Time- and angle-resolved photoelectron spectroscopy experiments are used to monitor the transition between Floquet–Bloch and Volkov states in the topological insulator Bi2Se3. The coherent optical manipulation of solids is emerging as a promising way to engineer novel quantum states of matter1,2,3,4,5. The strong time-periodic potential of intense laser light can be used to generate hybrid photon–electron states. Interaction of light with Bloch states leads to Floquet–Bloch states, which are…

Survival of Floquet–Bloch States in the Presence of Scattering

It is found that Floquet–Bloch states will be destroyed if scattering—activated by electronic excitations—prevents the Bloch electrons from following the driving field coherently, indicating the importance of long scattering times combined with strong driving fields for the successful realization of various Floquet phenomena.

Photoinduced Nonequilibrium Topological States in Strained Black Phosphorus.

Black phosphorus exhibits a photon-dressed Floquet-Dirac semimetal state, which can be continuously tuned by changing the direction, intensity, and frequency of the incident laser, and topological surface states exhibit nonequilibrium electron transport in a direction locked by the helicity of CPL.

Using time- and angle-resolved photoemission spectroscopy, it is shown that an intense ultrashort midinfrared pulse with energy below the bulk band gap hybridizes with the surface Dirac fermions of a topological insulator to form Floquet-Bloch bands.

Ultrafast surface carrier dynamics in the topological insulator Bi₂Te₃.
