Title: Measuring atomic-scale wavefunctions and dynamics inside the hidden order compound URu2Si2 with X-ray spectroscopies

Speaker: Prof. L. Andrew Wray
     (Department of Physics, New York University, USA)

Place:Science Building III 4F SC427

Abstract:
Understanding the emergent wavefunctions of correlated electron systems
requires experimental probes that can resolve electronic states on an atomic scale.
However, imaging techniques such as STM that resolve single atoms do not provide
a good way to distinguish the entangled symmetries of nearby electrons.
I will talk about how energy-resolved scattering measurements performed
with resonance-tuned X-rays can open a unique window into many-body entangled states
on an atomic length scale and femtosecond time scale. The presentation will focus on data
that unveil entangled wavefunction symmetries and energetics of uranium electrons
in the "hidden order" compound URu2Si2, as well as touching on other material systems
of current interest.
