Field and Polarization Dependent Quantum Spin Dynamics in Honeycomb Magnet Na${}_2$Co${}_2$TeO${}_6$: Magnetic Excitations and Continuum

Patrick Pilch, Laur Peedu, Anup Kumar Bera +4

We report terahertz spectroscopic measurements of quantum spin dynamics in the spin-1/2 honeycomb magnet Na${}_2$Co${}_2$TeO${}_6$ as a function of applied magnetic field with different…
