Gaps in unconventional superconductors
Andreas Kreisel
The paper reviews how the energy gap behaves in unconventional superconductors, explaining the non‑uniform gap structure, its origins, and how it appears in experimental measuremen…
Gap structure and phase diagram of twisted bilayer cuprates from a microscopic perspective
Siddhant Panda, Andreas Kreisel, Laura Fanfarillo +1
Since the prediction of a time-reversal symmetry breaking (TRSB) state in twisted bilayer cuprate superconductors by Can et al. [Nat.Phys. 17,519(2021)], several expe…
Inherent momentum-dependent gap structure of altermagnetic superconductors
Christian L. H. Rasmussen, Jannik Gondolf, Mats Barkman +4
Altermagnetic metals break time-reversal symmetry and feature spin-split Fermi surfaces generated by compensated Néel-ordered collinear magnetic moments. Being metallic, such alte…
Giant Rashba Splitting and Enhanced Nonlinear Berry-Phase Responses in Sliding-Tunable vdW MXene Heterostructures
Ali Sufyan, J. Andreas Larsson, Andreas Kreisel +1
Chalcogen-terminated van der Waals MXenes (M2CX2; M = Nb, Ta; X = S, Se) provide a robust platform for exploring strong spin-orbit coupling and proximity engineering. To probe thei…
Odd-Parity Magnetism in Fe-Based Superconductors
Reuel Dsouza, Andreas Kreisel, Brian M. Andersen +2
Odd-parity magnetism constitutes an intriguing phase of matter which breaks inversion symmetry while preserving time-reversal symmetry. Here we demonstrate that the Fe-based superc…
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…
