Altermagnets Enable Gate-Switchable Helical and Chiral Topological Transport with Spin-Valley-Momentum-Locked Dual Protection
Xianzhang Chen, Jiayong Zhang, Bowen Hao +5
We establish a unified, symmetry-driven framework that combines the alternating spin splitting of altermagnets with valley topology to realize and electrically interconvert helical…

Microwave Andreev bound state spectroscopy in a semiconductor-based Planar Josephson junction
Bassel Heiba Elfeky, Krishna Dindial, David S. Brandão +13
By coupling a semiconductor-based planar Josephson junction to a superconducting resonator, we investigate the Andreev bound states in the junction using dispersive readout techniq…
