Coupling of Klein-Andreev Resonant States in BiSrCaCuO-graphene-BiSrCaCuO Devices
Sharadh Jois, Jose L. Lado, Genda Gu +2
Quantum devices require coherent coupling over macroscopic distances. Recently, resonances due to Klein tunneling and Andreev reflection states (KARS) have been observed in a natur…
Revealing Fano Resonance in Dirac Materials ZrTe5 through Raman Scattering
Di Cheng, Tao Jiang, Feng Zhang +10
We explore the Fano resonance in ZrTe5, using Raman scattering measurements. We identified two closely spaced B2g phonon modes, B2g I and B2g II, around 9 meV and 10 meV, respectiv…
Dynamical Generation of Higher-order Spin-Orbit Couplings, Topology and Persistent Spin Texture in Light-Irradiated Altermagnets
Sayed Ali Akbar Ghorashi, Qiang Li
Altermagnets have been identified as the third category of magnetic materials, exhibiting momentum-dependent spin splitting characterized by even powers of momentum. In this study,…
Unveiling Symmetry Instability induced by Topological Phase Transitions
Liang Luo, Boqun Song, Genda Gu +5
The symmetry-topology interplay dictates how to define order parameters and classify material ordered phases. However, current understanding of this interplay has been predominatel…
