We're answering
complex questions.
Research in the Benedek group is focused on using a combination of crystal chemistry, symmetry principles and Density Functional Theory calculations to connect material properties to bonding and physical mechanisms, with a particular emphasis on controlling the structures and properties of complex oxides out of equilibrium. Our goal is to use advances in the fundamental understanding of mechanisms to create design rules for new materials with enhanced or targeted properties. We are pursuing these ideas through three main research thrusts, described further in Research.

Ultrafast Control of Material Optical Properties via the Infrared Resonant Raman Effect
- Authors:
- G. Khalsa, N. A. Benedek and J. Moses, Physical Review X, 11 021067

- Synopsis:
- We show that resonant optical excitation of IR and Raman phonons gives rise to a Raman-scattering effect that can induce giant shifts to the refractive index and induce new optical constants that are forbidden in the equilibrium crystal structure.
