Optically Probing Tunable Band Topology in Atomic Monolayers
Gaofeng Xu, Tong Zhou, Benedikt Scharf +1
In many atomically thin materials their optical absorption is dominated by excitonic transitions. It was recently found that optical selection rules in these materials are influenc…
Crystalline Weyl semimetal phase in Quantum Spin Hall systems under magnetic fields
Fernando Dominguez, Benedikt Scharf, Ewelina M. Hankiewicz
We investigate an unconventional topological phase transition that occurs in quantum spin Hall (QSH) systems when applying an external in-plane magnetic field. We show that this tr…
Tuning Topological Superconductivity in Phase-Controlled Josephson Junctions with Rashba and Dresselhaus Spin-Orbit Coupling
Benedikt Scharf, Falko Pientka, Hechen Ren +2
Recently, topological superconductors based on Josephson junctions in two-dimensional electron gases with strong Rashba spin-orbit coupling have been proposed as attractive alterna…
Intervalley plasmons in crystals
Dinh Van Tuan, Benedikt Scharf, Igor Žutić +1
Collective charge excitations in solids have been the subject of intense research ever since the pioneering works of Bohm and Pines in the 1950s. Most of these studies focused on l…
