Burak Guzelturk

In my research, I am interested in understanding and controlling the coupling between lattice and electron dynamics in quantum, photonic and electronic materials. This requires the use of various time-resolved optical and structural techniques to measure dynamics across sub-nanosecond timescales. At the Advanced Photon Source, I develop new time-resolved X-ray diffraction and microscopy tools. Our existing capabilities include:

Pump - probe X-ray diffraction (total scattering and WAXS)
Time-resolved X-ray nanodiffraction microscopy
X-ray induced optical luminescence (time-resolved RL, light yield, spatial resolution)

ACTIVE PROJECTS

Light-driven phase & symmetry transformations

Field/light-driven manipulation of ferroics

Polaronic lattice deformations

X-ray scintillators
