Spin systems are among the most studied systems in statistical physics. Originally introduced in very simple forms to explain the behaviour of magnetic materials, they have been used extensively to understand critical phenomena and phase transitions. Over time, many other models have been mapped onto spin models, which has made their solution possible.

Today, the role of spin systems in physics goes far beyond the description of magnetic materials. They have found applications in a wide range of problems: from quantum entanglement to models of economic systems, from brain models and the problem of consciousness to social dynamics, and from models of information theory to artificial neural networks. Spin systems are increasingly the subject of interdisciplinary research.

Our research group in the Department of Physics, Faculty of Science, Dokuz Eylül University, works on spin systems and has been studying their application, mainly to magnetic models, since 2012.
