The one-dimensional Ising model is a simplified mathematical model used in statistical mechanics to study phase transitions and magnetism in a linear chain of spins. It consists of a linear arrangement of discrete spins, which can take on two values up(+1) and down (-1). These spins interact with their nearest neighbors through an energy term that encourages alignment or anti-alignment. This model is solvable by using techniques such as the transfer matrix and the Onsager solution. I have followed the transfer matrix techniques. The most important feature of this video is the explanation of the fact that the one-dimensional Ising model does not exhibit Ferromagnetism.
