By patterning nanowires from the mixed valence compound YbAl3, we made the first measurements of quantum interference corrections (weak antilocalization, universal conductance fluctuations) of emergent heavy fermion quasiparticles. This work was reported as a letter in Phys. Rev. B.
The spin Seebeck effect in films of the antiferromagnetic insulating phase of V2O3 was found to have a thickness dependence, implying that the thermal relaxation length scale between spin waves and the lattice in this material is less than 50 nm. This work, led by Renjie Luo, was published in Phys. Rev. B.
Shot noise measurements in nanowires made from YbRh2Si2, a non-Fermi liquid "strange metal", show noise that is suppressed relative to what is seen in a nanowire made from a conventional metal like Au. This implies that the current may not be carried by well-defined quasiparticles in this system. This work, led by Liyang Chen, was reported in Science, and was the subject of a nice write-up in Quanta .
