Electronic and Vibrational Excitations on the Surface of the Three-Dimensional Topological Insulator BiTeSe (x = 0, 2, 3)
A. Lee, H. -H. Kung, Xueyun Wang +2
We study surface states in the three-dimensional topological insulators BiTeSe (x = 0, 2, 3) by polarization resolved resonant Raman spectroscopy. By tracking the…
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…
Optical manipulation of Rashba-split 2-Dimensional Electron Gas
M. Michiardi, F. Boschini, H. -H. Kung +11
In spintronic devices, the two main approaches to actively control the electrons' spin degree of freedom involve either static magnetic or electric fields. An alternative avenue re…
Extremely large magnetoresistance from electron-hole compensation in the nodal loop semimetal ZrP
J. Bannies, E. Razzoli, M. Michiardi +10
Several early transition metal dipnictides have been found to host topological semimetal states and exhibit large magnetoresistance. In this study, we use angle-resolved photoemiss…
Observation of Chiral Surface Excitons in a Topological Insulator BiSe
H. -H. Kung, A. P. Goyal, D. L. Maslov +5
The protected electron states at the boundaries or on the surfaces of topological insulators (TIs) have been the subject of intense theoretical and experimental investigations. Suc…
Raman spectroscopy of -electron metals: an example of CeB
Mai Ye, H. -H. Kung, Priscila F. S. Rosa +3
We performed an optical spectroscopy study of electronic and magnetic excitations for a rare-earth system with a single electron quasi-localized in the f-shell on an ion at high-sy…
Intrinsic Insulating Ground State in Transition Metal Dichalcogenide TiSe2
Daniel J. Campbell, Chris Eckberg, Peter Y. Zavalij +8
The transition metal dichalcogenide TiSe has received significant research attention over the past four decades. Different studies have presented ways to suppress the 200~K cha…
Anomalous magneto-elastic coupling in Au-doped BaFe2As2
S. -F. Wu, W. -L. Zhang, L. Li +6
We used polarization-resolved Raman scattering to study magneto-elastic coupling in Ba(FeAu)As crystals as a function of light Au-doping, materials for which…
Chiral Spin Mode on the Surface of a Topological Insulator
H. -H. Kung, S. Maiti, X. Wang +3
Using polarization-resolved resonant Raman spectroscopy, we explore collective spin excitations of the chiral surface states in a three dimensional topological insulator, BiSe$…
Surface vibrational modes of the topological insulator BiSe observed by Raman spectroscopy
H. -H. Kung, M. Salehi, I. Boulares +10
We present polarization resolved Raman scattering study of surface vibration modes in the topological insulator BiSe single crystal and thick films. Besides the four Raman…
Analogy between the "Hidden Order" and the Orbital Antiferromagnetism in URuFeSi
H. -H. Kung, S. Ran, N. Kanchanavatee +6
We study URuFeSi, in which two types of staggered phases compete at low temperature as the iron concentration is varied: the nonmagnetic "hidden order" (HO) pha…
