Coreless vortices as direct signature of chiral -wave superconductivity

P Holmvall, AM Black-Schaffer - Physical Review B, 2023 - APS
Chiral d-wave superconductivity has been proposed in a number of different materials, but
characteristic experimental fingerprints have been largely lacking. We show that quadruply …

Robust and tunable coreless vortices and fractional vortices in chiral -wave superconductors

P Holmvall, N Wall-Wennerdal, AM Black-Schaffer - Physical Review B, 2023 - APS
Chiral d-wave superconductivity has recently been proposed in a wide range of materials
based on both experiment and theoretical studies. Chiral superconductors host a finite …

Nematic skyrmions in odd-parity superconductors

AA Zyuzin, J Garaud, E Babaev - Physical review letters, 2017 - APS
We study topological excitations in two-component nematic superconductors, with a
particular focus on Cu x Bi 2 Se 3 as a candidate material. We find that the lowest-energy …

Phase diagram of superconductivity in the integer quantum Hall regime

J Schirmer, CX Liu, JK Jain - Proceedings of the National …, 2022 - National Acad Sciences
An interplay between pairing and topological orders has been predicted to give rise to
superconducting states supporting exotic emergent particles, such as Majorana particles …

Topological phase transitions in small mesoscopic chiral -wave superconductors

LF Zhang, L Covaci, MV Milošević - Physical Review B, 2017 - APS
Spin-triplet chiral p-wave superconductivity is typically described by a two-component order
parameter, and as such is prone to unique emergent effects when compared to the standard …

Skyrmionic chains and lattices in superconductors

LF Zhang, YY Zhang, GQ Zha, MV Milošević, SP Zhou - Physical Review B, 2020 - APS
We report characteristic vortex configurations in s+ id superconductors with time-reversal
symmetry breaking, exposed to magnetic field. A vortex in the s+ id state tends to have an …

Multichiral ground states in mesoscopic -wave superconductors

VF Becerra, MV Milošević - Physical Review B, 2016 - APS
Using Ginzburg-Landau formalism, we investigate the effect of confinement on the ground
state of mesoscopic chiral p-wave superconductors in the absence of magnetic field. We …

Vortical configurations in mesoscopic superconducting square loop with mixed pairing orders

GQ Zha - Europhysics Letters, 2020 - iopscience.iop.org
Based on the microscopic Bogoliubov-de Gennes theory, we study vortical configurations in
a mesoscopic superconducting square loop with mixed pairing orders. By choosing …
