Driven by applications in chemical sensing, biological imaging and material
characterisation, Raman spectroscopies are attracting growing interest from a variety of …

Atomtronics deals with matter-wave circuits of ultracold atoms manipulated through
magnetic or laser-generated guides with different shapes and intensities. In this way, new …

Structured light refers to the generation and application of custom light fields. As the tools
and technology to create and detect structured light have evolved, steadily the applications …

Photons can carry angular momentum, not only due to their spin, but also due to their spatial
structure. This extra twist has been used, for example, to drive circular motion of microscopic …

Both classical and quantum waves can form vortices: entities with helical phase fronts and
circulating current densities. These features determine the intrinsic orbital angular …

When a neutral atom moves in a properly designed laser field, its center-of-mass motion
may mimic the dynamics of a charged particle in a magnetic field, with the emergence of a …

As they travel through space, some light beams rotate. Such light beams have angular
momentum. There are two particularly important ways in which a light beam can rotate: if …

Chiral interactions are prevalent in nature, driving a variety of biochemical processes.
Discerning the two non-superimposable mirror images of a chiral molecule, known as …

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 …

Neutral atomic Bose condensates and degenerate Fermi gases have been used to realize
important many-body phenomena in their most simple and essential forms,,, without many of …
