Observation of an emergent energy scale close to dimensional reduction in a quasi-two-dimensional quantum magnet
Anneke Reinold, Laur Peedu, Kirill Amelin +19
By appropriately perturbing a critical transverse-field Ising chain away from its critical point, the system can develop a finite correlation length with a characteristic purely ma…
Observation of Macroscopic Nonlocal Voltage at Room Temperature
Jae Ho Jeon, Hong Ryeol Na, Sahng-Kyoon Jerng +13
Electrons in conductors suffer frequent scatterings with defects and phonons, and the diffusive macroscopic behaviors are determined by an external electric field through Ohms law.…
Unveiling Hidden Magnons with Anomalous Rotational Symmetry
Dirk Wulferding, Francesco Gabriele, Wojciech Brzezicki +7
Correlated materials with competing spin-orbit and crystal-field interactions can host composite spin-orbital magnons that are highly susceptible to structural and electronic pertu…
Spectroscopic Evidence of Competing Diagonal Spin Interactions and Spin Disproportionation in the Bilayer Nickelate LaNiO
Dong-Hyeon Gim, Dirk Wulferding, Hengyuan Zhang +2
A comprehensive spectroscopic map of the electronic, magnetic, and lattice excitations is presented for the bilayer nickelate LaNiO using Raman scattering at ambient pr…
Spinon excitations and spin correlations in the one-dimensional quantum magnet -VOSO probed by Raman spectroscopy
Dirk Wulferding, Diana Lucia Quintero-Castro, Pontus Laurell +3
Fractionalized excitations such as spinons and anyons have emerged as a central theme in condensed matter physics with broad implications for superconductivity, quantum statistics,…
Strain-induced Dynamic Spin-Phonon Coupling in Epitaxial RuO2 Films
In Hyeok Choi, Seung Gyo Jeong2, Jae Hyuck Lee +6
Magnetic order parameters in altermagnets can couple to quantized lattice vibration via both piezomagnetic and magnetoelastic effects, leading to the renormalization of phonon disp…
