I am particularly interested in the basic physics and possible device applications of novel states of matter, such as 2D topological insulators, topological superconductors and their excitations (Majorana zero-modes), and emergent electronic properties in complex oxide interfaces.

Our interest lies in the design, nanofabrication and experimental study of nanoscale devices based on novel low-dimensional materials, such as quantum spin Hall insulators (2D topological insulators), complex oxide interfaces and semiconductor nanowires. Our current research explores three main directions: topological superconductivity in hybrid semiconductor-superconductor systems, magnetism and superconductivity in oxide interfaces, and spin manipulation in low-dimensional structures (quantum dots, spin-helical liquids and 2D topological insulators).

Topological superconductivity is a fascinating condensed matter phase that is predicted to host Majorana zero-modes. When attached to a local defect such as a domain wall, Majorana modes, unlike conventional fermions, are expected to show non-Abelian exchange statistics. Because of their exotic properties and their topological robustness, Majoranas have become very important in the nascent field of topological quantum computing, which aims to exploit topological protection for decoherence-free quantum information processing.

Low-dimensional semiconductors with strong spin-orbit coupling open up avenues for exploring novel spin physics. For example, the spin orientation can be coupled to the electron propagation direction by applying a magnetic field along the nanowire. We are interested in the intriguing possibility of using such spin-helical modes as spin filters or to couple single spins from separate quantum dots.
