Magnetic memory and distinct spin populations in ferromagnetic Co3Sn2S2
Charles Menil, Brigitte Leridon, Antonella Cavanna +7
Co3Sn2S2, a ferromagnetic Weyl semi-metal with Co atoms on a kagome lattice, has generated much recent attention. Experiments have identified a temperature scale below the Curie te…
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…
Tuning the BCS-BEC crossover of electron-hole pairing with pressure
Yuhao Ye, Jinhua Wang, Pan Nie +5
In graphite, a moderate magnetic field confines electrons and holes into their lowest Landau levels. In the extreme quantum limit, two insulating states with a dome-like field depe…
The polarisation fluctuation length scale shaping the superconducting dome of SrTiO
Benoît Fauqué, Shan Jiang, Tom Fennell +7
Superconducting domes, ubiquitous across a variety of quantum materials, are often understood as a window favorite for pairing opened by the fluctuations of competing orders. Yet,…
Phonon hydrodynamics in bulk insulators and semi-metals
Yo Machida, Valentina Martelli, Alexandre Jaoui +2
Decades ago, Gurzhi proposed that if momentum-conserving collisions prevail among heat-carrying phonons in insulators and charge-carrying electrons in metals, hydrodynamic features…
High-field immiscibility of electrons belonging to adjacent twinned bismuth crystals
Yuhao Ye, Akiyoshi Yamada, Yuto Kinoshita +16
Bulk bismuth has a complex Landau spectrum. The small effective masses and the large g-factors are anisotropic. The chemical potential drifts at high magnetic fields. Moreover, twi…
Glass-like thermal conductivity and narrow insulating gap of EuTiO
Alexandre Jaoui, Shan Jiang, Xiaokang Li +8
Crystals and glasses differ by the amplitude and the temperature dependence of their thermal conductivity. However, there are crystals known to display glass-like thermal conductiv…
An electronic band sculpted by oxygen vacancies and indispensable for dilute superconductivity
Benoît Fauqué, Clément Collignon, Hyeok Yoon +5
Dilute superconductivity survives in bulk strontium titanate when the Fermi temperature falls well below the Debye temperature. Here, we show that the onset of the superconducting…
Magnetic freeze-out and anomalous Hall effect in ZrTe
Adrien Gourgout, Maxime Leroux, Jean-Loup Smirr +10
The ultra-quantum limit is achieved when a magnetic field confines an electron gas in its lowest spin-polarised Landau level. Here we show that in this limit, electron doped ZrTe$_…
Mesoscopic tunneling in strontium titanate
Benoît Fauqué, Philippe Bourges, Alaska Subedi +6
Spatial correlation between atoms can generate a depletion in the energy dispersion of acoustic phonons. Two well known examples are rotons in superfluid helium and the Kohn anomal…
Magneto-Seebeck effect in bismuth
Felix Spathelf, Benoît Fauqué, Kamran Behnia
Thermoelectricity was discovered almost two centuries ago in bismuth. The large and negative Seebeck coefficient of this semimetal remains almost flat between 300 K and 100 K. This…
Phonon drag thermal Hall effect in metallic strontium titanate
Shan Jiang, Xiaokang Li, Benoît Fauqué +1
SrTiO, a quantum paralectric, displays a detectable phonon thermal Hall effect (THE). Here we show that the amplitude of THE is extremely sensitive to stoichiometry. It drastic…
Formation of an electron-phonon bi-fluid in bulk antimony
Alexandre Jaoui, Adrien Gourgout, Gabriel Seyfarth +4
The flow of charge and entropy in solids usually depends on collisions decaying quasiparticle momentum. Hydrodynamic corrections can emerge, however, if most collisions among quasi…
Boundary conductance in macroscopic bismuth crystals
Woun Kang, Felix Spathelf, Benoît Fauqué +2
The interface between a solid and vacuum can become electronically distinct from the bulk. This feature, encountered in the case of quantum Hall effect, has a manifestation in insu…
