems and brain functions has a history of success over the last half century. This includes, for example, the explanation and prediction of some features of neural rhythmic behaviors.

Limit operators, collective compactness, and the spectral theory of infinite matrices [PDF]

open access: yes, 2010
In the first half of this memoir we explore the interrelationships between the abstract theory of limit operators (see e.g. the recent monographs of Rabinovich, Roch and Silbermann (2004) and Lindner (2006)) and the concepts and results of the ...

Noise, transient dynamics, and the generation of realistic interspike interval variation in square-wave burster neurons

open access: yes, 2014
First return maps of interspike intervals for biological neurons that generate repetitive bursts of impulses can display stereotyped structures (neuronal signatures).

The Inverse Grating Problem: Efficient Design of Anomalous Flexural Wave Reflectors and Refractors

open access: yes, 2019
We present an extensive formulation of the inverse grating problem for exural waves, in which the energy of each diffracted mode is selected and the grating configuration is then obtained by solving a linear system of equations.
