The exciton, a bound state of an electron and a hole, is a fundamental quasiparticle induced
by coherent light–matter interactions in semiconductors. When the electrons and holes are …

Spin–orbit interaction gives rise to a splitting of surface states via the Rashba effect, and in
topological insulators it leads to the existence of topological surface states. The resulting …

Ultrafast charge and spin dynamics have immense effects on the applications of topological
insulators (TIs). By performing spin-adiabatic nonadiabatic molecular dynamics simulations …

By means of angle-resolved photoemission spectroscopy (ARPES) measurements, we
unveil the electronic band structure of three-dimensional PbBi6Te10 topological insulator …

The use of topological edge states for spintronic applications could be severely hampered
by limited lifetimes due to intrinsic many-body interactions, in particular electron-phonon …

Anisotropic bulk Dirac (or Weyl) cones in three-dimensional systems have recently gained
intense research interest as they are examples of materials with tilted Dirac (or Weyl) cones …

We report on the electronic structure of the elemental topological semimetal α− Sn on InSb
(001). High-resolution angle-resolved photoemission data allow us to observe the …

The topological crystalline insulator tin telluride is known to host superconductivity when
doped with indium (Sn 1− x In x Te), and for low indium content (x= 0.04) it is known that the …

We have investigated the optical properties of thin films of topological insulators Bi 2 Te 3, Bi
2 Se 3, and their alloys Bi 2 (Te 1− x Se x) 3 on BaF 2 substrates by a combination of …

Rashba states have been actively revisited as a platform for advanced applications such as
spintronics and topological quantum computation. Yet, access to the Rashba state is …
