Bose-Einstein condensation of a two-magnon bound state in a spin-one triangular lattice
Jieming Sheng, Jia-Wei Mei, Le Wang +31
In ordered magnets, the elementary excitations are spin waves (magnons), which obey Bose-Einstein statistics. Similarly to Cooper pairs in superconductors, magnons can be paired in…
