Visualizing the atomic-scale origin of metallic behavior in Kondo insulators
Harris Pirie, Eric Mascot, Christian E. Matt +12
A Kondo lattice is often electrically insulating at low temperatures. However, several recent experiments have detected signatures of bulk metallicity within this Kondo insulating…
Observation of Two Collapsed Phases in CaRbFe4As4
Ryan L. Stillwell, Xiangfeng Wang, Limin Wang +5
We report the observation of the pressure-induced, fully-collapsed tetragonal phase of CaRbFe4As4 for P~ 22 GPa via high-pressure x-ray diffraction and magnetotransport measurement…
Imaging emergent heavy Dirac fermions of a topological Kondo insulator
Harris Pirie, Yu Liu, A. Soumyanarayanan +12
Kondo insulators are primary candidates in the search for strongly correlated topological quantum phases, which may host topological order, fractionalization, and non-Abelian stati…
Electrical detection of surface spin polarization of candidate topological Kondo insulator SmB6
Jehyun Kim, Chaun Jang, Xiangfeng Wang +3
The Kondo insulator compound SmB6 has emerged as a strong candidate for the realization of a topologically nontrivial state in a strongly correlated system, a topological Kondo ins…
Freezing out of a low-energy bulk spin exciton in SmB6
K. Akintola, A. Pal, S. R. Dunsiger +6
The Kondo insulator SmB6 is purported to develop into a robust topological insulator at low temperature. Yet there are several puzzling and unexplained physical properties of the i…
Field-dependent heat transport in the Kondo insulator SmB6 : phonons scattered by magnetic impurities
M-E. Boulanger, F. Laliberté, M. Dion +12
The thermal conductivity of the Kondo insulator SmB was measured at low temperature, down to 70 mK, in magnetic fields up to 15 T, on single crystals grown using both the f…
