Direct High-Magnetic-Field Coupling to Stripe Order in a Cuprate Superconductor
Leonardo Martinelli, Izabela Biało, 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. Kràl, 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…
Orbital Separation of Charge Order and Superconductivity in LaSrCuO
I. Biało, 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…
Impact of Electron Correlations on Infinite-Layer Cuprates and Nickelates
Xunyang Hong, Yuetong Wu, Ying Chan +18
Optimization of unconventional superconductivity involves a balance of interaction strengths. Precise determination of correlation strength across different material families is th…
Differentiation of Site-Specific Symmetry Breaking Orders in YPrBaCuO
L. Martinelli, S. Rüdiger, I. Bialo +6
Solid matter is classified through symmetry of ordering phenomena. Experimentally, this approach is straightforward, except when distinct orderings occur with identical or almost i…

P. Kràl, J. N. Graham, V. Sazgari +21
The identification of high-temperature unconventional charge order and superconductivity in kagome quantum materials is pivotal for deepening our understanding of geometrically fru…
Magnetic Excitations of a Half-Filled Tl-based Cuprate
I. Biało, 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…
Unveiling the nature of collective charge excitations in a cuprate superconductor
Xunyang Hong, Yujie Yan, Leonardo Martinelli +33
Emergent symmetry breakings in condensed matter systems are often intimately linked to collective excitations. For example, the intertwined spin-charge stripe order in cuprate supe…
Decoupling of Static and Dynamic Charge Correlations revealed by Uniaxial Strain in a Cuprate Superconductor
L. Martinelli, I. Biało, X. Hong +17
We use uniaxial strain in combination with ultra-high-resolution Resonant Inelastic X-ray Scattering (RIXS) at the oxygen K- and copper L3-edges to study the excitations stemming f…
Discovery of Giant Unit-Cell Super-Structure in the Infinite-Layer Nickelate PrNiO
J. Oppliger, J. Küspert, A. -C. Dippel +10
Spectacular quantum phenomena such as superconductivity often emerge in flat-band systems where Coulomb interactions overpower electron kinetics. Engineering strategies for flat-ba…

K. von Arx, P. Rothenbühler, Qisi Wang +10
Multi-band Mott insulators with moderate spin-orbit and Hund's coupling are key reference points for theoretical concept developments of correlated electron systems. The ruthenate…
Engineering Phase Competition Between Stripe Order and Superconductivity in LaSrCuO
J. Küspert, I. Biało, R. Frison +18
Unconventional superconductivity often couples to other electronic orders in a cooperative or competing fashion. Identifying external stimuli that tune between these two limits is…
