Description

Condensed Matter Physics

Quantum many-body physics in strongly-correlated electron and other novel quantum systems. Examples include high-temperature superconductors, Fe-pnictide superconductors, toplogical quantum matter, low dimensional metal and density wave materials. The main tool is high resolution angle-resolved photo-emission spectroscopy, but other photon based tools are also used, such as resonance x-ray scattering and inelastic x-ray scattering.

Lasers and Accelerators

Development of laser capabilities to enable condensed matter physics experiments---examples include time resolved photo-emission spectroscopy using UV lasers and soft x-ray scattering using the LCLS.

Nanoscience and Quantum Engineering

Devepment of AFM-based near field microwave microscopy that enables measurement of electrical properties with 50nm or better resolution---this is becoming a powerful tool to study physics and material science problems of mesoscopic length scale., such as metal-insulator transition with mesoscale inhomogeneity, quantum hall edge physics. Investigation of the physics and applications of diamondoids and related materials, where the combination of diamond structure and nm length scale gives rise to unique properties. Use of nanostructured material and devices to realize the goal of photon enhanced thermionic emission for concentrator solar conversion.
