Two photon excitation of chr2
Webproportional to the exciton–photon coupling constant; i.e., it does not depend on the amplitude of the electro-magnetic wave field. The phenomenon of nutation in a system of coherent excitons, photons, and biexcitons in the range of the M luminescence band of semiconductors was investigated in [7–10]. The two-photon nutation in a system of WebA second cation channel, Volvox-Channelrhodopsin-1 (VChR1) is a red-shifted ChR variant isolated from spheroidal alga Volvox carteri [14].Owing to differences in the RSB binding …
