On the absence of actual plateaus in zero-temperature magnetization curves of quantum spin clusters and chains
Vadim Ohanyan, Onofre Rojas, Jozef Strecka +1
We examine the general features of the non-commutativity of the magnetization operator and Hamiltonian for the small quantum spin clusters. The source of this non-commutativity can…
Modulation of Luttinger liquid exponents in multi-walled carbon nanotubes
S. Bellucci, J. Gonzalez, P. Onorato +1
We develop in this paper a theoretical framework that applies to the intermediate regime between the Coulomb blockade and the Luttinger liquid behavior in multi-walled carbon nanot…
Magnetic field effects and renormalization of the long-range Coulomb interaction in Carbon Nanotubes
S. Bellucci, P. Onorato
We develop two theoretical approaches for dealing with the low-energy effects of the repulsive interaction in one-dimensional electron systems. Renormalization Group methods allow…
Magnetic field effects on low dimensional electron systems: Luttinger liquid behaviour in a Quantum Wire
S. Bellucci, P. Onorato
We discuss the effects of a strong magnetic field in Quantum Wires. We show how the presence of a magnetic field modifies the role played by % which %coefficients corresponding to…
Crossover from Luttinger liquid to Coulomb blockade regime in carbon nanotubes
S. Bellucci, J. Gonzalez, P. Onorato
We develop a theoretical approach to the low-energy properties of 1D electron systems aimed to encompass the mixed features of Luttinger liquid and Coulomb blockade behavior observ…
Doping- and size-dependent suppression of tunneling in carbon nanotubes
S. Bellucci, J. Gonzalez, P. Onorato
We study the effect of doping in the suppression of tunneling observed in multi-walled nanotubes, incorporating as well the influence of the finite dimensions of the system. A scal…
