Weak Localisation in Clean and Highly Disordered Graphene

Michael Hilke, Mathieu Massicotte, Eric Whiteway +1

We look at the magnetic field induced weak localisation peak of graphene samples with different mobilities. At very low temperatures, low mobility samples exhibit a very broad peak…

Weak Localization in Graphene: Theory, Simulations and Experiments

M. Hilke, M. Massicotte, E. Whiteway +1

We provide a comprehensive picture of magnetotransport in graphene monolayers in the limit of non-quantizing magnetic fields. We discuss the effects of two carrier transport, weak…

Robustness of the helical edge states in topological insulators

Xue-Feng Wang, Yibin Hu, Hong Guo

Topological insulators (TI) are materials having an energy band gap in the bulk and conducting helical electronic states on the surface. The helical states are protected by time re…

Spin-echo dynamics of a heavy hole in a quantum dot

Xiaoya Judy Wang, Stefano Chesi, William A. Coish

We develop a theory for the spin-echo dynamics of a heavy hole in a quantum dot, accounting for both hyperfine- and electric-field-induced fluctuations. We show that a moderate app…

Anomalous magnetotransport through reflection-symmetric artificial molecules

B. D'Anjou, W. A. Coish

We calculate magnetotransport oscillations in current through a triple-quantum-dot molecule, accounting for higher harmonics (having flux period h/ne, with n an integer). For a ref…

Electron-phonon mediated heat flow in disordered graphene

Wei Chen, Aashish A. Clerk

We calculate the heat flux and electron-phonon thermal conductance in a disordered graphene sheet, going beyond a Fermi's Golden rule approach to fully account for the modification…
