Description | explored initial avenues of research and discussed relevant models. Established a collaborative structure with Loughborough. Explored some preliminary lattice spin systems. Investigated entanglement and negativity behavious at finite temperature in spin chains (in collaboration with project partner Prof Pollmann), and in 2D toy models (toric code). Development of mean field approaches for spin liquids; investigation of dynamics of quasiparticles in quantum spin liquids. Explored dimer models for high temperature superconductivity and found good agreement with experimental results. We proposed a mechanism for driven superconductivity. We further developed an understanding of dephasing in spin chains and we are working on transferring it to higher dimensional systems. We explored dynamics in pyrochlore oxides at the microscopic level and started exploring the collective behavour. We proposed a novel numerical approach to study quantum spin liquids, and in particular their excitations, at finite temperature. We characterised the dynamics and correlations in quantum spin liquids at finite temperature, where one type of excitation acts as disorder for the other, through their mutual anyonic statistics. |
