Disorder-enhanced effective masses and deviations from Matthiessen's rule in PdCoO thin films
David Barbalas, Anaëlle Legros, Gaurab Rimal +2
The observation of hydrodynamic transport in the metallic delafossite PdCoO has increased interest in this family of highly conductive oxides, but experimental studies so far h…
Observation of 4- and 6-magnon bound-states in the spin-anisotropic frustrated antiferromagnet FeI
Anaëlle Legros, Shang-Shun Zhang, Xiaojian Bai +6
Spin-waves e.g. magnons are the conventional elementary excitations of ordered magnets. However, other possibilities exist. For instance, magnon bound-states can arise due to attra…
Linear-in temperature resistivity from an isotropic Planckian scattering rate
G. Grissonnanche, Y. Fang, A. Legros +8
A variety of "strange metals" exhibit resistivity that decreases linearly with temperature as , in contrast with conventional metals where resistivity decreases as…
The Future of the Correlated Electron Problem
A. Alexandradinata, N. P. Armitage, Andrey Baydin +44
A central problem in modern condensed matter physics is the understanding of materials with strong electron correlations. Despite extensive work, the essential physics of many of t…
Thermal Hall conductivity in the cuprate Mott insulators NdCuO and SrCuOCl
Marie-Eve Boulanger, Gaël Grissonnanche, Sven Badoux +11
The heat carriers responsible for the unexpectedly large thermal Hall conductivity of the cuprate Mott insulator LaCuO were recently shown to be phonons. However, the mecha…
Fermi surface transformation at the pseudogap critical point of a cuprate superconductor
Yawen Fang, Gael Grissonnanche, Anaelle Legros +11
The nature of the pseudogap phase remains a major barrier to our understanding of cuprate high-temperature superconductivity. Whether or not this metallic phase is defined by any o…
Gapless ground state in the archetypal quantum kagome antiferromagnet ZnCu(OH)Cl
P. Khuntia, M. Velazquez, Q. Barthélemy +7
Spin liquids are exotic phases of quantum matter challenging Landau's paradigm of symmetry-breaking phase transitions. Despite strong exchange interactions, spins do not order or f…
