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…
Giant Domain Walls and Intrinsic Heterogeneity in 214 Cuprate Superconductors
Evie Ladbrook, Mark S. Senn, Jon Wright
The authors use scanning three‑dimensional X‑ray diffraction to map the bulk microstructure of the 1/8‑doped cuprate La₁.₆₇₅Eu₀.₂Sr₀.₁₂₅CuO₄, revealing broad tetragonal‑like domain…
Collective Magnetic Excitations in a Photo-excited Electron-doped Cuprate Superconductor
Daniel Jost, Jiarui Li, Jordyn Hales +21
The study uses time‑resolved resonant inelastic X‑ray scattering to monitor how collective magnetic excitations (paramagnons) in an optimally electron‑doped cuprate superconductor…
Magnetothermopower and particle-hole symmetry in a cuprate strange metal
Yu-Te Hsu, Matija Äulo, Thom Ottenbros +6
The authors measure magnetothermopower in overdoped Bi2201 cuprate crystals up to 35 T and find an extra field‑dependent contribution consistent with short‑range superconducting or…
Fractionalized Fermi liquids with the ghost-Gutzwiller Ansatz
Ivan Pasqua, Carlos Mejuto-Zaera, Michele Fabrizio
The paper demonstrates that a fractionalized Fermi liquid (FL*) phase can arise in the single‑band t‑J model using a simple ghost‑Gutzwiller variational Ansatz, producing a tempera…
