One-dimensional disordered quantum mechanics and Sinai diffusion with random absorbers [PDF]
, 2013 We study the one-dimensional Schr\"odinger equation with a disordered potential of the form $V (x) = \phi(x)^2+\phi'(x) + \kappa(x) $ where $\phi(x)$ is a Gaussian white noise with mean $\mu g$ and variance $g$, and $\kappa(x)$ is a random superposition ...

On multi-index Whittaker function, related integrals and inequalities
Journal of Mathematical Inequalities, 2022 . A new generalization of Whittaker function M λ , µ ( z ) is introduced and studied by means of the extended multi-index confluent hypergeometric function of the first kind Φ ( γ i ) , p ( α i , β i ) introduced in [1].

Radio-Optical Galaxy Shape Correlations in the COSMOS Field [PDF]
, 2016 We investigate the correlations in galaxy shapes between optical and radio wavelengths using archival observations of the COSMOS field. Cross-correlation studies between different wavebands will become increasingly important for precision cosmology as ...

Difference Sturm--Liouville problems in the imaginary direction
, 2011 We consider difference operators in $L^2$ on $\R$ of the form $$ L f(s)=p(s)f(s+i)+q(s) f(s)+r(s) f(s-i) ,$$ where $i$ is the imaginary unit. The domain of definiteness are functions holomorphic in a strip with some conditions of decreasing at infinity ...

Propagation analysis of Whittaker–Gaussian laser beam in a gradient-index medium
Optical and quantum electronics, 2023 In this paper, the propagation of Whittaker–Gaussian beam passing through a gradient-index (GRIN) medium is studied. Based on the extended Huygens–Fresnel diffraction integral, the analytical expression of the intensity distribution for the resulting ...

, 2018 We address evolution of a spinor polariton condensate in radially periodic potentials. Such potentials allow for the observation of novel nonlinear excitations and support a variety of dynamically stable soliton states never demonstrated before in ...

Journal of the Association for Information Science and Technology, EarlyView.Abstract This research explored how young adults (ages 18–25) learn to use financial records and the roles financial records play in their experiences in coming to see themselves as financially mature social actors. The contribution of this paper is a revised model of transitions theory that includes personal information management (PIM) as an ...

Abelian theorems in the framework of the distributional index Whittaker transform
Mathematical Communications, 2022 Summary: Our aim is to derive the abelian theorems for the index Whittaker transform over distributions of compact support and over certain function spaces of generalized functions.

British Educational Research Journal, EarlyView.Abstract This paper explores the challenges and opportunities surrounding the recruitment and retention of minority ethnic teachers in England. Drawing on interview data from 33 teachers and school leaders of diverse ethnic backgrounds, it investigates whether racialised barriers identified in earlier research have shifted in the current context of ...

Green functions of electrons in monolayer and bilayer graphene in a magnetic field
, 2011 Closed expressions for the Green functions of the stationary two-dimensional two-component Schrodinger equation for an electron moving in monolayer and bilayer graphene in the presence of a magnetic field are obtained in terms of the Whittaker functions ...
