Our experimental research group studies physical properties of low dimensional condensed matter systems. We use advanced nanofabrication techniques combined with controlled sample growth to design and develop sub-micron devices. These devices are used to explore microscopic mechanisms that influence and/or dictate the fundamental physical properties at the sub-micron levels. We explore electron transport in superconducting wires, CDW materials, and correlated oxide nanomaterials under extreme conditions: ultra-low temperatures (10 mK), high magnetic fields (16 T), dimensional confinement and non-equilibrium electric fields. Some of our physics interests include quantum phase transitions (e.g. superconductor-insulator transition), conduction in superconducting wires, phase transition in nanostructures, metal-insulator transitions, and neuromorphic computing applications.
