Spectral And Dynamical Properties Of Strongly Correlated Systems
... variance with bosons, often uncontrolled approximations need to be introduced in their simulation. Fermions do however constitute a substantial part of the matter surrounding us and the description of most phenomena due to strong correlation suffers from the approximations needed in their numerical ...
