Observation of emergent scaling of spin-charge correlations at the onset of the pseudogap
Thomas Chalopin, Petar Bojović, Si Wang +12
In strongly correlated materials, interacting electrons are entangled and form collective quantum states, resulting in rich low-temperature phase diagrams. Notable examples include…
Theory of intervalley-coherent AFM order and topological superconductivity in tWSe
Ammon Fischer, Lennart Klebl, Valentin Crépel +7
The recent observation of superconductivity in the vicinity of Fermi surface reconstructed insulating or metallic states has established twisted bilayers of WSe\textsubscript{2} as…
Nonthermal order by disorder
Francesco Grandi, Antonio Picano, Ronny Thomale +2
The quench dynamics of systems exhibiting cooperative or almost competitive orders in equilibrium are explored using Ginzburg-Landau theory plus fluctuations. We show that when the…
Nature of metallic and insulating domains in the CDW system 1T-TaSe2
M. Straub, F. Petocchi, C. Witteveen +12
We study the electronic structure of bulk 1T-TaSe in the charge density wave phase at low temperature. Our spatially and angle resolved photoemission (ARPES) data show insulati…
Algorithm for computing perturbation series of dynamical mean field theory
Corentin Bertrand, Michel Ferrero, Olivier Parcollet
We show how to use diagrammatic techniques to compute the weak-coupling perturbation series of the self-consistent solution to a Dynamical Mean Field Theory (DMFT) problem. This ap…
High-field ultrasound study of elastic constants and possible magnetic symmetry transformations in UO2
E. A. Tereshina-Chitrova, L. V. Pourovskii, S. Khmelevskyi +2
In this study, we probe the coupling between magnetism and lattice dynamics in UO2, a 3k antiferromagnet that undergoes magnetic ordering below its Neel temperature (TN) of 30.8 K.…
