Cavity-mediated superconductor–ferromagnetic-insulator coupling
(Peer reviewed; Journal article, 2023)A recent proof of concept showed that cavity photons can mediate superconducting (SC) signatures to a ferromagnetic insulator (FI) over a macroscopic distance [A. T. G. Janssønn et al., Phys. Rev. B 102, 180506(R) (2020)]. ... -
Constrained s-wave weak-coupling superconductivity in multiband superconductors
(Peer reviewed; Journal article, 2023)We consider superconductivity in a system with N Fermi surfaces, including intraband and interband effective electron-electron interactions. The effective interaction is described by an N × N matrix whose elements are ... -
Enhancement of superconductivity mediated by antiferromagnetic squeezed magnons
(Journal article; Peer reviewed, 2019)We theoretically investigate magnon-mediated superconductivity in a heterostructure consisting of a normal metal and a two-sublattice antiferromagnetic insulator. The attractive electron-electron pairing interaction is ... -
Exceeding the Chandrasekhar-Clogston limit in flat-band superconductors: A multiband strong-coupling approach
(Peer reviewed; Journal article, 2023)Hybrid systems of superconductors and magnets display several intriguing properties, both from a fundamental physics point of view and with practical applications. Promising applications in superconducting spintronics ... -
Multiband strong-coupling superconductors with spontaneously broken time-reversal symmetry
(Peer reviewed; Journal article, 2023)We study superconducting three-band systems within strong-coupling Eliashberg theory. In particular, we search for phase-frustrated superconducting systems with spontaneous time-reversal symmetry breaking (TRSB) states. ... -
Zero temperature superconductor–edge metal–insulator transition in two-dimensional bosonic systems
(Peer reviewed; Journal article, 2022)Motivated by the recent experimental observation of an intermediate bosonic metallic state in the two-dimensional superconductor-insulator transition at T = 0 , we study an extended Bose-Hubbard model in the limit of a ...
