Unidirectional Kondo scattering in layered NbS2
Edoardo Martino, Carsten Putzke, Markus König +13
Crystalline defects can modify quantum interactions in solids, causing unintuitive, even favourable, properties such as quantum Hall effect or superconducting vortex pinning. Here…
Origin of the 30 T transition in CeRhIn in tilted magnetic fields
S. Mishra, D. Gorbunov, D. J. Campbell +9
We present a comprehensive ultrasound study of the prototypical heavy-fermion material CeRhIn, examining the origin of the enigmatic 30 T transition. For a field applied at 2$^…
Wide critical fluctuations of the field-induced phase transition in graphite
Christophe Marcenat, Thierry Klein, David LeBoeuf +8
In the immediate vicinity of the critical temperature (T) of a phase transition, there are fluctuations of the order parameter, which reside beyond the mean-field approximation…
Thermodynamic signatures of the field-induced states of graphite
D. LeBoeuf, C. W. Rischau, G. Seyfarth +7
When a magnetic field confines the carriers of a Fermi sea to their lowest Landau level, electron-electron interactions are expected to play a significant role in determining the e…
ARPES view of orbitally resolved quasiparticle lifetimes in iron pnictides
Veronique Brouet, David LeBoeuf, Ping-Hui Lin +6
We study with ARPES the renormalization and quasiparticle lifetimes of the and / orbitals in two iron pnictides, LiFeAs and Ba(FeCo)A…
Two phase transitions induced by a magnetic field in graphite
Benoît Fauqué, David LeBoeuf, Baptiste Vignolle +3
Different instabilities have been speculated for a three-dimensional electron gas confined to its lowest Landau level. The phase transition induced in graphite by a strong magnetic…
