Nonlocal electrodynamics and the penetration depth of superconducting SrRuO
Henrik S. Røising, Andreas Kreisel, Brian M. Andersen
The thermal quasiparticles in a clean type-II superconductor with line nodes give rise to a quadratic low-temperature change of the penetration depth, , as first shown…
Thermodynamic transitions and topology of spin-triplet superconductivity: Application to UTe
Henrik S. Røising, Max Geier, Andreas Kreisel +1
The discovery of unconventional superconductivity in the heavy-fermion material UTe has reinvigorated research of spin-triplet superconductivity. We perform a theoretical study…
Superconductivity from Orbital-Selective Electron-Phonon Coupling in
Ethan T. Ritz, Henrik S. Røising, Morten H. Christensen +3
Recent experiments have shown that the phase diagrams of the kagome superconductors are strongly impacted by changes in the -axis lattice parameter.…
Ergodic Archimedean dimers
Henrik Schou Røising, Zhao Zhang
We study perfect matchings, or close-packed dimer coverings, of finite sections of the eleven Archimedean lattices and give a constructive proof showing that any two perfect matchi…
Searching For Dark Matter with Plasma Haloscopes
Alexander J. Millar, Steven M. Anlage, Rustam Balafendiev +24
We summarise the recent progress of the Axion Longitudinal Plasma HAloscope (ALPHA) Consortium, a new experimental collaboration to build a plasma haloscope to search for axions an…
Heat capacity double transitions in time-reversal symmetry broken superconductors
Henrik S. Røising, Glenn Wagner, Mercè Roig +2
Standard superconductors display a ubiquitous discontinuous jump in the electronic specific heat at the critical superconducting transition temperature. In a growing class of uncon…
The frustration-free fully packed loop model
Zhao Zhang, Henrik Schou Røising
We consider a quantum fully packed loop model on the square lattice with a frustration-free projector Hamiltonian and ring-exchange interactions acting on plaquettes. A boundary Ha…
The Superconductivity of SrRuO Under -Axis Uniaxial Stress
Fabian Jerzembeck, Henrik S. Røising, Alexander Steppke +7
Applying in-plane uniaxial pressure to strongly correlated low-dimensional systems has been shown to tune the electronic structure dramatically. For example, the unconventional sup…
Dark Sound
Alexander Balatsky, Benjo Fraser, Henrik Roising
We discuss the axion dark matter (DM) condensate and the consequences the interactions of dark matter would have on the spectrum of collective modes. We find that DM self-interacti…
Axion-matter coupling in multiferroics
Henrik S. Røising, Benjo Fraser, Sinéad M. Griffin +4
Multiferroics (MFs) are materials with two or more ferroic orders, like spontaneous ferroelectric and ferromagnetic polarizations. Such materials can exhibit a magnetoelectric effe…
A microscopic Ginzburg--Landau theory and singlet ordering in SrRuO
Glenn Wagner, Henrik S. Røising, Felix Flicker +1
The long-standing quest to determine the superconducting order of SrRuO (SRO) has received renewed attention after recent nuclear magnetic resonance (NMR) Knight shift expe…
Superconducting order of from a three-dimensional microscopic model
Henrik S. Røising, Thomas Scaffidi, Felix Flicker +2
We compute and compare even- and odd-parity superconducting order parameters of strontium ruthenate () in the limit of weak interactions, resulting fro…
Finite temperature effects on Majorana bound states in chiral -wave superconductors
Henrik Schou Røising, Roni Ilan, Tobias Meng +2
We study Majorana fermions bound to vortex cores in a chiral -wave superconductor at temperatures non-negligible compared to the superconducting gap. Thermal occupation of Carol…
Weak-coupling superconductivity in an anisotropic three-dimensional repulsive Hubbard model
Henrik Schou Røising, Felix Flicker, Thomas Scaffidi +1
We study a three-dimensional single-band repulsive Hubbard model at weak coupling. We establish the superconducting phase diagram in the parameter space of the chemical potential a…
Size Constraints on Majorana Beamsplitter Interferometer: Majorana Coupling and Surface-Bulk Scattering
Henrik Schou Røising, Steven H. Simon
Topological insulator surfaces in proximity to superconductors have been proposed as a way to produce Majorana fermions in condensed matter physics. One of the simplest proposed ex…
