DOI: 10.1088/1367-2630/ad762f
Abstract: Owing to the inherent characteristics of collective excitations in graphene, electrical control of edge plasmons is highly desirable for nanoplasmonic applications. This study investigates valley-polarized edge pseudomagnetoplasmons in a graphene p–n junction subjected to a… read more here.

DOI: 10.1103/physrevlett.130.156201
Abstract: Scattering processes in quantum materials emerge as resonances in electronic transport, including confined modes, Andreev states, and Yu-Shiba-Rusinov states. However, in most instances, these resonances are driven by a single scattering mechanism. Here, we show… read more here.
