Momentum Structure of Superconductivity and Sublattice Effects from Quasiparticle Interference in CsVSb
Aaron G. Greenberg, Xinze Yang, Junze Deng +11
The paper uses sub‑Kelvin scanning tunneling microscopy and quasiparticle interference analysis to map the superconducting gap of the kagome metal CsV₃Sb₅, finding an isotropic gap…
Organizing Principles for Moiré Quantum Matter
Qiaoling Xu, Yifan Gao, Tao Zhang +16
Moiré flat bands in van der Waals bilayers are usually discussed through a small set of mechanisms associated with the and valleys of hexagonal crystals, and more recentl…
Quantum geometry and critical temperature enhancement in MgB superconductivity
Yi Jiang, Haoyu Hu, Dumitru CÄlugÄru +13
MgB, a phonon-mediated superconductor with record-high critical temperature K, is revisited to obtain a comprehensive theory of electrons, phonons, and their cou…
Residual orbital magnetization governs the anomalous Hall effect in altermagnets
Yufei Zhao, Yiyang Jiang, Kamal Das +2
In altermagnets that exhibit anomalous Hall effect, the small remanent magnetization exists but has been treated as too small to be relevant to the Hall response. In this work, we…
New Crystal Structures Hide in Plain Sight: A Stress Test for AI-Guided Materials Discovery
Xin Zhang, Scott B. Lee, Sudipta Chatterjee +14
New types of crystal structures are discovered only rarely, and the artificial intelligence (AI) models now reshaping materials discovery have so far produced new chemical composit…
Engineering topological flat bands in -valley moiré systems with Ising-type SOC: twisted 1T-ZrS and 1T-SnSe
Hanqi Pi, Yves H. Kwan, Haoyu Hu +8
Twisted moiré superlattices hosting topological flat bands provide a platform to explore the interplay between topology and correlations. Here we investigate topological band stru…
