Interband optical investigation of Bloch oscillations in semiconductor superlattices TOPICAL REVIEW
... oscillates in time with a characteristic dependence on the static electric field. These oscillations have been observed by several optical methods, both using detection of the interband polarization (four-wave mixing and photorefractive sampling) and intraband polarization (THz emission spectroscopy ...

Quantum Model for the Direct Currents of Becker
... through the cell membrane are Josephson currents. If this is the case, the situation is automatically stationary and dissipation is small as various anomalies suggest. During nerve pulse the situation could of course change and the both dissipating ohmic currents and non-dissipating direct currents ...
