Observation of phase transition from Tomonaga-Luttinger liquid states to superconductive phase in carbon nanotubes
نویسنده
چکیده
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 small number of shells with current flow in the partially end-bonded MWNTs makes the observation possible.

Transition from a Tomonaga-Luttinger liquid to a fermi liquid in potassium-intercalated bundles of single-wall carbon nanotubes.
We report on the first direct observation of a transition from a Tomonaga-Luttinger liquid to a Fermi-liquid behavior in potassium-intercalated mats of single-wall carbon nanotubes. Using high resolution photoemission spectroscopy, an analysis of the spectral shape near the Fermi level reveals a Tomonaga-Luttinger liquid power law scaling in the density of states for the pristine sample and for...
متن کاملTomonaga–Luttinger parameters for doped Mott insulators
– The Tomonaga–Luttinger parameter Kρ determines the critical behavior in quasi one-dimensional correlated electron systems, e.g., the exponent α for the density of states near the Fermi energy. We use the numerical density-matrix renormalization group method to calculate Kρ from the slope of the density-density correlation function in momentum space at zero wave vector. We check the accuracy o...
متن کاملHigh-Tc Superconductivity in Entirely End-bonded Multi-walled nanotubes
One-dimensional (1D) systems face some obstructions that prevent the emergence of superconductivity, such as Tomonaga-Luttinger liquid states and Peierls transition. Carbon nanotubes (CNs) are one of the best candidates for investigating the possibility of 1D superconductivity and its interplay with such obstructions. Only two groups to our knowledge, however, have experimentally reported super...
متن کاملTomonaga-Luttinger liquid features in ballistic single-walled carbon nanotubes: conductance and shot noise.
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 pow...
متن کاملSpin gap and Luttinger liquid description of the NMR relaxation in carbon nanotubes.
Recent NMR experiments by Singer et al. [Singer, Phys. Rev. Lett. 95, 236403 (2005).] showed a deviation from Fermi-liquid behavior in carbon nanotubes with an energy gap evident at low temperatures. Here, a comprehensive theory for the magnetic field and temperature dependent NMR 13C spin-lattice relaxation is given in the framework of the Tomonaga-Luttinger liquid. The low temperature propert...
