Giant Nernst effect in a Kondo lattice close to a quantum critical point
R. Bel, K. Behnia, Y. Nakajima +5
We present a study of Nernst and Seebeck coefficients of the heavy-fermion superconductor CeCoIn. Below 18 K, concomitant with a field-dependent Seebeck coefficient, a large…

Test of the Wiedemann-Franz law in an optimally-doped cuprate
Romain Bel, Kamran Behnia, Cyril Proust +3
We present a study of heat and charge transport in BiSrCuO focused on the size of the low-temperature linear term of the thermal conductivity at optimal dop…

Ambipolar Nernst effect in NbSe
Romain Bel, Kamran Behnia, Helmut Berger
The first study of Nernst effect in NbSe reveals a large quasi-particle contribution with a magnitude comparable and a sign opposite to the vortex signal. Comparing the effect…
