Paper: Three-Magnon Bound State in the Quasi-One-Dimensional Antiferromagnet α-NaMnO2

May 14, 2020

Our paper reporting the discovery of the first three-magnon bound state in an antiferromagnet was published today in Physical Review Letters.  This work shows that unusual quantum effects such as few-body bound states arise in the triangular lattice of classical spins in NaMnO2.  The dimensional frustration in this material yields one dimensional bound states of magnons.
