Electrically Programmable Correlated Topology and Magnetism in a Moiré Trilayer
Christiano Wang Beach, Courtney Baier, Kaijie Yang +15
Strong electron-electron interactions underlie a wide range of quantum many-body phenomena, including magnetism, superconductivity, and charge fractionalization. A central goal is…
Distinct Suppression Mechanisms of Superconductivity by Magnetic Domains and Spin Fluctuations in EuFe2(As1-xPx)2 superconductors
Mengju Yuan, Nan Zhou, Ruixia Ti +10
Using ac composite magnetoelectric technique, we map the phase diagrams of EuFe(As1-xPx)2 to resolve the interplay between superconductivity and ferromagnetism. For samples with Tc…
Electron-magnon coupling at the interface of a "twin-twisted" antiferromagnet
Yue Sun, Fanhao Meng, Sijia Ke +9
We identify a "twin-twist" angle in orthorhombic two-dimensional magnets that maximizes interlayer orbital overlap and enables strong interfacial coupling. Focusing on the van der…
Goldstone mode of the broken helix in U(1) magnet EuIn2As2
Alex Liebman-Pelaez, Samuel J. Garratt, Veronika Sunko +5
Goldstone modes acquire a frequency gap in the presence of perturbations that break the underlying continuous symmetry. Here, we study the response of a spin-based Goldstone mode t…
