Ultrasensitive strain modulation of terahertz magnons at a magnetic phase transition
Lichen Wang, Sajna Hameed, Yiran Liu +8
Antiferromagnets typically host spin-wave (magnon) excitations in the terahertz (THz) regime, offering a promising platform for high-speed magnonic information technologies. Harnes…
Comparative Raman study of Ruddlesden-Popper nickelates and the monolayer-trilayer polymorph
Vignesh Sundaramurthy, Abhi Suthar, Pascal Puphal +12
Ruddlesden-Popper (RP) nickelates have attracted intense interest following the discovery of superconductivity in several members of the series, including bilayer (BL) LaNi…
Hybridization of lattice and charge order excitations in a superconducting cuprate
S. M. Souliou, D. Ishikawa, R. Heid +9
The ubiquitous tendency of superconducting cuprates to form charge density waves (CDWs) has reignited interest in the nature of their electron-phonon interaction and its role in sh…
Uniaxial strain tuning of polar lattice vibrations in KTaO and SrTiO
I. Khayr, N. Somun, S. Hameed +11
The interplay of electronic and structural degrees of freedom is a prominent feature of many quantum materials and of particular interest in systems with strong ferroelectric fluct…
Evolution of spin excitations in superconducting LaCaCuO from the underdoped to the heavily overdoped regime
S. Hameed, Y. Liu, M. Knauft +8
We investigate high-energy spin excitations in hole-doped LaCaCuO films across a broad Ca doping range using resonant inelastic x-ray scatter…
Multiorbital character of the density wave in trilayer nickelate superconductors
A. Suthar, V. Sundaramurthy, M. Bejas +15
Ruddlesden-Popper nickelates exhibit high-temperature superconductivity closely intertwined with charge and spin density waves. However, fundamental questions persist regarding the…
