The dimer-RVB State of the Four-Leg Heisenberg Ladder: Interference among Resonances

Abstract

We study the ground state of the 4-leg spin ladder using a dimer-RVB ansatz and the Lanczos method. Besides the well known resonance mechanism between valence bond configurations we find novel interference effects among nearby resonances.
