• ]. For the lower-frequency range, a new class of single-microwave-photon detectors is needed. With regard to this, a current-biased Josephson junction (JJ) is of particular interest for applications as a threshold detector since its phase dynamics is altered even by a weak probe field. Rich dynamics of

• (thickness) by approx. 100 nm (length of GNB, or along the GNR). This detailed prediction is open to experimental verification. An impact is expected onto further studies of interplay between atomic vibrations and electromagnetic waves in nanoobjects. Keywords: longitudinal acoustic phonon; microwave photon

• onto the vacant level corresponding to the energy of this phonon, measured from EF. On relaxation, the energy of the emitted THz photon would roughly match (neglecting a much smaller energy of the microwave photon) that of the LAVM. Consequently, the “primary” emitted THz spectrum (intensity

• Fermi electron with momentum pF can be encountered, prone to absorb a microwave photon. The contribution of the latter pph to the electron momentum will be neglected here due to its relative smallness (as was done above for the energy hν). Assuming the vector s to be the sum of pF and nvmq, the
