Solving strongly correlated quantum many-body system is one of the challenges in condensed matter theory. Inspired by the density matrix renormalization group (DMRG) method for 1d systems, tensor network states (TNSs) have been proposed to solve the strongly correlated quantum many-body systems in 2 and higher dimension. In this talk I will introduce one class among many of tensor network states, the so called projected entangled pair states (PEPSs). I will sketch the basic idea of dealing with tensor network states. In the last, examples will be given regarding to the advantages of the tensor network states method over Quantum Monte Carlo and DMRG methods. |
