DESCRIPTION:In one-dimensional conductors\, electron-electron interactions
  result in correlated electronic systems markedly different from conventio
 nal Fermi liquids. At low energy\, a hallmark signature of these so-called
  Tomonaga-Luttinger liquids (TLL) is the universal conductance scaling cur
 ve in presence of an impurity. A seemingly different problem is that of th
 e quantum laws of electricity\, when distinct quantum conductors are assem
 bled in a circuit. In particular\, the conductance across a quantum conduc
 tor embedded in a dissipative circuit is suppressed at low energy\, a phen
 omenon called dynamical Coulomb blockade (DCB).\n\nIn this talk\, I will p
 resent an experimental investigation of the DCB on a single-channel quantu
 m conductor realized by a quantum point contact in a two-dimensional elect
 ron gas. A remarkable feature of the data is that it points to a general p
 henomenological expression for the conductance\, for whatever single-chann
 el quantum conductor that is embedded in an arbitrary linear circuit. In t
 he particular case of a pure resistance in series with the single-channel 
 conductor\, theory predicts a mapping between DCB and the transport across
  a TLL with an impurity. By confronting the phenomenological expression an
 d the data with the TLL universal conductance scaling curve\, we demonstra
 te experimentally this mapping.\n\nThe powerful TLL framework advances our
  understanding of the laws governing quantum transport with distinct quant
 um components. Reciprocally\, the demonstrated mapping provides a new test
 -bed for TLL predictions.\n\nA. Anthore\, S. Jezouin\, F.D. Parmentier\, M
