R. Hussein and S. Kohler. arXiv:1503.00534 Annalen der Physik, March 3, 2015 We investigate electron transport in two quantum circuits with mutual Coulomb interaction. The first circuit is a double quantum dot connected to two electron reservoirs, while the second one is a quantum point contact in the weak tunneling…
T. Stauber, T. Low and G. Gómez-Santos Phys. Rev. Lett. 120, 046801 (2018) We present an effective (minimal) theory for chiral two-dimensional materials. These materials possess an electromagnetic coupling without exhibiting a topological gap. As an example, we study the response of doped twisted bilayers, unveiling unusual phenomena in the…
G. Engelhardt, M. Benito, G. Platero, G. Schaller and T. Brandes. Phys. Rev. B 96, 241404(R) (2017) The appearance of topological effects in systems exhibiting a nontrivial topological band structure strongly relies on the coherent wave nature of the equations of motion. Here, we reveal topological dynamics in a classical stochastic…
