We are studying collective quantum phenomena in solids using novel optical techniques.
Traditionally material properties are controlled by changing the material composition or by the thermodynamic parameters of their environment such as magnetic fields, temperature pressure etc. By tailoring ultrafast intense laser pulses we can drive materials out of equilibrium and control material properties using light. 
Many quantum phenomena in solids are hidden even from the best microscopes. To detect these otherwise hidden orders in our lab we look at the symmetry properties manifested by the underlying quantum nature of our physical system. 
All material properties, from superconductivity and magnetism to mechanical properties are governed by the chemical composition and atomic positions. Observing structural dynamics on ultrafast timescales provide an exciting glimpse into the interplay between the atoms and the novel phases hosted by quantum materials. 
While photons don’t interact in free space interactions between them can be mediated by matter leading to nonlinear optical effects. We utilize nonlinear optics to learn about quantum material properties. 
We use our spectroscopic analytical tools in collaborations with the TAU archeology department. In this photo the pigments of an Egyptian stamp are studied using Raman spectroscopy.
