d-Mott phases in one and two dimensions
A. Laeuchli, C. Honerkamp, T. M. Rice
We use exact diagonalization to determine the spectrum of reduced Hamiltonians based on renormalization group flows to strong coupling. For the half-filled two-leg Hubbard ladder w…
The transition between hole-pairs and four-hole clusters in four-leg tJ ladders
Thomas Siller, Matthias Troyer, T. M. Rice +1
Holes weakly doped into a four-leg \tj ladder bind in pairs. At dopings exceeding a critical doping of four hole clusters are observed to form in DMRG calculation…
Li Induced Spin and Charge Excitations in a Spin Ladder
Andreas Laeuchli, Didier Poilblanc, T. M. Rice +1
A lithium dopant in a cuprate spin ladder acts as a vacant (non-magnetic) site accompanied by an extra hole bound by a Coulomb potential. We find that, although the undoped ladder…
Acoustic Plasmons in MgB2
K. Voelker, V. I. Anisimov, T. M. Rice
We present strong evidence for the existence of an acoustic plasmon mode, that is, a quadrupolar charge collective mode with linear dispersion, in MgB2. This mode may be responsibl…
Interband proximity effect and nodes of superconducting gap in Sr2RuO4
M. E. Zhitomirsky, T. M. Rice
The power-law temperature dependences of the specific heat, the nuclear relaxation rate, and the thermal conductivity suggest the presence of line nodes in the superconducting gap…
Localization in ruthenates: magnetic and electronic properties of Ca(2-x)Sr(x)RuO(4)
V. I. Anisimov, I. A. Nekrasov, D. E. Kondakov +2
The electronic structures of the metallic and insulating phases of Ca(2-x)Sr(x)RuO(4) (0<= x <= 2) are calculated using LDA, LDA+U and Dynamical Mean-Field Approximation methods. F…
