One-Particle Spectral Properties of 1D Mott-Hubbard Insulators
J. M. P. Carmelo, J. M. E. Guerra, J. M. B. Lopes dos Santos +1
We use an exact {\it holon} and {\it spinon} Landau-liquid functional which describes the holon - spinon interactions at all scattering orders, to study correlation functions of in…
Effective Field Theory for Layered Quantum Antiferromagnets with Non-Magnetic Impurities
Y. C. Chen, A. H. Castro Neto
We propose an effective two-dimensional quantum non-linear sigma model combined with classical percolation theory to study the magnetic properties of site diluted layered quantum a…
Mobility of Bloch Walls via the Collective Coordinate Method
M. A. Despósito, A. Villares Ferrer, A. O. Caldeira +1
We have studied the problem of the dissipative motion of Bloch walls considering a totally anisotropic one dimensional spin chain in the presence of a magnetic field. Using the so-…
