Gutzwiller projected BCS states are a physically transparent representation of a resonating valence bond (RVB) spin liquid. Here we show that this class of wave functions provides a very accurate ansatz of the non-magnetic phase of the J1−J2 Heisenberg model. This wave function is proposed to represent the generic spin-half RVB ground state in spin liquids.

Abstract
Gutzwiller projected BCS states are a physically transparent representation of a resonating valence bond (RVB) spin liquid. Here we show that this class of wave functions provides a very accurate ansatz of the non-magnetic phase of the J1−J2 Heisenberg model. This wave function is proposed to represent the generic spin-half RVB ground state in spin liquids.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
