Biography

Professor Abbamonte received his Ph.D from the University of Illinois at Urbana-Champaign in 1999, having done his research with the then thriving Materials Physics Department at Bell Laboratories. He then went to the University of Groningen in The Netherlands on an IRFAP fellowship from the National Science Foundation. In 2001, he returned to the U.S. as a postdoc in biophysics at Cornell University, where he studied photosynthesis in Rhodobacter sphaeroides, and joined the scientific staff at Brookhaven National Laboratory in 2003. He was recruited to the Department of Physics in August of 2005.

Professor Abbamonte is one of the originators of the technique of resonant soft x-ray scattering, which he has used, among other things, to discover a Wigner crystal in doped spin ladders, and to show that stripes in copper-oxide superconductors are charged. This technique is now in use at every major synchrotron facility in the world. He is also known for his solution to the phase problem for inelastic x-ray scattering, permitting real-time imaging of electron motion in condensed matter with attosecond time resolution. He has recently used this approach, for example, to image the formation of excitons in insulators, and to measure the effective fine structure constant of graphene.

Abbamonte is the founder of Inprentus, a premium optics manufacturer based at the University of Illinois Research Park.

One of the greatest mysteries in condensed matter physics is the exact relationship between charge order and superconductivity in cuprate superconductors. In superconductors, electrons move freely through the material—there is zero resistance when it’s cooled below its critical temperature. However, the cuprates simultaneously exhibit superconductivity and charge order in patterns of alternating stripes. This is paradoxical in that charge order describes areas of confined electrons. How can superconductivity and charge order coexist?  

Now researchers at the University of Illinois at Urbana-Champaign, collaborating with scientists at the SLAC National Accelerator Laboratory, have shed new light on how these disparate states can exist adjacent to one another. Illinois Physics post-doctoral researcher Matteo Mitrano, Professor Peter Abbamonte, and their team applied a new x-ray scattering technique, time-resolved resonant soft x-ray scattering, taking advantage of the state-of-the-art equipment at SLAC. This method enabled the scientists to probe the striped charge order phase with an unprecedented energy resolution. This is the first time this has been done at an energy scale relevant to superconductivity.

Since the discovery two decades ago of the unconventional topological superconductor Sr2RuO4, scientists have extensively investigated its properties at temperatures below its 1 K critical temperature (Tc), at which a phase transition from a metal to a superconducting state occurs. Now experiments done at the University of Illinois at Urbana-Champaign in the Madhavan and Abbamonte laboratories, in collaboration with researchers at six institutions in the U.S., Canada, United Kingdom, and Japan, have shed new light on the electronic properties of this material at temperatures 4 K above Tc. The team’s findings may elucidate yet-unresolved questions about Sr2RuO4’s emergent properties in the superconducting state.
