Low-Energy Properties of Antiferromagnetic Spin-1/2 Heisenberg Ladders with an Odd Number of Legs
Beat Frischmuth, Stephan Haas, German Sierra +1
An effective low-energy description for multi-leg spin-1/2 Heisenberg ladders with an odd number of legs is proposed. Using a newly developed Monte Carlo loop algorithm and exact d…

A Rotating-Valence-Bond scenario for the 2D Antiferromagnetic Heisenberg Model
German Sierra, Miguel A. Martin-Delgado
We propose that the valence bonds forming the ground state of the 2D-AF Heisenberg model on a square lattice may rotate under the effect of the antiferromagnetic background. To tes…
