We study the spontaneous breaking of rotational symmetry in the helical surface state of three-dimensional topological insulators due to strong electron-electron interactions, focusing on time-reversal invariant nematic order. Owing to the strongly spin-orbit coupled nature of the surface state, the nematic order parameter is linear in the electron momentum and necessarily involves the...
Time-reversal symmetry (TRS) and topological phenomena associated with it are hot topics in condensed matter physics. The existence of the gapless Andreev bound states on [110] surfaces of a high-Tc cuprate superconductor is guaranteed by the bulk-edge correspondence to a topological invariant protected by TRS. Recent experiment on a nanoscale cuprate island
has detected a full gap that is...
The Institut Quantique (IQ) at the Université de Sherbrooke is an open and collaborative research environment with expertise ranging from fundamental to applied at the interface of quantum information, quantum materials and quantum engineering. In this talk, an overview of the main research directions at IQ will be presented.
