Query: Photon-assisted Dynamical Coulomb Blockade in a Tunnel Junction   We report measurements of photon-assisted transport and noise in a tunnel
junction in the regime of dynamical Coulomb blockade. We have measured both dc
non-linear transport and low frequency noise in the presence of an ac
excitation at frequencies up to 33 GHz. In both experiments we observe replicas
at finite voltage of the zero bias features, a phenomenon characteristic of
photon emission/absorption. However, the ac voltage necessary to explain our
data is notably different for transport and noise, indicating that usual theory
of photon-assisted phenomena fails to account for our observations.
