48: Josh Caldwell - Bend light the wrong way

Josh Caldwell from Vanderbilt University, and formerly the United States Naval Research Laboratory, talks about his pioneering work in infrared polaritonics. Polaritons are quasiparticles that couple photons to the motion of electrons or atoms in a material, and allow you to squeeze and manipulate light in nanoscale volumes. In the infrared, this capability may one day allow, for example, the roof of your home to cool even when in direct sunlight. Josh and Mike get a little 'in the weeds,' but that's what podcasts are for! Be sure not to miss the great career advice Josh sprinkles in along the way. (Recorded on January 24, 2019.
