WebRVB states exhibit neither the standard antiferromagnetic Néel order, nor the spin-Peierls order (for which singlet pairs are ordered in space). Recent extensive numerical studies have shown that the RVB physics characterizes the spin 1/2 Heisenberg antiferromagnet on the 2D Kagomé lattice in 2D (see Fig. 1a) waldmann ; moessner . WebQuantum dimer models were introduced to model the physics of resonating valence bond (RVB) states in lattice spin systems. The only degrees of freedom retained from the …

WebThe RVB state is a superposition of all different singlet pairings, of which only one is shown above. 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 π -bonds in the benzene ring to an infinite number of electrons on a lattice. condos in hatboro horsham areaWebInnovative design, advanced comfort.

As much as such directions are tempting, one must proceed with due caution since the experimental situa-tion is rather complex. As discussed shortly, the sys-tem is actually away from the vicinity of half-filling, the regime where RVB physics is considered to be valid. It is reasonable then to resort to generic methods no more condos in hatteras villageWebIn this work, we propose a simple picture for these spectral anomalies by invoking the resonating valence bond (RVB) physics in the description of the ground state of the system.
