Active Research

We are working on quantum phenomena in low-dimensional systems, especially at the intersection of superconducting and topological states. Our core work focusses on nano-fabrication and transport measurements of novel quantum devices. We also measure electrical current fluctuations due to quantum effects at millikelvin (mK) temperatures. Finally, we can characterize the circuit elements used in superconducting qubits with our high-frequency setup.

Superconducting effects in the quantum Hall regime

We induce superconducting correlations in the topologically protected edge states in quantum Hall systems. This research is inspired by the search for the topologically protected states for quantum computation.

Multi-terminal Josephson junctions

Via both experiment and simulation, we explore complex phase space in graphene-based multi-terminal Josephson junctions and Josephson circuits. These devices demonstrate potential to host synthetic topological states of matter.

Superconductivity at the complex oxide Interfaces

We aim to elucidate the nature of superconductivity in these systems. Displaying properties such as anisotropic electronic transport and high kinetic inductance in the superconducting state, they provide a rich test bed for fundamental physics and technological advancement.

Qubits and high frequency measurements

We characterize and design qubits in novel systems and explore Josephson junction dynamics. By driving Josephson circuits with high-frequency radiation, we have revealed unintuitive temperature dependence.
