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.

The quantum Arnold transformation [PDF]

open access: yes, 2010
By a quantum version of the Arnold transformation of classical mechanics, all quantum dynamical systems whose classical equations of motion are non-homogeneous linear second-order ordinary differential equations, including systems with friction linear in

Short distance modification of the quantum virial theorem

open access: yesPhysics Letters B, 2017
In this letter, we will analyse the deformation of a semi-classical gravitational system from minimal measurable length scale. In the semi-classical approximation, the gravitational field will be analysed as a classical field, and the matter fields will ...

Effects of Newtonian gravitational self-interaction in harmonically trapped quantum systems [PDF]

open access: yes, 2015
The Schr\"odinger-Newton equation has gained attention in the recent past as a nonlinear modification of the Schr\"odinger equation due to a gravitational self-interaction.

Eulerian and Newtonian dynamics of quantum particles [PDF]

open access: yes, 2013
We derive the classical equations of hydrodynamic type (Euler equation and the continuity equation) from which the Schrodinger equation follows as a limit case.

Nonlinear interfaces: intrinsically nonparaxial regimes and effects [PDF]

open access: yes, 2009
The behaviour of optical solitons at planar nonlinear boundaries is a problem rich in intrinsically nonparaxial regimes that cannot be fully addressed by theories based on the nonlinear Schrödinger equation.
