Research

Physics of complex electron systems. Strongly correlated transition metal oxides (colossal magnetoresitive manganites, cuprate high temperature superconductors, cobalt oxides), Fe-based high temperature superconductors, binary oxides (VOx, V2O3, EuO, CrO).

Physics of novel materials and novel materials characterization methodology. Materials for energy storage (cobaltates, delafossites, co-doped TiO2) and technological applications such as sensors, electronics, displays (transparent conducting oxides).

Properties, growth and characterization of low dimensional materials, nanostructures, surfaces and interfaces in materials of technological relevance.

Light - matter interaction and physics of the fundamental processes concerning the use and development of soft-x-ray spectroscopies techniques. High-resolution angle-resolved photoemission spectroscopy (ARPES), core level photoemission spectroscopy, x-ray absorption spectroscopy (XAS), soft x-ray emission spectroscopy (XES) and inelastic x-ray scattering (RIXS). Development of advanced scientific instrumentation for x-ray spectroscopies.

Atomic, electronic, magnetic and orbital dynamics in complex electron systems. Sub-picoseconds temporal dynamics of different degrees of freedom in complex electron systems. Phase transitions.


Teaching

Dr. Mannella has taught the following courses:


Brief Vita

I obtained my Ph.D. in Physics in September 2003 from UC Davis (CA) with Prof. C. S. Fadley. Immediately after, I became a Postdoctoral Fellow at Stanford University (CA) with Prof. Z. X. Shen, with a joint appointment as a Visiting Scientist at the Advance Light Source (ALS) in Berkeley (CA) in the User Support System Group of Dr. Z. Hussain. In October 2006, I obtained a joint position as Research Associate at Stanford University in Prof. Z. X. Shen's group and Beamline Scientist at the ALS in the User Support System Group of Dr. Z. Hussain. I became an Assistant Professor in the Physics Department at UTK in August 2007. For a full CV, including full publications record, go here.


For Prospective Students and Post-Doctoral Fellows

Our group is composed of two postdoctoral researchers (Dr. Cheney and Dr. Vilmercati) as well as students. A couple of positions are immediately available for highly motivated graduate students who are interested in the study of novel materials and complex electron systems with soft x-ray spectroscopies. If interested, please e-mail (nmannell@utk.edu) or call me in the office (4-6123). A description of our research activities and ongoing projects may be found here.
