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…

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…
