This thesis uses generalized ensembles Monte Carlo methods to explore the critical behavior of spin chains with algebraically decaying interactions. The first part of this thesis investigates the phase diagram of a long-range Potts chain using a multicanonical algorithm. A new method based on spinodal points is proposed to detect the order of phase transitions. The boundary between first- and second-order transitions is located with unprecedented accuracy using this method, and a new, unusual… Expand

It is found that the boundary with short-range critical behavior occurs for interactions depending on distance r as r(-15/4), which answers a long-standing controversy between mutually conflicting renormalization-group analyses. Expand
