magnon' excitations into spin-1/2
spinon' excitations, which qualitatively explain the experimentally observed quantum anomaly, demand further investigation into this novel wave function.
Theoretical framework involving construction of a Gutzwiller projected staggered flux state, a wavefunction depending on variational parameters, is developed. A numerical method based on MonteCarlo simulation is used to optimize the variational wave function and calculate the relevant physical observables. Exploring the gradual evolution of these observables with the coupling ratio provides us with a clear picture of the evolution of spin excitations on this RVB state, as the dimensionality of the model is changed from 1D to 2D.
