Momentum dependence of the superconducting gap in NdFeAsO0.9F0.1 single crystals measured by angle resolved photoemission spectroscopy.
We use angle resolved photoemission spectroscopy to study the momentum dependence of the superconducting gap in NdFeAsO0.9F0.1 single crystals. We find that the Gamma hole pocket is fully gappedExpand

Field-induced quantum critical point in CeCoIn5.
The resistivity of the heavy-fermion superconductor CeCoIn5 was measured as a function of temperature, down to 25 mK and in magnetic fields of up to 16 T applied perpendicular to the basal plane.Expand

Anisotropic Violation of the Wiedemann-Franz Law at a Quantum Critical Point
A quantum critical point transforms the behavior of electrons so strongly that new phases of matter can emerge. The interactions at play are known to fall outside the scope of the standard model ofExpand

Heat conduction in the vortex state of NbSe2: evidence for multiband superconductivity.
The thermal conductivity kappa of the layered s-wave superconductor NbSe2 was measured down to T(c)/100 throughout the vortex state. With increasing field, we identify two regimes: one with localizedExpand

Beyond triplet: Unconventional superconductivity in a spin-3/2 topological semimetal
Evidence of unconventional superconducting state in a topological semimetal confirms unprecedented spin-3/2 Cooper pairing. In all known fermionic superfluids, Cooper pairs are composed of spin-1/2Expand

Unpaired electrons in the heavy-fermion superconductor CeCoIn5.
Thermal conductivity and specific heat were measured in the superconducting state of the heavy-fermion material Ce(1-x)La(x)CoIn5. With increasing impurity concentration x, the suppression of T(c) isExpand

Heat transport as a probe of electron scattering by spin fluctuations: the case of antiferromagnetic CeRhIn(5).
Heat and charge conduction were measured in the heavy-fermion metal CeRhIn(5), an antiferromagnet with T(N)=3.8 K. The thermal resistivity is found to be proportional to the magnetic entropy,Expand
