Interfering trajectories in a ballistic Andreev cavity
Pankaj Mandal, Marcel Kaschper, Fernando Dominguez +9
The conventional description of transport through the interface between a normal conductor and a superconductor reduces the system to a one-dimensional problem treating Andreev ref…
Magnetic field-bias current interplay in HgTe-based three-terminal Josephson junctions
J. Thieme, W. Himmler, F. Dominguez +8
We investigate HgTe/Nb-based three-terminal Josephson junctions in T-shaped and X-shaped geometries and their critical current contours (CCCs). By decomposing the CCCs into the con…
Effects of spin-orbit coupling in a valley chiral kagomé network
P. Wittig, F. Dominguez, P. Recher
Valley chiral kagomé networks can arise in various situations, like for example, in double-aligned graphene-hexagonal boron nitride and periodically strained graphene. Here, we con…
Localized states coupled to a network of chiral modes in minimally twisted bilayer graphene
P. Wittig, F. Dominguez, C. De Beule +1
Minimally twisted bilayer graphene in the presence of an interlayer bias develops a triangular network of valley chiral modes that propagate along the interfaces and scatte…
Fraunhofer pattern in the presence of Majorana zero modes
F. Dominguez, E. G. Novik, P. Recher
We propose a new platform to detect signatures of the presence of Majorana bound states (MBSs) in the Fraunhofer pattern of Josephson junctions featuring quantum spin Hall edge sta…
Lifting topological protection in a quantum spin Hall insulator by edge coupling
Raul Stühler, André Kowalewski, Felix Reis +7
The scientific interest in two-dimensional topological insulators (2D TIs) is currently shifting from a more fundamental perspective to the exploration and design of novel function…
Network model and four-terminal transport in minimally twisted bilayer graphene
Christophe De Beule, Fernando Dominguez, Patrik Recher
We construct a two-channel scattering model for the triangular network of valley Hall states in interlayer-biased minimally twisted bilayer graphene from symmetry arguments and inv…
Effective Floquet model for minimally twisted bilayer graphene
Christophe De Beule, Fernando Dominguez, Patrik Recher
We construct an effective Floquet lattice model for the triangular network that emerges in interlayer-biased minimally twisted bilayer graphene and which supports two chiral channe…
Aharonov-Bohm Oscillations in Minimally Twisted Bilayer Graphene
C. De Beule, F. Dominguez, P. Recher
We investigate transport in the network of valley Hall states that emerges in minimally twisted bilayer graphene under interlayer bias. To this aim, we construct a scattering theor…
Chiral zigzag modes and flatbands in network models of twisted bilayer graphene
C. De Beule, F. Dominguez, P. Recher
We construct a phenomenological scattering theory for the triangular network of valley Hall states that arises in twisted bilayer graphene under interlayer bias. Crucially, our net…
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…
Testing Topological Protection of Edge States in Hexagonal Quantum Spin Hall Candidate Materials
Fernando Dominguez, Benedikt Scharf, Gang Li +5
We analyze the detailed structure of topological edge mode protection occuring in hexagonal quantum spin Hall (QSH) materials. We focus on bismuthene, antimonene, and arsenene on a…
Zero-energy pinning from interactions in Majorana nanowires
Fernando Domínguez, Jorge Cayao, Pablo San-Jose +3
Majorana zero modes at the boundaries of topological superconductors are charge-neutral, an equal superposition of electrons and holes. This ideal situation is, however, hard to ac…
Magnetic field tuning and quantum interference in a Cooper pair splitter
G. Fülöp, F. Domínguez, S. d'Hollosy +8
Cooper pair splitting (CPS) is a process in which the electrons of naturally occurring spin-singlet pairs in a superconductor are spatially separated using two quantum dots. Here w…
