An effect of Sm vacancies on the hybridization gap in topological Kondo insulator candidate SmB
Michael E. Valentine, Seyed Koohpayeh, W. Adam Phelan +4
A necessary element for the predicted topological state in Kondo insulator SmB is the hybridization gap which opens in this compound at low temperatures. In this work, we prese…
Impurities or a neutral Fermi surface? A further examination of the low-energy ac optical conductivity of SmB
N. J. Laurita, C. M. Morris, S. M. Koohpayeh +3
Recent experiments have uncovered evidence of low energy excitations in the bulk of SmB that are perhaps associated with unconventional quasiparticles, bringing into question w…
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…
Incommensurate magnetism near quantum criticality in CeNiAsO
Shan Wu, W. A. Phelan, L. Liu +14
Two phase transitions in the tetragonal strongly correlated electron system CeNiAsO were probed by neutron scattering and zero field muon spin rotation. For = 8.7(3) K,…
Quantum oscillations and a non-trivial Berry phase in the noncentrosymmetric superconductor BiPd
Mojammel A. Khan, D. E. Graf, D. Browne +4
We report the measurements of de Haas-van Alphen (dHvA) oscillations in the noncentrosymmetric superconductor BiPd. Several pieces of a complex multi-sheet Fermi surface are identi…
