abstract = {We report thermodynamic and neutron scattering measurements
of the triangular-lattice quantum Ising magnet TmMgGaO4 in
longitudinal magnetic fields. Our experiments reveal a
quasi-plateau state induced by quantum fluctuations. This
state exhibits an unconventional non-monotonic field and
temperature dependence of the magnetic order and excitation
gap. In the high field regime where the quantum fluctuations
are largely suppressed, we observed a disordered state with
coherent magnon-like excitations despite the suppression of
the spin excitation intensity. Through detailed
semi-classical calculations, we are able to understand these
behaviors quantitatively from the subtle competition between
quantum fluctuations and frustrated Ising interactions.},
