The Quantum spin liquid (QSL) state continues to fascinate the condensed matter community. This is because the spins in a QSL are highly entangled and fluctuate strongly down to zero temperature and, in its vicinity, novel states such as exotic forms of superconductivity emerge. However, experimental realization of QSL has proven difficult and possible systems with 2D or 3D topologies (triangular, kagome, pyrochlore) typically suffer from problems such as chemical disorder, magnetic defects, spatial or anti-symmetric DM anisotropy preventing the formation of QSL. Here, we propose to study a promising QSL candidate NaYbO2, comprising a perfect triangular lattice of Yb3+(S=1/2) ions and potentially free of these issues, using the most unambiguous technique to probe the QSL state, Inelastic Neutron Scattering.
