Three-dimensional Quantum Slit Diffraction and Diffraction in Time [PDF]

open access: yes, 2014
We study the quantum slit diffraction problem in three dimensions. In the treatment of diffraction of particles by a slit, it is usually assumed that the motion perpendicular to the slit is classical.

High-throughput electron diffraction in the XtaLAB Synergy-ED [PDF]

open access: yesStructural Dynamics
Microcrystal electron diffraction (MicroED/3D ED), which solves atomic structures from crystals in the sub-micron size range using electron radiation, has evolved from an exploratory technique into a cutting-edge analytical method practiced in ...

A Method for Reducing Transcendental Dispersion Relations to Nonlinear Ordinary Differential Equations in a Wide Class of Wave Propagation Problems

open access: yesMathematics, 2022
A class of problems of wave propagation in waveguides consisting of one or several layers that are characterized by linear variation of the squared refractive index along the normal to the interfaces between them is considered in this paper.

Provenance Illusions and Elusive Paradata: When Archaeology and Art/Archaeological Practice Meets the Phygital

open access: yesOpen Archaeology, 2021
In this art/archaeological study, we question the utility of the interrelated concepts of provenance, provenience, and paradata as applied to assemblages in art, archaeology, and cultural heritage contexts.
