Modulated Harmonic Wave in Series‐Connected Discrete Josephson Transmission Line: The Discrete Calculus Approach

open access: yesphysica status solidi (b), Volume 260, Issue 1, January 2023., 2023
The modulated harmonic wave in the discrete series‐connected Josephson transmission line (JTL) is considered and the equation describing the modulation amplitude is obtained. The equation turns out to be the defocusing nonlinear Schrödinger equation. The most interesting result following the calculations is the existence of the dark solitons in the JTL.

Existence of global solutions to a quasilinear Schrödinger equation with general nonlinear optimal control conditions

open access: yesBoundary Value Problems, 2020
In this article, we study a modified maximum principle approach under condition on the weight of the delay term in the feedback and the weight of the term without delay.

Benefits of Open Quantum Systems for Quantum Machine Learning

open access: yesAdvanced Quantum Technologies, EarlyView., 2023
Quantum machine learning (QML), poised to transform data processing, faces challenges from environmental noise and dissipation. While traditional efforts seek to combat these hindrances, this perspective proposes harnessing them for potential advantages. Surprisingly, under certain conditions, noise and dissipation can benefit QML.

Analytic solutions of the chiral nonlinear schrödinger equations investigated by an efficient approach

open access: yesInternational Journal of Physical Research, 2019
This paper studies the chiral nonlinear Schrödinger equations, describing a central role in the developments of quantum me-chanics, particularly in the field of quantum Hall effect, where chiral excitations are known to appear. More precisely, in this paper, we acquired new exact solutions of the chiral nonlinear (1+1) and (1+2)-dimensional Schrà ...

Rogue waves on the double-periodic background in the focusing nonlinear Schrödinger equation. [PDF]

open access: yesPhysical Review E, 2019
The double-periodic solutions of the focusing nonlinear Schrödinger equation have been previously obtained by the method of separation of variables. We construct these solutions by using an algebraic method with two eigenvalues.

On ground states for the 2D Schrödinger equation with combined nonlinearities and harmonic potential

open access: yesStudies in Applied Mathematics, Volume 150, Issue 1, Page 92-118, January 2023., 2023
Abstract We consider the nonlinear Schrödinger equation with a harmonic potential in the presence of two combined energy‐subcritical power nonlinearities. We assume that the larger power is defocusing, and the smaller power is focusing. Such a framework includes physical models, and ensures that finite energy solutions are global in time.

Are physiological oscillations physiological?

open access: yesThe Journal of Physiology, EarlyView., 2023
Abstract figure legend Mechanisms and functions of physiological oscillations. Abstract Despite widespread and striking examples of physiological oscillations, their functional role is often unclear. Even glycolysis, the paradigm example of oscillatory biochemistry, has seen questions about its oscillatory function.

Study of Attractive Nonlinearity by 1-D Nonlinear Schrödinger Equation in the Bose–Einstein Condensate

open access: yesJournal of Bangladesh Academy of Sciences, 1970
The work represents and investigates the stationary solutions of the one-dimensional Non-linear Schrödinger Equation (NLSE), for attractive non-linearity, in the Bose-Einstein condensates (BEC) under the box boundary condition and calculates the characteristics of internal modes of bright solitons (eigen modes of small perturbation of the condensate ...
