The authors report the observation of plasmons that exhibit quantized velocities in carbon nanotubes.
We present high resolution angle resolved photoemission spectroscopy (ARPES) data for K0.3MoO3 (blue bronze) and propose a… Expand Injection of spin-polarized electrons into a superconductor leads to both spin and charge imbalance. If charge relaxation occurs… Expand Quantum dots are model systems for quantum thermoelectric behavior because of their ability to control and measure the effects of… Expand We demonstrate that a recently introduced slave-boson mean-field theory is equivalent to our Gutzwiller theory for multi-band… Expand We combine the first-quantized path-integral formalism and bosonization to develop a phenomenological theory for spin-charge… Expand We study the spin-charge separation in a Kondo-like model for an impurity with a spin and a charge (isospin) degree of freedom… Expand We show within the slave-boson mean field approximation that the two-dimensional t - J model has an intrinsic instability toward… Expand The conductance through two quantum dots in series is studied using general qualitative arguments and quantitative slave-boson… Expand The slave-boson mean-field method is used to study the two-dimensional Hubbard model. A magnetic phase diagram allowing for… Expand
