An efficient source of terahertz radiation has the potential to improve characterization methods for drugs, proteins and bacteria, enable ultra-fast wireless data transfer over short distances for use in “smart factories”, and offer enhanced detection capabilities with the ability to see through packaging. However, terahertz light is particularly difficult to produce, and existing sources remain too bulky and power-hungry for widespread application.
We are working to develop more compact and efficient terahertz light sources using polaritons – hybrid particles consisting of a photon coupled strongly with a material excitation. This approach utilizes a plethora of quantum phenomena, from trapped photons, to quasiparticles, to Bose-Einstein condensation. By exploiting these unconventional effects we hope to pave the way towards a long-awaited practical source of terahertz light.
Combined momentum- and real-space photoelectric probes of dimensionality-tuned Weyl semimetals
Summary The library of two-dimensional (2D) materials has recently grown to include topological insulators and semimetals. Their incorporation in special device geometries may lead to novel quantum electronics with enhanced functionalities. Weyl semimetals, in particular, offer the most robust form of topological protection. Recent results from our group indicate that Weyl nodes should be […]

Mesoscopic systems as coherent control elements
Summary Mesoscopic systems provide a new tool for quantum systems design. In particular, they are enabling of robust quantum control. Here “mesoscopic system” refers to a connected network where each element, if studied alone, would be a quantum bit. The network is too big to be treated fully quantum mechanically. We do not have individual […]

Repurposing potential drug candidates for the treatment of COVID-19
Summary The main protease (Mpro) in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for the coronavirus disease (COVID-19), has emerged as a promising drug target. The scientific community has produced a large number of crystallographic structures of the protease, which mediates viral replication and transcription. These structures report several fragments with varied chemotypes […]

Materials for Majorana-based Topological Qubits
Summary Topological qubits offer a novel pathway to scalable quantum computing by simultaneously allowing for ease of coupling between qubits and strong decoupling of qubits from noise and dissipation. The most promising direction explores the topologically induced protection of theoretically predicted exotic quasiparticles, the so-called Majorana Zero Modes or MZMs. To-date MZMs, which follow […]
