Our paper exploring the field dependence of the spin excitations and the formation of static order in NaYbO2 was published today in Phys. Rev. B.  This work reveals a first order phase boundary out of the field induced up-up-down state in this quantum spin liquid candidate system.  We further explore the crystal field Hamiltonian as well as the spin dynamics of the field-induced ordered state in this material.
