Quadrupole spin polarization as signature of second-order topological superconductors
Kirill Plekhanov, Niclas Müller, Yanick Volpez +4
We study theoretically second-order topological superconductors characterized by the presence of pairs of zero-energy Majorana corner states. We uncover a quadrupole spin polarizat…
Time-Reversal Invariant Topological Superconductivity in Planar Josephson Bijunction
Yanick Volpez, Daniel Loss, Jelena Klinovaja
We consider a Josephson bijunction consisting of a thin -Josephson junction sandwiched between two-dimensional semiconducting layers with strong Rashba spin-orbit interact…
Second Order Topological Superconductivity in -Junction Rashba Layers
Yanick Volpez, Daniel Loss, Jelena Klinovaja
We consider a Josephson junction bilayer consisting of two tunnel-coupled two-dimensional electron gas layers with Rashba spin-orbit interaction, proximitized by a top and bottom $…
Rashba Sandwiches with Topological Superconducting Phases
Yanick Volpez, Daniel Loss, Jelena Klinovaja
We introduce a versatile heterostructure harboring various topological superconducting phases characterized by the presence of helical, chiral, or unidirectional edge states. Chang…
Three-Dimensional Fractional Topological Insulators in Coupled Rashba Layers
Yanick Volpez, Daniel Loss, Jelena Klinovaja
We propose a model of three-dimensional topological insulators consisting of weakly coupled electron- and hole-gas layers with Rashba spin-orbit interaction stacked along a given a…
Electronic instabilities of the extended Hubbard model on the honeycomb lattice from functional renormalization
Yanick Volpez, Daniel D. Scherer, Michael M. Scherer
Interacting fermions on the half-filled honeycomb lattice with short-range repulsions have been suggested to host a variety of interesting many-body ground states, e.g., a topologi…
