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…
Spectroscopic Evidence for the Direct Involvement of Local Moments in the Pairing Process of the Heavy-Fermion Superconductor CeCoIn
K. Shrestha, S. Zhang, L. H. Greene +5
The microscopic mechanism for electron pairing in heavy-fermion superconductors remains a major challenge in quantum materials. Some form of magnetic mediation is widely accepted w…
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…
Design and construction of a point-contact spectroscopy rig with lateral scanning capability
M. Tortello, W. K. Park, C. O. Ascencio +2
The design and realization of a cryogenic rig for point-contact spectroscopy measurements in the needle-anvil configuration is presented. Thanks to the use of two piezoelectric nan…
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…
