Superconductivity from altermagnetic fluctuations: the crucial role of sublattice polarization
Mats Barkman, Andreas Kreisel, Brian M. Andersen
Unconventional superconductivity in correlated systems often appears in the vicinity of a magnetically ordered state. This situation is also relevant for altermagnets, characterize…
Odd-parity surface magnetism in a Kondo insulator
Maxim Dzero, Brian M. Andersen
We formulate a theory of spin-polarized tunneling between a nanowire tip of a topological Kondo insulator SmB and the bi-collinear antiferromagnet FeTe in which the tun…
Multi-orbital physics in inverse Lieb lattice altermagnets
Mercè Roig, Jannik Gondolf, Andreas Kreisel +2
The inverse Lieb lattice has recently emerged as a promising platform for altermagnetism, with several materials with this structure proposed as -wave altermagnetic candidates.…
Kohn-Luttinger Superconductivity of Weyl Fermi Arcs in PtBi
Reuel Dsouza, Nikolaos Parthenios, Brian M. Andersen +1
Recent experimental observations in the noncentrosymmetric Weyl semimetal PtBi indicate unconventional superconductivity hosted by topological surface states -- Weyl Fermi arcs…
Topological surface states revealed by the Zeeman effect in superconducting UTe2
Zhen Zhu, Hans Christiansen, Yudi Huang +11
Intrinsic topological superconductors with protected boundary modes obeying non-Abelian statistics constitute a vanishingly small class of quantum materials. A defining spectroscop…
Zero-field superconducting vortices and Majorana zero modes pinned by magnetic islands in correlated Rashba systems
Panagiotis Kotetes, Brian M. Andersen
We propose a route for pinning zero-field superconducting vortices in systems which are exchange-coupled to magnetic islands and feature Rashba spin-orbit coupling. We consider isl…
Fractional quantum vortices in chiral kagome superconductors
Frederik A. S. Philipsen, Mats Barkman, Andreas Kreisel +1
We perform a theoretical investigation of the nature of vortices in chiral superconductors on the kagome lattice. The study is motivated by recent experimental developments…
Protection of Unconventional Superconductivity from Disorder
Sofie Castro Holbæk, Morten H. Christensen, Andreas Kreisel +1
Unconventional superconductivity is a desirable state of matter due to its potential for high transition temperatures and associated favorable superconducting prop…
Visualizing the low-energy electronic structure of the triplet superconductor UTe through quasiparticle interference
Anuva Aishwarya, Hans Christiansen, Sheng Ran +6
The identification, control and theoretical modelling of spin-triplet superconductors (STC) remain a central theme in quantum materials research. Intrinsic STC are rare but offer r…
