Comment on "Gapless Spin-1 Neutral Collective Mode Branch for Graphite"
N. M. R. Peres, M. A. N. Araujo, A. H. Castro Neto
Comment on "Gapless Spin-1 Neutral Collective Mode Branch for Graphite" by G. Baskaran and S.A. Jafari [cond-mat/0110022; Physical Review Letters, 89, 016402 (2002)].
Quasi-Particle Spectra, Charge-Density-Wave, Superconductivity and Electron-Phonon Coupling in 2H-NbSe2
T. Valla, A. V. Fedorov, P. D. Johnson +5
High-resolution photoemission has been used to study the electronic structure of the charge density wave (CDW) and superconducting (SC) dichalcogenide, 2H- NbSe2. From the extracte…
Interplay between disorder, quantum and thermal fluctuations in ferromagnetic alloys: The case of UCu2Si(2-x)Ge(x)
M. B. Silva Neto, A. H. Castro Neto, D. Mixson +2
We consider, theoretically and experimentally, the effects of structural disorder, quantum and thermal fluctuations in the magnetic and transport properties of certain ferromagneti…
Potential Flow of Renormalization Group in Quasi-One-Dimensional Systems
Wei Chen, Ming-Shyang Chang, Hsiu-Hau Lin +2
We address the issue why the phase diagrams for quasi-one-dimensional systems are rather simple, while the renormalization group equations behind the scene are non-linear and messy…
Junctions of three quantum wires and the dissipative Hofstadter model
Claudio Chamon, Masaki Oshikawa, Ian Affleck
We study a junction of three quantum wires enclosing a magnetic flux. This is the simplest problem of a quantum junction between Tomonaga-Luttinger liquids in which Fermi statistic…
Quantum Magnetic Impurities in Magnetically Ordered Systems
A. H. Castro Neto, E. Novais, L. Borda +2
We discuss the problem of a spin 1/2 impurity immersed in a spin S magnetically ordered background. We show that the problem maps onto a generalization of the dissipative two level…
Scaling Study of the Metal-Insulator Transition in one-Dimensional Fermion Systems
Shi-Jian Gu, Vitor M. Pereira, N. M. R. Peres
We consider the Ising phase of the antiferromagnetic XXZ Heisenberg chain on a finite-size lattice with N sites.We compute the large behavior of the spin stiffness, obtaining t…
Peierls transition in the presence of finite-frequency phonons in the one-dimensional extended Peierls-Hubbard model at half-filling
P. Sengupta A. W. Sandvik, D. K. Campbell
We report quantum Monte Carlo (stochastic series expansion) results for the transition from a Mott insulator to a dimerized Peierls insulating state in a half-filled, 1D extended H…
Local Magnetic Susceptibility of the Positive Muon in the Quasi 1D S=1/2 Antiferromagnet dichlorobis (pyridine) copper (II)
J. A. Chakhalian, R. F. Kiefl, R. Miller +9
We report muon spin rotation measurements of the local magnetic susceptibility around a positive muon in the paramagnetic state of the quasi one-dimensional spin 1/2 antiferromagne…
Comment on ``Ground State Phase Diagram of a Half-Filled One-Dimensional Extended Hubbard Model''
A. W. Sandvik, P. Sengupta, D. K. Campbell
In Phys. Rev. Lett. 89, 236401 (2002), Jeckelmann argued that the recently discovered bond-order-wave (BOW) phase of the 1D extended Hubbard model does not have a finite extent in…
