Doped Bosonic and Fermionic Resonating Valence Bond States
summary
Constructs a fermionic RVB wavefunction by rewriting the equal‑weight dimer PEPS in a fermion basis and adding two local projector terms (P1, P2) with variational parameters D=3 PEPS on infinite cylinders (transverse 6–8) so the bond dimension stays fixed. Doping immediately produces U(1) symmetry breaking and a superconducting state with nearest‑neighbor d‑wave plus a small i s component, pairing amplitude scaling roughly pairing amplitude ~ sqrt(doping), and kinetic energy per hole as low as kinetic energy ~ -2.5 t per hole matching exact/DMRG benchmarks.
