Constructing a Gapless Spin-Liquid State for the Spin-1/2 J[subscript 1]-J[subscript 2] Heisenberg Model on a Square Lattice
We construct a class of projected entangled pair states which is exactly the resonating valence bond wave functions endowed with both short range and long range valence bonds. With an energetically preferred resonating valence bond pattern, the wave function is simplified to live in a one-parameter...
