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 …

Angle resolved photoemission spectroscopy (ARPES) is commonly known as a powerful
probe of the one-electron removal spectral function in ordered solid state. With increasing …

In solids, electronic Bloch states are formed by atomic orbitals. While it is natural to expect
that orbital composition and information about Bloch states can be manipulated and …

The interplay between chirality and topology nurtures many exotic electronic properties. For
instance, topological chiral semimetals display multifold chiral fermions that manifest …

Light beams with a helical phase-front possess orbital angular momentum along their
direction of propagation in addition to the spin angular momentum that describes their …

The dispersion of charge carriers in a metal is distinctly different from that of free electrons
owing to their interactions with the crystal lattice. These interactions may lead to …

Spin transfer torques allow the electrical manipulation of magnetization at room temperature,
which is desirable in spintronic devices such as spin transfer torque memories. When …

We report the detailed electronic structure of WTe 2 by high resolution angle-resolved
photoemission spectroscopy. We resolved a rather complicated Fermi surface of WTe 2 …

SmB6, a well-known Kondo insulator, exhibits a transport anomaly at low temperature. This
anomaly is usually attributed to states within the hybridization gap. Recent theoretical work …

Recent experimental observation of an unexpectedly large current-induced spin-orbit torque
in surface oxidized Cu on top of a ferromagnet pointed to a possibly prominent role of the …
