SUPER-EFFECTIVE FIELD THEORY AND EXOTIC PHASE TRANSITIONS IN SPIN SYSTEMS

Abstract
The ordinary mean-field approximation is extremely extended so that even exotic phase transitions such as spin glasses and chiral orders may be treated analytically. This new scheme is very powerful even in estimating true fractional critical exponents, if we combine this with the coherent-anomaly method (CAM).
