Physics Colloquium 

Apparent zero field breakdown of the Fermi liquid in an oxide two-dimensional electron system 


Joseph Falson 

Assistant Professor 

Department of Applied Physics and Materials Science 

California Institute of Technology 



I will discuss recent experimental work on the low-temperature transport in a strongly interacting zinc oxide-based high mobility two dimensional electron system. The data shows signatures of the transition between a Fermi liquid phase and a Wigner crystal phase at zero magnetic field. Other features of the data suggest new mysteries in the vicinity of this transition. I will discuss the data in detail, all recorded at low temperatures, and highlight some mysteries that emerge as the temperature and spin polarization are tuned. 





Joseph Falson's research focuses on the synthesis and characterization of quantum materials that display emergent functionalities. The group specializes in the thin-film growth of high quality crystals and their physical evaluation in extreme environments, including at low temperature and high magnetic field.
