G. Lawrence (Larry) Carr

Physicist


Larry Carr is the Group Leader for Low Energy Spectroscopy and manages infrared beamlines U4IR & U12IR that primarily serve the condensed matter physics community. He also works on infrared beamline instrumentation and technique development for both the existing NSLS and future NSLS-II facilities. His current research interests include non-equilibrium dynamics in superconductors and semiconductors studied by time-resolved spectroscopy & magnetospectroscopy, plus the development and application of intense coherent THz pulse sources.
