Successive Electronic Topological Transitions in the Antiferromagnet UPdAl
Adrien Gourgout, Gaël Bastien, Dai Aoki +7
We report successive anomalies at low temperature in the magnetic field dependence of the thermoelectric signal in the heavy fermion compound UPdAl inside the antiferro…

Quantum critical origin of strange-metals at the end of a pseudogap phase in infinite-layer nickelates
C. Iorio-Duval, E. Beauchesne-Blanchet, F. Perreault +7
The quantum-critical origin of strange metals remains debated, particularly in cuprates where -linear resistivity emerges at the end of the pseudogap phase, a regime without lon…

Electronic thermal resistivity and quasi-particle collision cross-section in semi-metals
Adrien Gourgout, Arthur Marguerite, Benoît Fauqué +1
Electron-electron collisions lead to a T-square component in the electrical resistivity of Fermi liquids. The case of liquid He illustrates that the \textit{thermal} resitivity…
