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,…
-axis transport in UTe: Evidence of Three Dimensional Conductivity Component
Yun Suk Eo, Shouzheng Liu, Shanta R. Saha +13
We study the temperature dependence of electrical resistivity for currents directed along all crystallographic axes of the spin-triplet superconductor UTe. We focus particula…
Bulk transport paths through defects in floating zone and Al flux grown SmB
Yun Suk Eo, Alexa Rakoski, Shriya Sinha +16
We investigate the roles of disorder on low-temperature transport in SmB crystals grown by both the Al flux and floating zone methods. We used the inverted resistance method wi…
Pristine quantum criticality in a Kondo semimetal
W. T. Fuhrman, A. Sidorenko, J. Hänel +8
The observation of quantum criticality in diverse classes of strongly correlated electron systems has been instrumental in establishing ordering principles, discovering new phases,…
Anomalous normal fluid response in a chiral superconductor UTe2
Seokjin Bae, Hyunsoo Kim, Yun Suk Eo +6
A chiral superconductor has been proposed as one pathway to realize topological quantum computation utilizing the predicted Majorana normal fluid at its boundary (i.e., a point, ed…
Point Node Gap Structure of Spin-Triplet Superconductor UTe2
Tristin Metz, Seokjin Bae, Sheng Ran +7
Low-temperature electrical and thermal transport, magnetic penetration depth, and heat capacity measurements were performed on single crystals of the actinide superconductor UTe2 t…
Crystal structure of the unconventional spin-triplet superconductor UTe2 at low temperature by single crystal neutron diffraction
V. Hutanu, H. Deng, S. Ran +3
The crystal structure of the new superconductor UTe2 has been investigated for the first time at low temperature (LT) of 2.7 K, just closely above the superconducting transition te…
Extreme magnetic field-boosted superconductivity
Sheng Ran, I-Lin Liu, Yun Suk Eo +10
Applied magnetic fields underlie exotic quantum states, such as the fractional quantum Hall effect and Bose-Einstein condensation of spin excitations. Superconductivity, on the oth…
Intrinsic Low-Temperature Magnetism in SmB6
S. Gheidi, K. Akintola, A. M. Cote +6
By means of new muon spin relaxation experiments, we disentangle extrinsic and intrinsic sources of low-temperature bulk magnetism in the candidate topological Kondo insulator (TKI…
Magnetic impurities in Kondo insulators: An application to samarium hexaboride
W. T. Fuhrman, P. Nikolić
Impurities and defects in Kondo insulators can have an unusual impact on dynamics that blends with effects of intrinsic electron correlations. Such crystal imperfections are diffic…
Diamagnetic Sm in the topological Kondo insulator SmB
W. T. Fuhrman, J. C. Leiner, J. W. Freeland +5
Samarium hexaboride is a topological Kondo insulator, with metallic surface states manifesting from its insulating band structure. Since the insulating bulk itself is driven by str…
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…
Screened moments in a Kondo insulator
Wesley T. Fuhrman, Juan R. Chamorro, Pavel A. Alekseev +5
Long known to have thermodynamic properties at odds with its insulating electrical transport, SmB6 has been the subject of great debate as it is unclear whether its unusual propert…
