Subject: The exactly solvable resonating valence bond liquid of the spin-1/2 Heisenberg kagome antiferromagnet

I will discuss one of the earliest examples of exactly solvable spin liquids in two spatial dimensions, introduced by G. Misguich et al back in 2002 [1] for the kagome lattice. The ground state of this model (a Rokhsar-Kiverson wavefunction) is currently believed to be adiabatically connected to the actual Z2 spin liquid ground state of the nearest-neighbor spin-1/2 Heisenberg model on the kagome, that is closely realized in herbertsmithite ZnCu3(OH)6Cl3.
