X Lab

X-ray Laboratory for Research on Quantum Materials


Welcome to the Frano X Lab (a.k.a The X-ray Laboratory for Research on Quantum Materials). Based at the University of California, San Diego near the sunny beaches of La Jolla, CA, our group studies the fascinating properties of materials with strongly correlated electrons. We are interested in investigating long-range periodicities in the spin, charge, and orbital quantum states observed in transition-metal-oxide films, superlattices, heterostructures and single crystals. To explore these spatially periodic behaviors we operate in Fourier space by performing modern x-ray scattering experiments at synchrotrons around the world. Feel free to explore our website for more information.


Two recent results showing in-plane diffraction rings in superconducting cuprates: La2CuO4+y and T'-Nd2CuO4

Alejandro Ruiz joins the group as a UC President's Postdoctoral Fellow

U.S. Department of Energy funds an EFRC to study: Quantum Materials for Energy Efficient Neuromorphic Computing (Q-MEEN-C)

The Process

how is it done?

Imagine It

  • Determine material components of heterostructure
  • Grow it using PLD
  • Characterize the sample here at UCSD using x rays and other in-house facilities

Synchrotron It

  • Apply for beam time
  • Bring sample to the synchrotron
  • Use synchrotron x rays to characterize material and discover new periodicities

Write It

  • Analyze the data
  • Python, Matlab, Mathematica
  • Write and share our discoveries
