Spontaneous emergence of altermagnetism in the single-orbital extended Hubbard model
Jin-Wei Dong, Yu-Han Lin, Ruiqing Fu +4
Altermagnetism (AM), the recently discovered third class of collinear magnetic order, is characterized by non-relativistic momentum-dependent spin-split electronic structure with c…
Structural symmetry effects on the competition of density waves and superconductivity in bilayer nickelates
Steffen Bötzel, Aiman Al-Eryani, Jun Zhan +4
We investigate the interplay between spin-density-wave (SDW) order and superconductivity in the bilayer nickelate LaNiO using the functional renormalization group~(fRG)…
Magnetic configurations and excitations in high- multilayer nickelates
Jun Zhan, Xianxin Wu, Jiangping Hu
We investigate the magnetic ground states and transverse spin excitations of bilayer and trilayer nickelates within a multi-orbital itinerant framework. For the bilayer system, alt…
Pairing Mechanism in Bilayer Nickelate LaNiO Superconductors
Xianxin Wu, Tao Xiang, Jiangping Hu
The recent discovery of superconductivity with ~K in bilayer nickelate LaNiO provides a new setting in which to test the organizing principles of unconv…
Discovery of an odd-parity f-wave charge order in a kagome metal
Jiangchang Zheng, Caiyun Chen, Ruiqin Fu +13
The spontaneous breaking of symmetries is a cornerstone of physics, defining the phases of matter from the cosmological scale to the quantum realm. In condensed matter, electronic…
Raman response in superconducting multiorbital systems with application to nickelates
MatÃas Bejas, Jun Zhan, Xianxin Wu +2
The recent discovery of high- superconductivity in pressurized and thin film nickelates is nowadays one of the most relevant and active topics in solid-state physics. The orig…
