The physics of quantum materials is dictated by many-body interactions and mathematical
concepts such as symmetry and topology that have transformed our understanding of matter …

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 …

Topological superconductors are predicted to host exotic Majorana states that obey non-
Abelian statistics and can be used to implement a topological quantum computer. Most of …

The first-principles band theory paradigm has been a key player not only in the process of
discovering new classes of topologically interesting materials, but also for identifying salient …

The concept of synthetic dimensions has generated interest in many branches of science,
ranging from ultracold atomic physics to photonics, as it provides a versatile platform for …

Topological insulators with spin-momentum-locked topological surface states are expected
to exhibit a giant spin-orbit torque in the topological insulator/ferromagnet systems. To date …

Abstract The Kondo insulator SmB6 has long been known to exhibit low-temperature
