The recent prediction and subsequent creation of electron vortex beams in a number of
laboratories occurred after almost 20 years had elapsed since the recognition of the physical …

Topological quantum computers promise a fault tolerant means to perform quantum
computation. Topological quantum computers use particles with exotic exchange statistics …

Free electrons can possess an intrinsic orbital angular momentum, similar to those in an
electron cloud, upon free-space propagation. The wave front corresponding to the electron's …

An electron vortex beam (EVB) carrying orbital angular momentum (OAM) plays a key role in
a series of fundamental scientific researches, such as chiral energy-loss spectroscopy and …

The Dzyaloshinskii-Moriya interaction in ultrathin ferromagnets can result in nonreciprocal
propagation of spin waves. We examine theoretically how spin wave power flow is …

Magnetic measurement by transmitted electrons at nanometer or even atomic scale is
always an attractive and challenging issue in the transmission electron microscope. Electron …

A model for a new electron-vortex beam production method is proposed and experimentally
demonstrated. The technique calls on the controlled manipulation of the degrees of freedom …

We experimentally realize higher-order catastrophic structures in light fields presenting
solutions of the paraxial diffraction catastrophe integral. They are determined by potential …

We suggested the hexagonal aperture to compute the point spread function (PSF) by
making use of scalar diffraction theory and Fourier operations. We have got an analytical …

The phase problem can be considered as one of the cornerstones of quantum mechanics
intimately connected to the detection process and the uncertainty relation. The latter impose …
