The ultrafast terahertz (THz) spectroscopy group is a new research division at uOttawa. Our aim is to improve the general understanding of quantum interactions in solid state. To do so we rely on time-resolved THz technologies to map out the ultrafast dynamics of a vast range of microscopic interactions in materials. In some extreme cases, these interactions lead to macroscopic quantum phenomena such as superconductivity or dynamical Bose-Einstein condensation. In addition to exploring these fascinating phase transitions, we also develop optical tools to control them.
