A central theme in quantum materials research is the emergence of new macroscopic properties from the collective interaction between microscopic degrees of freedom. Understanding the exact nature and driving mechanism of these emergent physics is often a formidable challenge, yet is critical to engineer desired quantum matter properties and to harness them for functional applications.

Our research group is specialized in tackling this problem by utilizing multiple advanced scattering and spectroscopic techniques, that provide complementary and multifaceted information on quantum materials. These include:

• Angle-resolved photoemission spectroscopy resolving fermionic information in solid (electronic structure),

• Resonant elastic/inelastic X-ray scattering providing bosonic information (orders and excitations),

• Time-resolved scattering & spectroscopy detecting out-of-equilibrium dynamics, and

• Spatially-resolved nanospectroscopy measuring domains, defects, and devices.

Our research is problem-driven: depending on the quantum material of interest, we find best toolsets to illuminate its underlying physics.

We actively use synchrotrons and X-ray free electron laser facilities worldwide, including ALS (USA), CLS (Canada), DLS (UK), BESSY (UK), NSLS-II (USA), MAX-IV (Sweden), LCLS (USA), and PAL-XFEL (South Korea).
