Spectrally resolved wave-mixing between near- and far-infrared pulses in gas [PDF]

, 2013
We investigate the nonlinear wave-mixing in gases between intense, short optical pulses and long-wavelength fields (mid infrared and terahertz). We show numerically that the beating between the sum- and difference-frequency generation components can be ...

Photon-Assisted Shot Noise in Graphene in the Terahertz Range [PDF]

Physical Review Letters, 2016
When subjected to electromagnetic radiation, the fluctuation of the electronic current across a quantum conductor increases. This additional noise, called photon-assisted shot noise, arises from the generation and subsequent partition of electron-hole pairs in the conductor.

Thermal Radiation from Carbon Nanotubes in the Terahertz Range [PDF]

Physical Review Letters, 2007
The thermal radiation from an isolated finite-length carbon nanotube (CNT) is theoretically investigated both in near- and far-field zones. The formation of the discrete spectrum in metallic CNTs in the terahertz range is demonstrated due to the reflection of strongly slowed-down surface-plasmon modes from CNT ends.
