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…
Pair-mixing induced Time-reversal-breaking superconductivity
Saswata Mandal, Chao-Xing Liu
Experimental evidences of spontaneous time-reversal (TR) symmetry breaking have been reported for the superconducting ground state in the transition metal dichalcogenide (TMD) supe…
A Topological Superconductor Tuned by Electronic Correlations
Haoran Lin, Christopher L. Jacobs, Chenhui Yan +15
A topological superconductor, characterized by either a chiral order parameter or a chiral topological surface state in proximity to bulk superconductivity, is foundational to topo…
Strong Inter-valley Electron-Phonon Coupling in Magic-Angle Twisted Bilayer Graphene
Cheng Chen, Kevin P. Nuckolls, Shuhan Ding +31
The unusual properties of superconductivity in magic-angle twisted bilayer graphene (MATBG) have sparked enormous research interest. However, despite the dedication of intensive ex…
