Topological surface states in the Kondo insulator YbB revealed via planar tunneling spectroscopy
A. Gupta, A. Weiser, L. H. Greene +8
Planar tunneling spectroscopy of the Kondo insulator SmB suggests that an interaction between the surface Dirac fermions and the bulk spin excitons results in incompletely prot…
Topological nature of the Kondo insulator SmB and its sensitiveness to Sm vacancy
W. K. Park, J. A. Sittler, L. H. Greene +5
The true topological nature of the Kondo insulator SmB remains to be unveiled. Our previous tunneling study not only found evidence for the existence of surface Dirac fermions,…
Origin of gap-like behaviors in URuSi: Combined study via quasiparticle scattering spectroscopy and resistivity measurements
S. Zhang, G. Chappell, N. Pouse +4
We address two long-standing questions regarding the hidden order in URu2Si2: Is it associated with the hybridization process, and what are the distinct roles played by the localiz…
Topological surface states interacting with bulk excitations in the Kondo insulator SmB revealed via planar tunneling spectroscopy
Wan Kyu Park, Lunan Sun, Alexander Noddings +3
Samarium hexaboride (SmB), a well-known Kondo insulator in which the insulating bulk arises from strong electron correlations, has recently attracted great attention owing to i…
Recent Progress of Point Contact Spectroscopy as a Probe of Correlated Electron States
Wei-Cheng Lee, Laura H. Greene
We review recent progress in point contact spectroscopy (PCS) to extract spectroscopic information out of correlated electron materials, with the emphasis on non-superconducting st…
Theory of Point Contact Spectroscopy in Correlated Materials
Wei-Cheng Lee, Wan Kyu Park, Hamood Z. Arham +2
We develop a microscopic theory for the point-contact conductance between a metalic electrode and a strongly correlated material using the non-equilibrium Schwinger-Kadanoff-Baym-K…
