Abstract

In the many particle physics the exact diagonalization (ED) is limited to small system sizes, like 4×4, on account of the restrictions of the computer memory. Whereas the stochastic diagonalization (SD) and the projector quantum Monte Carlo (PQMC) are not limited to a certain system size the limits in the parameter space of the analyzed physical model are at hoc not clear. For the ...
