Anisotropy of Kondo-lattice coherence in momentum space for CeCoIn5
Mai Ye, Hsiang-Hsi Kung, Priscila F. S. Rosa +3
We study the electronic and phononic excitations of heavy-fermion metal CeCoIn by polarization-resolved Raman spectroscopy to explore the Kondo-lattice coherence. Below the coh…
Chiral Electronic Excitations in a Quasi-2D Rashba System BiTeI
A. C. Lee, B. Peng, K. Du +5
The optical transitions between spin-polarized bands of the quasi-two dimensional Rashba system BiTeI are investigated using polarization resolved resonant Raman spectroscopy. We d…
Charge density wave order in kagome metal AVSb (A= Cs, Rb, K)
Shangfei Wu, Brenden R. Ortiz, Hengxin Tan +4
We employ polarization-resolved electronic Raman spectroscopy and density functional theory to study the primary and secondary order parameters, as well as their interplay, in the…
Crystal-field excitations and vibronic modes in triangular-lattice spin-liquid candidate TbInO
Mai Ye, Xianghan Xu, Xiangyue Wang +3
We study the ground state properties, the electronic excitations and lattice dynamics in spin-liquid candidate TbInO. By employing polarization resolved Raman spectroscopy we d…
Failed excitonic quantum phase transition in TaNi(SeS)
Pavel A. Volkov, Mai Ye, Himanshu Lohani +3
We study the electronic phase diagram of the excitonic insulator candidates TaNi(SeS) [x=0, ... ,1] using Raman spectroscopy. Critical excitonic fluctuations ar…
Comment on "Direct observation of excitonic instability in TaNiSe" [arXiv:2007.08212 (2020)]
G. Blumberg
The origin of the second order phase transition at 328K in TaNiSe, a prominent candidate for direct gap excitonic insulator, remains under fervent debate. The driving force…
