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 that 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.

Specific research directions:

  • Energy-efficient neuromorphic computation based on Mott insulator hardware: solid-state neurons and synapses and their coupling
  • The 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

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 (ykalcheim@technion.ac.il) for details.
Undergraduates who are interested in short-term projects are also welcome to apply.
Preference will be given to applicants with a background in one or more of the following disciplines: Materials Science, Physics, Chemistry, and Electrical Engineering.

We look forward to hearing from you!
