Quantum fluctuations of a nearly critical Heisenberg spin glass
Quantum fluctuations of a nearly critical Heisenberg spin glass
We describe the interplay of quantum and thermal fluctuations in the infinite-range Heisenberg spin glass. This model is generalized to SU(N) symmetry, and we describe the phase diagram as a function of the spin S and the temperature T. The model is solved in the large N limit and certain …
