Quantum transport and time-dependent dynamics of Dirac fermions (A07)

• Subject Area: Theoretical Condensed Matter Physics
• Term: since 2017
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 314695032

The project is centred around various inter-related quantum phenomena of Dirac fermions on TI surfaces: Three complementary research streams encompass (i) ultrafast dynamics subject to laser pulses, together with phenomena such as high-harmonic generation and dynamical anomalous Hall effects; (ii) various magneto-transport phenomena in TI-based nanowires and tubes, in particular peculiar geometrical quantum effects arising at curved surfaces; (iii) effects of spin-momentum locking on the morphology of confined topological surface states in “TI quantum corrals”. Semiclassical path integral methods, quantum mechanical wave-packet techniques and transport codes will be used.
