✦ Synopsis

Quantum Monte Carlo results for both the repulsive and attractive Hubbard model on a square lattice are discussed. Results on pairing correlation in the repulsive Hubbard model are summarized. Momentum distribution function in the attractive Hubbard model is presented and compared with mean field results.
