Competition Between Antiferromagnetic Order and Spin-Liquid Behavior in the Two-Dimensional Periodic Anderson Model at Half-Filling
M. Vekic, J. W. Cannon, D. J. Scalapino +2
We study the two-dimensional periodic Anderson model at half-filling using quantum Monte Carlo (QMC) techniques. The ground state undergoes a magnetic order-disorder transition as…

Disorder Induced Phase Transition in a Random Quantum Antiferromagnet
Anders W. Sandvik, Marco Vekic
A two-dimensional Heisenberg model with random antiferromagnetic nearest-neighbor exchange is studied using quantum Monte Carlo techniques. As the strength of the randomness is inc…

Dynamically Triangulated Ising Spins in Flat Space
Marco Vekic, Shao Liu, Herbert W. Hamber
A model describing Ising spins with short range interactions moving randomly in a plane is considered. In the presence of a hard core repulsion, which prevents the Ising spins from…
