Quetzalcoatlite as a Disorder-Free Platform for Chiral Magnetism and Frustration
Aleksandar Razpopov, P. Peter Stavropoulos, Michael R. Norman +1
The natural mineral quetzalcoatlite ZnCu(TeO)(OH) (AgPbCl) is a structurally ideal kagome magnet, providing a platform for exploring th…
Altermagnetism from a Cu-Fe Lieb Lattice in FeSe/Cuprate Heterostructures
Ying Li, Augustin Davignon, Peng Rao +4
The paper proposes that FeSe/cuprate heterostructures with a twisted Cu-Fe arrangement can host altermagnetism, producing spin‑split electronic bands without net magnetization, and…
Ab Initio Investigation of Pressure Effects in the Spin-Liquid Candidate Y-Kapellasite
Federico Abbruciati, Aleksandar Razpopov, Joao Elias F. S. Rodrigues +5
Motivated by recent experiments showing pressure-induced suppression of magnetic order and the emergence of a dynamical ground state in the anisotropic kagome antiferromagnet Y-kap…
Bobkingite, a new coupled sawtooth chain platform
P. Peter Stavropoulos, Aleksandar Razpopov, Harrison LaBollita +3
We investigate the mineral bobkingite, \ce{Cu5(OH)8Cl2(H2O)2}, as a potential realization of the sawtooth chain. Using \textit{ab initio} methods, we estimate the magnetic exchange…
Exact downfolding and its perturbative approximation
Jonas B. Profe, JakÅ¡a VuÄiÄeviÄ, P. Peter Stavropoulos +3
Solving the many-electron problem, even approximately, is one of the most challenging and simultaneously most important problems in contemporary condensed matter physics with vario…
Exploring d-Wave Magnetism in Cuprates from Oxygen Moments
Ying Li, Valentin Leeb, Krzysztof Wohlfeld +2
The antiferromagnetic parent phase of high-T cuprates has been established as a Néel state of copper moments, but early work pointed out the important role of ligand oxygen or…
