Julia S. Meyer, from The Ohio State University, will visit the University of Arizona as a UA ADVANCE Junior Scientist Speaker and will give a 50- to 60-minute lecture on her research as part of the physics department lecture series. Philippe R. Jacquod, associate professor of physics, nominated her for the award.

With the need to miniaturize electronic components below the nanoscale barrier, low-dimensional physics has come to play a central role in modern condensed matter physics and nanoscience. Meyer's research investigates the interplay between low dimensionality as well as interactions and disorder in nanoelectronic systems. These aspects are key to understanding how electricity is transmitted across such systems, a necessary step if one wants to include them as building blocks in nanoscale electronic circuits. Some of Meyer's more spectacular theoretical results include the construction of the phase diagram for interacting electrons in quantum wires, with the emergence of paramagnetic and (finite-sized) ferromagnetic phases, and the breakdown of Luttinger physics with the emergence of a single, fermionic gapless mode.

Meyer's lecture is titled "Quasi-one-dimensional Electron System."
