This textbook provides a thorough introduction to phase transitions and exactly solved models in statistical physics and quantum field theory. It covers a broad area from basic concepts of statistical physics and quantum mechanics to latest developments in low dimensional quantum field theories, phase transitions and non-perturbative analysis.
