Quantum and Classical Phases of the Pyrochlore Heisenberg Model with Competing Interactions

Yasir Iqbal, Tobias Müller, Pratyay Ghosh +5

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 $J_2$ exchang…
