-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…
Selective coupling of high-order phonons in La2-xSrxCuO4
Ke-Jun Xu, Paulina Majchrzak, Nathan Giles-Donovan +14
In crystals and molecules with strong coupling between the charge carriers and atomic vibrations, high order harmonics of the vibrational excitations can be observed with intensity…
-wave altermagnetism revealed by resonant inelastic X-ray scattering
Guangkai Zhang, Yuehong Li, Xubin Ye +16
Altermagnetism defines a third fundamental class of collinear magnetic order, featuring compensated magnetic moments with antiparallel spin alignment, yet lifted Kramers degeneracy…
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…
Strongly-coupled hybrid lattice-plasmons in layered cuprates
Ke-Jun Xu, Nathan Giles-Donovan, Stefano Agrestini +11
Metallic systems with delocalized valence electrons host collective charge density oscillations known as plasmons. On the other hand, conventional insulators do not have free elect…

The recent discovery of high-temperature superconductivity in hole-doped SmNiO, exhibiting the record-high transition temperature among infinite-layer (IL) nickelates, ha…
Unified Description of Charge Density Waves in Electron- and Hole-doped Cuprate Superconductors
Jaewon Choi, Sijia Tu, Abhishek Nag +7
High-temperature cuprates superconductors are characterised by the complex interplay between superconductivity (SC) and charge density wave (CDW) in the context of intertwined comp…
Impact of electron correlations on two-particle charge response in electron- and hole-doped cuprates
Abhishek Nag, Luciano Zinni, Jaewon Choi +13
Estimating many-body effects that deviate from an independent particle approach, has long been a key research interest in condensed matter physics. Layered cuprates are prototypica…

The striking discovery of high-temperature superconductivity (HTSC) of 80 K in a bilayer nickelate LaNiO under a moderately high pressure of about 14 GPa ignited a new…
Spin fluctuations sufficient to mediate superconductivity in nickelates
Paul Worm, Qisi Wang, Motoharu Kitatani +12
Infinite-layer nickelates show high-temperature superconductivity, and the experimental phase diagram agrees well with the one simulated within the dynamical vertex approximation (…
