Magnetic circular dichroism of THz modes and selection rules of Raman-active optical phonons in the polar altermagnet candidate \ce{Mn2Mo3O8}
F. Schilberth, K. Vasin, M. Knauft +14
We investigated the magnetic and vibrational excitations in the collinear altermagnet candidate \ce{Mn2Mo3O8} by temperature dependent Raman scattering and magneto-optical THz time…
Three-dimensional zigzag correlations in the van der Waals Kitaev magnet RuBr
H. Gretarsson, R. Iwazaki, F. Sato +8
Ruthenium trihalides Ru ( = Cl, Br, I) provide a tunable platform for Kitaev magnetism in two-dimensional van der Waals materials. Despite their similar crystal structures…
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…
Signatures of three-dimensional photo-induced superconductivity in YBaCuO
M. Rosenberg, D. Nicoletti, M. Buzzi +5
Optical excitation of large-amplitude apical oxygen phonon oscillations has been shown to renormalize the electronic properties of YBaCuO, inducing a superconductin…
Enhanced coherent terahertz emission from critical superconducting fluctuations in YBaCuO
D. Nicoletti, M. Rosenberg, M. Buzzi +10
Coherent terahertz (THz) emission is emerging as a powerful new tool to probe symmetry breakings in quantum materials. This method relies on second order optical nonlinearities and…
Enhanced coherence and layer-selective charge order in a trilayer cuprate superconductor
S. Smit, M. Bluschke, P. Moen +25
Trilayer cuprates hold the record for the highest superconducting critical temperatures (), yet the underlying mechanism remains elusive. Using time- and angle-resolv…
