Anomalously high quasiparticle thermal conductivity in the underdoped cuprate superconductor HgBaCuO

Jordan Baglo, Quentin Barthélemy, Étienne Lefrançois +4

The single-layer cuprate superconductor HgBaCuO (Hg1201) is an ideal candidate for investigating many properties of cuprates with minimal disorder and without the co…

Thermal Hall conductivity of electron-doped cuprates: Electrons and phonons

Marie-Eve Boulanger, Lu Chen, Vincent Oliviero +7

It has recently become clear that phonons generate a sizable thermal Hall effect in cuprates, whether they are undoped, electron-doped or hole-doped (inside the pseudogap phase). A…

Thermal Hall conductivity in the strongest cuprate superconductor: Estimate of the mean free path in the trilayer cuprate HgBaCaCuO

Munkhtuguldur Altangerel, Quentin Barthélemy, Étienne Lefrançois +12

The thermal Hall conductivity of the trilayer cuprate HgBaCaCuO (Hg1223) - the superconductor with the highest critical temperature at ambient pressure -…

Electronic mean free path of the cuprate superconductor BiSrCaCuO from thermal Hall conductivity

Emma Campillo, Manel Mezidi, Lu Chen +6

We use thermal transport to access the electronic mean free path of -wave quasiparticles in one of the most widely studied cuprate superconductors, BiSrCaCuO$_{8+δ}…

Role of magnetic ions in the thermal Hall effect of the paramagnetic insulator TmVO

Ashvini Vallipuram, Lu Chen, Emma Campillo +9

In a growing number of materials, phonons have been found to generate a thermal Hall effect, but the underlying mechanism remains unclear. Inspired by previous studies that reveale…
