Quantum and Classical Phases of the Pyrochlore Heisenberg Model with Competing Interactions
We investigate the quantum Heisenberg model on the pyrochlore lattice for a generic spin S in the presence of nearest-neighbor J_{1} and second-nearest-neighbor J_{2} exchange interactions. By employing the pseudofermion functional renormalization group method, we find, for S=1/2 and S=1, an extende...
