Field-tuned quasiparticles and electronic structure in heavy-fermion YbNi4P2

Will Broad, Owen Moulding, Takaki Muramatsu +7

We study the Fermi surface topology and quasiparticle properties in the heavy fermion compound YbNi4P2 at high magnetic fields using quantum oscillation measurements. We observe a…

Successive Electronic Topological Transitions in the Antiferromagnet UPd $_{2}$ Al $_{3}$

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 UPd $_{2}$ Al $_{3}$ inside the antiferro…

Interplay between Hund's rule and Kondo effect in a quantum dot

Olfa Dani, Johannes C. Bayer, Timo Wagner +2

The interaction between localized spins on a quantum dot and free electrons in the reservoirs forms a many-particle entangled system giving rise to the Kondo effect. Here, we inves…

Stabilization of U 5 $f^{2}$ configuration in UTe $_{2}$ through U 6d dimers in the presence of Te2 chains

Denise S. Christovam, Martin Sundermann, Andrea Marino +16

We investigate the topological superconductor candidate UTe $_{2}$ using high-resolution valence-band resonant inelastic x-ray scattering at the U $M_{4, 5}$ -edges. We observe atomic-l…
