Low-Energy Excitations and Ground State Selection in Quantum Breathing Pyrochlore Antiferromagnet Ba${}_3$Yb${}_2$Zn${}_5$O${}_{11}$

T. Haku, K. Kimura, Y. Matsumoto +10

We study low energy excitations in the quantum breathing pyrochlore antiferromagnet Ba${}_3$Yb${}_2$Zn${}_5$O${}_{11}$ by combination of inelastic neutron scattering (INS) and thermodynami…
