A Cluster-Based Model of the Spectrum of Erbium-Doped GdVO
Zachary H. Roberts, Masaya Hiraishi, Luke S. Trainor +1
Experimental observations of rare-earth ions doped into an antiferromagnetic crystal show an enriched optical spectrum. In this paper we present a cluster-based model to describe e…
Nuclear quadrupole interaction and zero first-order Zeeman transitions of Er in CaWO
Lewin Marsh, Yikai Yang, Cesare Mattiroli +5
We report microwave spectroscopy of Er doped in CaWO which reveals the hyperfine splitting of the erbium electronic ground state (, =15/2)…
Optical spectroscopy of single- and two-ion transitions in an antiferromagnetic stoichiometric rare-earth crystal
Masaya Hiraishi, Gabrielle A. Hunter-Smith, Gavin G. G. King +5
We characterise optical transitions of neodymium ions (Nd3+) in antiferromagnetic neodymium gallate (NdGaO3) with applied fields up to 3 T. The magnetic phase of this material has…
Coherent control of magnon-polaritons using an exceptional point
N. J. Lambert, A. Schumer, J. J. Longdell +2
The amplitude of resonant oscillations in a non-Hermitian environment can either decay or grow in time, corresponding to a mode with either loss or gain. When two coupled modes hav…
Long optical coherence times and coherent rare earth-magnon coupling in a rare earth doped anti-ferromagnet
Masaya Hiraishi, Zachary H. Roberts, Gavin G. G. King +2
Rare-earth ions are characterised by transitions with very narrow linewidths even in solid state crystals. Exceedingly long coherence times have been shown on both spin and optical…
