We report femtosecond time-resolved reflectivity measurements of coherent phonons in tellurium
performed over a wide range of temperatures (3K to 296K) and pump laser intensities. A totally
symmetri...

We review recent theoretical calculations of charge transfer through mesoscopic devices in response to slowly-oscillating, spatially-confined, potentials. The discussion is restricted to non-interacti...
