Tomonaga-Luttinger liquid features in ballistic single-walled carbon nanotubes: conductance and shot noise.

چکیده
We study the electrical transport properties of well-contacted ballistic single-walled carbon nanotubes in a three-terminal configuration at low temperatures. We observe signatures of strong electron-electron interactions: the conductance exhibits bias-voltage-dependent amplitudes of quantum interference oscillation, and both the current noise and Fano factor manifest bias-voltage-dependent power-law scalings. We analyze our data within the Tomonaga-Luttinger liquid model using the nonequilibrium Keldysh formalism and find qualitative and quantitative agreement between experiment and theory.

Correlated Electron Transport in One-dimensional Mesoscopic Conductors
Mesoscopic systems have emerged as a result of advanced microfabrication processing. These systems provide a new playground where tailor-made structures are available. This enables the study of quantum phenomena due to dimensional confinement and manipulation of system geometries. Two specific systems are investigated in this dissertation: single-walled carbon nanotubes and quantum point contac...
متن کاملMeasuring Fractional Charge in Carbon Nanotubes
The Luttinger model of the one-dimensional Fermi gas is the cornerstone of modern understanding of interacting electrons in one dimension. In fact, the enormous class of systems whose universal behavior is adiabatically connected to it are now deemed Luttinger liquids. Recently, it has been shown that metallic single-walled carbon nanotubes are almost perfectly described by the Luttinger Hamilt...
متن کاملTransport through a double barrier in Large Radius Carbon Nanotubes in the presence of a transverse magnetic field
We discuss the Luttinger Liquid behaviour of Large Radius Carbon Nanotube e.g. the Multi Wall ones (MWNT), under the action of a transverse magnetic field B. Our results imply a reduction with B in the value of the bulk critical exponent, αbulk, for the tunneling density of states, which is in agreement with that observed in transport experiments. Then, the problem of the transport through a Qu...
متن کاملTomonaga–Luttinger physics in electronic quantum circuits
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 circuit. In particular, the conductances ar...
متن کاملObservation of phase transition from Tomonaga-Luttinger liquid states to superconductive phase in carbon nanotubes
We report the observation of change in one-dimensional Coulomb interaction between electrons in multi-walled carbon nanotubes (MWNTs). The results indicate occurrence of the phase transition from the Tomonaga-Luttinger liquid (TLL) states within repulsive Coulomb interaction to the superconductive (SC) phase within attractive Coulomb interaction mediated by phonon, as energy decreases. The smal...
