Light–matter interaction in 2D and topological materials provides a fascinating control knob
for inducing emergent, non-equilibrium properties and achieving new functionalities in the …

Spin–orbit coupling induces a unique form of Zeeman interaction in momentum space in
materials that lack inversion symmetry: the electron's spin is locked on an effective magnetic …

Optoelectronic effects differentiating absorption of right and left circularly polarized photons
in thin films of chiral materials are typically prohibitively small for their direct photocurrent …

The importance of global band topology is unequivocally recognized in condensed matter
physics, and new states of matter, such as topological insulators, have been discovered …

The photoexcitation life cycle from incident photon (and creation of photoexcited electron–
hole pair) to ultimate extraction of electrical current is a complex multiphysics process …

Spin–orbit coupling (SOC) describes the relativistic interaction between the spin and
momentum degrees of freedom of electrons, and is central to the rich phenomena observed …

Materials can harbour quantum many-body systems, most typically in the form of strongly
correlated electrons in solids, that lead to novel and remarkable functions thanks to …

The circular photogalvanic effect (CPGE) is the part of a photocurrent that switches
depending on the sense of circular polarization of the incident light. It has been consistently …

For many materials, a precise knowledge of their dispersion spectra is insufficient to predict
their ordered phases and physical responses. Instead, these materials are classified by the …

Weyl semimetals are topological materials whose electron quasiparticles obey the Weyl
equation. They possess many unusual properties that may lead to new applications. This is …
