In one-dimensional conductors, interactions result in correlated electronic systems. At low energy, a hallmark signature of the so-called Tomonaga-Luttinger liquids is the universal conductance curve predicted in presence of an impurity. A seemingly different topic is the quantum laws of electricity, when distinct quantum conductors are assembled in a… (More)

It is shown that a one-channel coherent conductor in an Ohmic environment can be mapped to the impurity problem in a Tomonaga-Luttinger liquid. This allows one to determine nonperturbatively the effect of the environment on I-V curves, and to find an exact relationship between dynamic Coulomb blockade and shot noise. We investigate critically how this… (More)

We derive fluctuation-dissipation relations for a tunnel junction driven through a resonator displaying strong quantum fluctuations. We find that the fluctuation-dissipation relations derived for classical external drives hold, provided the effect of the circuit's quantum fluctuations is incorporated into the modified nonlinear current voltage… (More)

Previous studies have shown that bone mass is significantly decreased in chronic alcoholic white patients, especially those with evidence of liver involvement. However, liver disease is an independent risk factor for bone loss. In vitro studies have shown that alcohol has a direct effect on osteoblasts. The effects of chronic alcohol consumption on bone… (More)

Transport through a one–dimensional wire of interacting electrons connected to semi–infinite leads is investigated using a bosonization approach. An incident electron is transmitted as a sequence of partial charges. The dc conduc-tance is found to be entirely determined by the properties of the leads. The dynamic nonlocal conductivity is rigorously… (More)

A microscopic theory of current partition in fractional quantum Hall liquids, described by chiral Luttinger liquids, is developed to compute the noise correlations, using the Keldysh technique. In this Hanbury-Brown and Twiss geometry, at Laughlin filling factors nu = 1/3, the real time noise correlator exhibits oscillations which persist over larger time… (More)

The current noise of a voltage biased interacting quantum wire adiabatically connected to metallic leads is computed in the presence of an impurity in the wire. We find that in the weak backscattering limit the Fano factor characterizing the ratio between noise and backscattered current crucially depends on the noise frequency omega relative to the… (More)

The slit ventricle syndrome (SVS), defined as intermittent shunt malfunction without substantial ventricular enlargement, is usually observed in shunted children with small, slitlike ventricles. This syndrome has been attributed to recurrent obstruction of the ventricular catheter, which then causes an increase of intracranial pressure. Only rarely has the… (More)

We study a homogeneous Tomonaga-Luttinger liquid with backscattering potential. A perturbative computation of the conductance at and near resonance is given. We find that the backscattering of one electron dominates that of two electrons for an interaction parameter K ≥ 1/3 and that the resonance point depends on temperature. Our results may be relevant for… (More)

We calculate the AC conductance and the finite-frequency non-symmetrized noise in interacting quantum wires and single-wall carbon nanotubes in the presence of an impurity. We observe a strong asymmetry in the frequency spectrum of the non-symmetrized excess noise, even in the presence of the metallic leads. We find that this asymmetry is proportional to… (More)
