Hydrodynamics of the viscous electron fluid in cadmium
Xiaodong Guo, Xiaokang Li, Benoît Fauqué +4
Thanks to electron-electron (-) collisions conserving momentum, metallic electron fluids are viscous. Yet, this viscosity is rarely detectable in bulk transport. Here, we rep…
Interaction driven transverse thermal resistivity in a phonon gas
Xiaodong Guo, Xiaokang Li, Alaska Subedi +2
The amplitude of the Hall response of electrons can be understood without invoking interactions. Most theories of the phonon thermal Hall effect have likewise opted for a non-inter…
Phonon Thermal Hall Effect in quartz and its absence in silica
Yu Ling, Benoît Fauqué, Benoît Fauqué +1
The observation of a misalignment between the applied heat flux and the measured temperature gradient in insulating solids induced by magnetic field has become a subject of experim…
T-square electric resistivity and its thermal counterpart in RuO
Yu Ling, Florent Pawula, Ramzy Daou +2
We present a study of low-temperature electric and thermal transport in RuO, a metallic oxide which has attracted much recent attention. Careful scrutiny of electric resistivit…
Electron-electron and electron-phonon collision cross sections in CsV3Sb5
Charles Menil, Andrea Capa Salinas, Stephen D. Wilson +2
AV3Sb5 (A=K, Rb, Cs) are kagome metals and superconductors, attracting much recent attention as nexus of multiple quantum states. Here, through a systematic study of electric and t…
Thermal Hall conductivity of semimetallic graphite dominated by ambipolar phonon drag
Qiaochao Xiang, Xiaokang Li, Xiaodong Guo +2
It is now known that in addition to electrons, other quasi-particles such as phonons and magnons can also generate a thermal Hall signal. Graphite is a semimetal with extremely mob…
