Fractional integral associated with the Schrödinger operators on variable exponent space

open access: yesElectronic Research Archive, 2023
Let $ \mathcal{L} = -\Delta+V $ be the Schrödinger operators on $ \mathbb{R}^n $ with nonnegative potential $ V $ belonging to the reverse Hölder class $ RH_q $ for some $ q \geq \frac{n}{2} $.

Euclidean operator radius inequalities of $d$-tuple operators and operator matrices [PDF]

open access: yesarXiv, 2023
In this paper, we develop several Euclidean operator radius inequalities of $d$-tuple operators, as well as the sum and the product of $d$-tuple operators. Also, we obtain a power inequality for the Euclidean operator radius. Further, we develop Euclidean operator radius inequalities of $2\times 2$ operator matrices whose entries are $d$-tuple ...

Strong Coupling Asymptotics for a Singular Schrödinger Operator with an Interaction Supported by an Open Arc [PDF]

open access: yes, 2012
We consider a singular Schrödinger operator in L 2(ℝ2) written formally as − Δ − βδ(x − γ) where γ is a C 4 smooth open arc in ℝ2 of length L with regular ends.

The Boundedness of Marcinkiewicz Integrals Associated with Schrödinger Operator on Morrey Spaces

open access: yesJournal of Function Spaces, 2014
Let L=-Δ+V be a Schrödinger operator, where V belongs to some reverse Hölder class. The authors establish the boundedness of Marcinkiewicz integrals associated with Schrödinger operators and their commutators on Morrey spaces.

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

On the Definition of Chirality and Enantioselective Fields

open access: yesIsrael Journal of Chemistry, Volume 62, Issue 11-12, December 2022., 2022
Abstract In solid state physics, any symmetry breaking is known to be associated with emergence of an order parameter. However, the order parameter for molecular and crystal chirality, which is a consequence of parity and mirror symmetry breaking, has not been known since its discovery.

Wannier functions and discrete NLS equations for nematicons

open access: yesMathematics in Engineering, 2019
We derive nonlocal discrete nonlinear Schrödinger (DNLS) equations for laser beam propagation in optical waveguide arrays that use a nematic liquid crystal substrate.

A note on the discrete Schrödinger operator with a perturbed periodic potential [PDF]

open access: yesOpuscula Mathematica, 2010
The aim of this paper is to study the spectrum of the one-dimensional discrete Schrödinger operator with a perturbed periodic potential. We obtain natural conditions under which this perturbation preserves the essential spectrum of the considered ...

Green functions on product networks [PDF]

open access: yes, 2018
We aim here at determining the Green function for general Schrödinger operators on product networks. The first step consists in expressing Schrödinger operators on a product network as sum of appropriate Schrödinger operators on each factor network ...

Subharmonic functions in scattering theory

open access: yesComptes Rendus. Mathématique, 2021
We present a method that uses the properties of subharmonic functions to control spatial asymptotics of Green’s kernel of multidimensional Schrödinger operator with rough potential.
