Yu Chen, PhD defense: “Artificial Synapses based on the Photoconductance of LaAlO3/SrTiO3 QuantumWells”, 14th November
We uncover time-asymmetric photoresponses in oxide quantum wells that can mimic time-correlated plasticity as observed in biological synapses.

Plasticity of Persistent Photoconductance of Amorphous LaAlO3/ SrTiO3 Interfaces under Varying Illumination Conditions
We have studied the magneto-optic responses of magnetoplasmonic couplers in a variety of platforms, including commercial digital disks. Our study reveals pathways to exploit enhanced optical functionality, of potential interest for other nanophotonic devices, such as metasurfaces.

Our group has collaborated in a study published in Nature Physics about a “Giant topological Hall Effect”
The study, led by the group of Manuel Bibes, from Unité Mixte de Physique CNRS/Thales (France), published in Nature Physics on October 15, 2018, describes the discovery of a giant topological Hall effect arising from the topology of spatial distribution of spin textures.
