Structured waves are ubiquitous for all areas of wave physics, both classical and quantum, where the wavefields are inhomogeneous and cannot be approximated by a single plane wave. Even the interference of two plane waves, or of a single inhomogeneous (evanescent) wave, provides a number of nontrivial phenomena and additional functionalities as compared to a single plane wave. Complex wavefields with inhomogeneities in the amplitude, phase, and polarization, including topological structures and singularities, underpin modern nanooptics and photonics, yet they are equally important, e.g., for quantum matter waves, acoustics, water waves, etc. Structured waves are crucial in optical and electron microscopy, wave propagation and scattering, imaging, communications, quantum optics, topological and non-Hermitian wave systems, quantum condensed-matter systems, optomechanics, plasmonics and metamaterials, optical and acoustic manipulation, and so forth. This Roadmap is written collectively by prominent researchers and aims to survey the role of structured waves in various areas of wave physics. Providing background, current research, and anticipating future developments, it will be of interest to a wide cross-disciplinary audience.

The development of modern spintronics materials ushered the need for novel characterization tools capable of characterizing nanometer-sized spin textures. Neutrons are a convenient probe for this task due to their angstrom-sized wavelengths, electric neutrality and robustly controllable spin state. Recent research has focused on enabling access to new degrees of freedom in order to provide a neutron toolbox capable of characterizing emerging materials. This includes the development of tomography techniques for characterizing the 3D bulk spin textures and the techniques for creating neutron helical and skyrmion-like spin-orbit states. Here we provide a concise overview of this work and discuss future prospects and applications.

“…Nevertheless, only four such neutrons have been probably observed [6]. In [7], a more advanced and precise method of the generation of twisted neutrons has been developed and grating methods have also been used. Methods of producing twisted neutrons using special geometries of magnetic fields have been elaborated on in [8].…”

The use of a (quasi)uniform magnetic field opens new possibilities for a production of twisted particles having orbital angular momenta. We ascertain these possibilities. Quantum states suitable for a creation of charged particles in a uniform magnetic field are determined. The particle penetration from a solenoid to vacuum or another solenoid is analyzed in detail. It is shown that a previously proposed approach can be utilized for a successful production of twisted positrons and positroniums. We also find a new effect of increasing an uncertainty of phase of the particle rotation with the distance passed by the particle in the solenoid. This effect based on fundamentals of quantum mechanics leads to exciting new possibilities of production of twisted particles in real solenoids without additional particle sources therein.
