Multi‐Slit Diffraction in Scaled Space‐Time

open access: yesNatural Sciences, EarlyView.
A space‐time scaling is used to transform quantum wave packets describing free particle motion to packets moving in an effective harmonic oscillator potential that confines and directs the wave fronts along the classical phase space of the oscillator. The transformation is applied to multi‐slit diffraction and shown to characterize diffraction features

Higher-Order Hermite-Fejér Interpolation for Stieltjes Polynomials

open access: yesJournal of Applied Mathematics, 2013
Let and be the ultraspherical polynomials with respect to . Then, we denote the Stieltjes polynomials with respect to satisfying . In this paper, we consider the higher-order Hermite-Fejér interpolation operator based on the zeros of and the higher

On the complex Hermite polynomials

open access: yesFilomat, 2020
In this paper we use a set of partial differential equations to prove an expansion theorem for multiple complex Hermite polynomials. This expansion theorem allows us to develop a systematic and completely new approach to the complex Hermite polynomials.

Quantum Ghost Imaging by Sparse Spatial Mode Reconstruction

open access: yesAdvanced Quantum Technologies, EarlyView.
Hermite–Gaussian spatial modes are used in quantum ghost imaging for enhanced image reconstruction, by exploiting modal sparsity. By leveraging structured light as a basis for imaging, time‐efficient and high resolution quantum ghost imaging is achieved, paving the way for breakthroughs in low‐light, biological science applications.

Efficient Simulation of Open Quantum Systems on NISQ Trapped‐Ion Hardware

open access: yesAdvanced Quantum Technologies, EarlyView.
Open quantum systems exhibit rich dynamics that can be simulated efficiently on quantum computers, allowing us to learn more about their behavior. This work applies a new method to simulate certain open quantum systems on noisy trapped‐ion quantum hardware.

Distance sampling: comparing walked transects and road transects for rock ptarmigan densities and population trends

open access: yesWildlife Biology, EarlyView.
We compared population trends for rock ptarmigan Lagopus muta densities (2003‒2019) derived from walked transects and driven road transects in Mosfellsheiði and Slétta in southwest and northeast Iceland, respectively. The walked transects were laid out according to a random rule.

A generalization of Hermite polynomials [PDF]

open access: yesInternational Journal of Contemporary Mathematical Sciences, 2014
In this paper, we introduce a simple set   ( ) p n H x , which is a generalized form of Hermite polynomial ( ) n H x . We establish series form, basic recurrence relations, the pure recurrence relation and Rodrigues type formula for the generalized polynomial.

The Spectral Connection Matrix for Any Change of Basis within the Classical Real Orthogonal Polynomials

open access: yesMathematics, 2015
The connection problem for orthogonal polynomials is, given a polynomial expressed in the basis of one set of orthogonal polynomials, computing the coefficients with respect to a different set of orthogonal polynomials.
