-wave altermagnetic order parameter in hematite
Tianren Wang, Yuehong Li, Yu Feng +11
Altermagnets combine the vanishing net magnetization of antiferromagnets with momentum-dependent spin splitting. Magnon band splitting provides a direct probe of altermagnetic orde…
Strain-tunable charge localization coupled to complex magnetic orders in EuAl
M. Baumgartner, Xunyang Hong, Tianren Wang +19
Charge localization is particularly interesting when coupled to antiferromagnetic spin structures. Coupled spin-charge orders are well established in elemental chromium and correla…
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…
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…
Persistent paramagnons in high-temperature infinite-layer nickelate superconductors
Yujie Yan, Ying Chan, Xunyang Hong +25
The recent discovery of high-temperature superconductivity in hole-doped SmNiO, exhibiting the record-high transition temperature among infinite-layer (IL) nickelates, ha…
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…
Enhanced Superconductivity and Mixed-dimensional Behaviour in Infinite-layer Samarium Nickelate Thin Films
Mingwei Yang, Heng Wang, Jiayin Tang +24
Rare-earth infinite-layer nickelates represent an emerging class of unconventional superconductors, with materials synthesis largely limited to early lanthanide compounds. Here, we…
Anatomy of anomalous Hall effect due to magnetic fluctuations
Ola Kenji Forslund, Xiaoxiong Liu, Soohyeon Shin +16
The anomalous Hall {\color{black} e}ffect (AHE) has emerged as a key indicator of time-reversal symmetry breaking (TRSB) and topological features in electronic band structures. Abs…
Probing enhanced superconductivity in van der Waals polytypes of VTaS
Wojciech R. Pudelko, Huanlong Liu, Francesco Petocchi +15
Layered transition metal dichalcogenides (TMDs) stabilize in multiple structural forms with profoundly distinct and exotic electronic phases. Interfacing different layer types is a…
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…
Two-Dimensional Phase-Fluctuating Superconductivity in Bulk-Crystalline NdOFBiS
C. S. Chen, J. Küspert, I. Biało +11
We present a combined growth and transport study of superconducting single-crystalline NdOFBiS. Evidence of two-dimensional superconductivity with significant p…
Resolving the Orbital Character of Low-energy Excitations in Mott Insulator with Intermediate Spin-orbit Coupling

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…
Magnon interactions in a moderately correlated Mott insulator
