Research Interests

Quantum transport including graphene.— Nanostructures with normal, superconducting or ferromagnetic components possess a wide range of properties governed by quantum mechanics. Quantum transport is the field which explores and exploits these properties via conductance phenomena. In recent years, this field has received an enormous boost through the realization of graphene and related materials, including topological insulators. My research in this area focusses on the role of multiple scattering by disorder and interfaces. For graphene, I have made seminal contributions on chemical disorder, coupling to metallic contacts and quantum pumping (transport induced via parametric variations). Ongoing work addresses the effects of strain, the role of disorder in the quantum Hall effect of bilayer graphene, quantum pumping in topological insulators, and the question whether a recent groundbreaking experiment indeed provides unambiguous signatures of Majorana fermions. This research combines methods from scattering theory, random-matrix theory, semiclassics and phenomenology with exact numerics (e.g., based on the recursive Green function technique). Earlier work concerned the superconducting proximity effect, Anderson localization, and shot noise.

Quantum optics, microlasers and photonics.—Small-scale optical systems display intricate quantum effects which when controlled precisely open up applications in quantum information and precision sensing. In larger scale photonic systems, classical wave propagation can be manipulated to produce phenomena such as negative refraction, while microcavities and photonic crystals allow the tailoring of modes and dispersions for a wide range of practical applications. My research focusses on the interplay of amplification and absorption with multiple scattering, mostly applied to microcavity lasers where this interplay determines the mode formation, mode selection and quantum noise. The activities started with research on dynamics in disordered waveguides and then expanded into the quantum-optical treatment of mesoscopic and nonclassical light emitters and dielectric microlasers, as well as the semiclassical characterization of the modes in such systems. Current activities focus on photonic hybrid arrangements, especially those that combine amplification and absorption. I currently also explore the concept of topologically protected states (Landau levels and midgap states) in the photonic setting. Activities on polariton physics in collaboration with experimentalists in Sheffield aim at the electronics/optics interface in a setting where complex nonequilibrium electronic dynamics become important. Part of this work is integrated into the DFG Forschergruppe 760 (Scattering Systems with Complex Dynamics), where I am an external fellow.

Quantum dynamical systems, including atomic systems.— Quantum dynamics illuminates quantum effects in the time domain. This is particularly relevant for driven systems, but also can provide a useful perspective on stationary states. In this community, I am well known for my work on the fractalWeyl law (characterizing resonances in complex open systems), and in particular for the development of semiclassical approaches that apply to generic dynamics. Recently I have forged an EPSRC-funded alliance with atomic physicists at UCL and quantum chemists at Leeds, where we aim to merge these methods with other orbit-based methods linked to time-dependent DFT and the coupledcoherent-state method (CCS). My other research in this area informs the investigation of microcavity lasers and quantum transport mentioned above.
