Topological wave structures—phase vortices, skyrmions, merons, etc.—are attracting
enormous attention in a variety of quantum and classical wave fields. Surprisingly, these …

Physics of structured waves is currently limited to relatively small particle energies as the
available generation techniques are only applicable to the soft X-ray twisted photons, to the …

We present a 48-element programmable phase plate for coherent electron waves produced
by a combination of photolithography and focused ion beam. This brings the highly …

By means of numerical simulations, we demonstrate the innovative use of computational
ghost imaging in transmission electron microscopy to retrieve images with a resolution that …

In this work, the paraxial approximation of the free Dirac equation is examined. The results
are first obtained by constructing superpositions of exact solutions with suitable profiles …

The generation of small electron probes is the basis for various techniques in which such a
probe is scanned across a sample, and special probe shapes like vortices can be desirable …

Electron vortex beams (EVBs, also known as twisted electron beams) possess an intrinsic
orbital angular momentum (OAM) with respect to their propagation direction. This intrinsic …

We present a theoretical description of charged particles with nonzero projection of the
orbital angular momentum (OAM) in a uniform magnetic field with broken axial symmetry …

光子, 电子及其他粒子的涡旋(扭曲) 态指这些粒子相应的波函数呈螺旋状波前的非平面波解.
这些涡旋态在沿着平均传播方向上携带内禀轨道角动量, 这一特性使得它们的波函数具有螺旋形 …

Transmission electron microscopy (TEM) is a technique that uses an electron beam to
analyze materials. This analysis is based on the interaction between the electron beam and …
