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.


We have measured the magnetic excitation spectrum of Quantum Spin Liquid candidate material using unprecedented resoultion and an applied magnetic field using x-rays (not neutrons!)

Our latest paper in Nature Communications adds important insight into the origin of charge ordering in the copper-oxide plane of high-Tc supercondcutors, highlighting the role of the Coulomb interaction. This is collaboration with Eduardo da Silva Neto and Fabio Boschini.

As part of the Q-MEEN-C collaboration, we have created neural trees in hardware using nickelates, and imaged them using nano-focused x rays.

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
