parafermionic hinge states in a three-dimensional array of coupled nanowires
Sarthak Girdhar, Viktoriia Pinchenkova, Even Thingstad +1
We construct a model of a three-dimensional helical second-order topological superconductor formed by an array of weakly coupled Rashba nanowires. We identify the parameter regime…
Robust Tripartite Entanglement Generation via Correlated Noise in Spin Qubits
Sander Driessen, Ji Zou, Even Thingstad +2
We investigate the generation of genuine tripartite entanglement in a triangular spin-qubit system due to spatially correlated noise. In particular, we demonstrate how the formatio…
Topological Interlayer Superconductivity in a van der Waals Heterostructure
Even Thingstad, Joel Hutchinson, Daniel Loss +1
We show that when a honeycomb antiferromagnetic insulator (AFMI) is sandwiched between two transition metal dichalcogenide (TMD) monolayers in a commensurate way, magnons in the AF…
Cavity-enhanced superconductivity via band engineering
Valerii K. Kozin, Even Thingstad, Daniel Loss +1
We consider a two-dimensional electron gas interacting with a quantized cavity mode. We find that the coupling between the electrons and the photons in the cavity enhances the supe…
Tunable Ultrafast Dynamics of Antiferromagnetic Vortices in Nanoscale Dots
Ji Zou, Even Thingstad, Se Kwon Kim +2
Topological vortex textures in magnetic disks have garnered great attention due to their interesting physics and diverse applications. However, up to now, the vortex state has main…
Strong-coupling approach to temperature dependence of competing orders of superconductivity: Possible time-reversal symmetry breaking and nontrivial topology
Chi Sun, Kristian Mæland, Even Thingstad +1
We use strong-coupling Eliashberg theory to study the competition of separate superconducting orders at low temperatures. Specifically, we study magnon-mediated superconductivity i…
Fractional Spin Quantum Hall Effect in Weakly Coupled Spin Chain Arrays
Even Thingstad, Pierre Fromholz, Flavio Ronetti +2
Topological magnetic insulators host chiral gapless edge modes. In the presence of strong interaction effects, the spin of these modes may fractionalize. Studying a 2D array of cou…
Dissipative Spin-wave Diode and Nonreciprocal Magnonic Amplifier
Ji Zou, Stefano Bosco, Even Thingstad +2
We propose an experimentally feasible dissipative spin-wave diode comprising two magnetic layers coupled via a non-magnetic spacer. We theoretically demonstrate that the spacer med…
One-Dimensional Spin-Polarised Surface States -- A Comparison of Bi(112) with Other Vicinal Bismuth Surfaces
Anna Cecilie Åsland, Johannes Bakkelund, Even Thingstad +8
Vicinal surfaces of bismuth are unique test-beds for investigating one-dimensional (1D) spin-polarised surface states that may one day be used in spintronic devices. In this work,…
Eliashberg study of superconductivity induced by interfacial coupling to antiferromagnets
Even Thingstad, Eirik Erlandsen, Asle Sudbø
We perform Eliashberg calculations for magnon-mediated superconductivity in a normal metal, where the electron-magnon interaction arises from interfacial coupling to antiferromagne…
Phonon-mediated superconductivity in doped monolayer materials
Even Thingstad, Akashdeep Kamra, Justin W. Wells +1
Insight into why superconductivity in pristine and doped monolayer graphene seems strongly suppressed has been central for the recent years' various creative approaches to realize…
Antiferromagnetic magnons as highly squeezed Fock states underlying quantum correlations
Akashdeep Kamra, Even Thingstad, Gianluca Rastelli +4
Employing the concept of two-mode squeezed states from quantum optics, we demonstrate a revealing physical picture for the antiferromagnetic ground state and excitations. Superimpo…
Chiral Phonon Transport Induced by Topological Magnons
Even Thingstad, Akashdeep Kamra, Arne Brataas +1
The plethora of recent discoveries in the field of topological electronic insulators has inspired a search for boson systems with similar properties. There are predictions that fer…
