    "abstract": "Starting from the canonical ensemble over the space of pure quantum states,\nwe obtain an integral representation for the partition function. This is used\nto calculate the magnetisation of a system of N spin-1/2 particles. The results\nsuggest the existence of a new type of first order phase transition that occurs\nat zero temperature in the absence of spin-spin interactions. The transition\narises as a consequence of quantum entanglement. The effects of internal\ninteractions are analysed and the behaviour of the magnetic susceptibility for\na small number of interacting spins is determined.",
