WebThis is the resonating valence bond (RVB) state of Fazekas and Anderson,4illustrated in Fig. 3. This state is a linear superposition of the very large number of possible singlet pairings between the electrons. It thus generalizes the chemical resonance of ˇ-bonds in the benzene ring to an in nite number of electrons on a lattice.

(RVB) states emerging at low energies, including gapped and gapless spin liquids and valence bond crystals. Here we revisit the crossover from this quantum RVB phase to a semiclassical regime brought about by anisotropic Kitaev interactions, and In condensed matter physics, the resonating valence bond theory (RVB) is a theoretical model that attempts to describe high-temperature superconductivity, and in particular the superconductivity in cuprate compounds. It was first proposed by an American physicist P. W. Anderson and Indian theoretical physicist Ganapathy Baskaran in 1987. The theory states that in copper oxide lattices, electrons from neighboring copper atoms interact to form a valence bond, which locks them in pl…
