The condition of equilibrium puts constraints on what types of matter can exist, and on their quantitative characteristics.  It has been proposed that strong electromagnetic drive can induce new phases not available as ground states, or quantitatively favor one or more competing ground states under a set of similar equilibrium conditions (temperature, magnetic field, etc.).  Accessing such phases with electrical measurements, however, is limited by the short timescales during which electromagnetic drive can be applied, itself limited both by the availability of pulsed laser sources and limits on power dissipation within the sample itself.   We are developing a THz-on-a-chip technique to measure transport on picosecond timescales, allowing us to probe the nonequilibrium properties of strongly correlated and two dimensional materials. Photons for this project are provided by our collaborators, Rick Averitt (UCSD) and David Hsieh (Caltech).
