The artificial neural network revolution has sparked interest in one of the most intriguing phenomena of condensed matter physics: the metal-insulator transition in strongly correlated materials. This fascinating family of materials exhibits a plethora of phases and competing phenomena which can give rise to intrinsic bio-mimetic functionalities such as those of neurons and synapses. Our group tackles the challenges of understanding the most fundamental properties of these materials and harnesses them for developing energy efficient and scalable neuromorphic devices and networks.

• Interplay between structural, magnetic and electronic degrees of freedom in strongly correlated materials
• Resistive switching in transition metal oxides – electrical triggering of insulator-to-metal transitions and oxygen migration
• Roles of defects in Mott insulators – linking microscopic electronic properties to collective phenomena
• Dynamic properties of Mott insulators driven out of equilibrium
• Energy efficient neuromorphic computation based on Mott insulator hardware: solid state neurons and synapses and their coupling

These topics are explored using a combination of state of the art fabrication and characterization techniques including: sputtering, x-ray diffractometry, transport, lithography, muon spin rotation, quantum sensing using NV-centers and cryogenic optical and scanning probe microscopy.

We are recruiting graduate students for M.Sc., M.A.Sc., Ph.D and postdoctoral positions for our research projects. Please email (ykalchheim@physics.ucsd.edu) for details. Undergraduates who are interested in short term projects are also welcome to apply.Preference will be given to applicants with background in one or more of the following disciplines: Materials Science, Physics, Chemistry and Electrical Engineering.
We look forward to hearing from you!
