Robust semi-Dirac points and unconventional topological phase transitions in doped superconducting Sr2IrO4 tunnel coupled to t2g electron systems
Mats Horsdal, Timo Hyart
Semi-Dirac fermions are known to exist at the critical points of topological phase transitions requiring fine-tuning of the parameters. We show that robust semi-Dirac points can ap…
Enhancing triplet superconductivity by the proximity to a singlet superconductor in oxide heterostructures
Mats Horsdal, Giniyat Khaliullin, Timo Hyart +1
We show how in principle a coherent coupling between two superconductors of opposite parity can be realized in a three-layer oxide heterostructure. Due to strong intraionic spin-or…
Proposed Detection of the Topological Phase in Ring-Shaped Semiconductor-Superconductor Nanowires Using Coulomb Blockade Transport
Björn Zocher, Mats Horsdal, Bernd Rosenow
In semiconductor-superconductor hybrid structures a topological phase transition is expected as a function of chemical potential or magnetic field strength. We show that signatures…
Charge Fractionalization on Quantum Hall Edges
Mats Horsdal, Marianne Rypestøl, Hans Hansson +1
We discuss the propagation and fractionalization of localized charges on the edges of quantum Hall bars of variable widths, where interactions between the edges give rise to Luttin…
Photonic Josephson effect, phase transitions, and chaos in optomechanical systems
Jonas Larson, Mats Horsdal
A photonic analog of the Josephson effect is analyzed for a system formed by a partly transparent mechanical membrane dividing an optical cavity into two halves. Photons tunneling…
Are there sharp fractional charges in Luttinger liquids?
Jon Magne Leinaas, Mats Horsdal, T. H. Hansson
We examine charge fractionalization by chiral separation in a one-dimensional fermion system described by Luttinger liquid theory. The focus is on the question of whether the fract…
