Research interest
– quantum magnetism, primarily focused on low-dimensional and frustrated antiferromagnets. That includes low-energy excitations in Shastry-Sutherland model, frustrated quasi-1D antiferromagnets, quantum spin liquids.
– metal-to-insulator transitions. In particular, the role of electron correlations on superconductivity and magnetic properties of doped fullerides. Also, unconventional superconductivity in iron-based superconductors, quasi-1D superconductors where centre of symmetry is removed.
– quantum sensing and quantum technologies based on molecular qubits
– broad specialisation in magnetic resonance measurements, including nuclear magnetic resonance, electron paramagnetic resonance and muon spin relaxation.
– Development of novel experimental methods, e.g., development of high-pressure probes for magnetic resonance, nitrogen vacancy magnetometry for surface spin detection.
