Direct High-Magnetic-Field Coupling to Stripe Order in a Cuprate Superconductor
Leonardo Martinelli, Izabela BiaÅo, Jens Oppliger +47
Superconductivity in cuprates emerges out of a complex normal state that hosts density waves, pseudogap physics, and strange metal properties. Here, we access this normal state by…
Autonomous Diffractometry Enabled by Visual Reinforcement Learning
J. Oppliger, M. Stifter, A. Rüegg +7
Automation underpins progress across scientific and industrial disciplines. Yet, automating tasks requiring interpretation of abstract visual information remain challenging. For ex…
Correlated charge order intertwined with time-reversal symmetry-breaking nodal superconductivity in the dual flat band kagome superconductor CeRuSi
O. Gerguri, P. Krà l, M. Spitaler +19
Kagome materials provide a powerful platform for exploring how flat electronic bands promote symmetry-breaking quantum states, yet studies have so far focused mainly on kagome-deri…
Suppression of Spectral Gap and Flat Bands on a Cuprate Superconductor Side-Surface
Gabriele Domaine, Mihir Date, Sydney K. Y. Dufresne +27
Side surfaces of cuprate superconductors are expected to display a suppressed -wave order parameter and zero-energy topological flat bands with a large density of states, making…
Magnetic Excitations of a Half-Filled Tl-based Cuprate
I. BiaÅo, Q. Wang, J. Küspert +21
Strong electron correlations drive Mott insulator transitions. Yet, there exists no framework to classify Mott insulators by their degree of correlation. Cuprate superconductors, w…
Orbital Separation of Charge Order and Superconductivity in LaSrCuO
I. BiaÅo, O. Gerguri, L. Martinelli +12
We report a combined x-ray absorption (XAS) and oxygen -edge resonant inelastic x-ray scattering (RIXS) study of charge order in underdoped LaSrCuO () u…
