A Tale of Two Theories: Quantum Griffiths Effects in Metallic Systems

A. H. Castro Neto, B. A. Jones

We show that two apparently contradictory theories on the existence of Griffiths-McCoy singularities in magnetic metallic systems [1,2] are in fact mathematically equivalent. We di…

Quantum three-coloring dimer model and the disruptive effect of quantum glassiness on its line of critical points

Claudio Castelnovo, Claudio Chamon, Christopher Mudry +2

We construct a quantum extension of the (classical) three-coloring model introduced by Baxter [J.Math.Phys.11, 784 (1970)] for which the ground state can be computed exactly along…

Quantum Glassiness

Claudio Chamon

Describing matter at near absolute zero temperature requires understanding a system's quantum ground state and the low energy excitations around it, the quasiparticles, which are t…

Double Exchange Model for Magnetic Hexaborides

Vitor M. Pereira, J. M. B. Lopes dos Santos, Eduardo V. Castro +1

A microscopic theory for rare-earth ferromagnetic hexaborides, such as Eu(1-x)Ca(x)B6, is proposed on the basis of the double-exchange Hamiltonian. In these systems, the reduced ca…

Impurity effects at finite temperature in the two-dimensional S=1/2 Heisenberg antiferromagnet

Kaj H. Hoglund, Anders W. Sandvik

We discuss effects of various impurities on the magnetic susceptibility and the specific heat of the quantum S=1/2 Heisenberg antiferromagnet on a two-dimensional square lattice. F…

Excitations and Quantum Fluctuations in Site Diluted Two-Dimensional Antiferromagnets

Eduardo R. Mucciolo, A. H. Castro Neto, C. Chamon

We study the effect of site dilution and quantum fluctuations in an antiferromagnetic spin system on a square lattice within the linear spin-wave approximation. By performing numer…

Theory of the Magnetic phase diagram of LiHoF

P. B. Chakraborty, P. Henelius, H. Kjønsberg +2

The properties of LiHoF are believed to be well described by a long-range dipolar Ising model. We go beyond mean-field theory and calculate the phase diagram of the Ising model…

Ground state phases of the Half-Filled One-Dimensional Extended Hubbard Model

A. W. Sandvik, L. Balents, D. K. Campbell

Using quantum Monte Carlo simulations, results of a strong-coupling expansion, and Luttinger liquid theory, we determine quantitatively the ground state phase diagram of the one-di…

Susceptibility and Dzyaloshinskii-Moriya interaction in the Haldane gap compound NENP

Hai Huang, Ian Affleck

The Haldane gap material NENP exhibits anomalies in its Knight shift, far infrared absorption and field-dependent gaps, which have been explained using the staggered -tensor tha…

Edge States in Doped Antiferromagnetic Nano-Structures

A. L. Chernyshev, A. H. Castro Neto, S. R. White

We study competition between different phases in a strongly correlated nano-structure with an edge. Making use of the self-consistent Green's function and density matrix renormaliz…
