Author(s): Sofia-Michaela Souliou, Jiří Chaloupka, Giniyat Khaliullin, Gihun Ryu, Anil Jain, B. J. Kim, Matthieu Le Tacon, and Bernhard Keimer We present and analyze Raman spectra of the Mott insulator Ca 2 RuO 4 , whose quasi-two-dimensional antiferromagnetic order has been described as a condensate of low-lying spin-orbit excitons with angular momentum J eff = 1 . In the A g polarization geometry, the amplitude (Higgs) mode of the spin-orbit cond... [Phys. Rev. Lett. 119, 067201] Published Tue Aug 08, 2017
