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…
Superconductivity induced by altermagnetic spin fluctuations in high-pressure MnB
Danylo Radevych, Mercè Roig, Daniel F. Agterberg +1
Recent experiments found superconductivity in nonmagnetic MnB with a high critical temperature () reaching 14 K at 158 GPa. However, ab initio calculations of the electr…
Origin of sublattice particle-hole asymmetry in monolayer FeSe superconductors
Mercè Roig, Kazi Ranjibul Islam, Basu Dev Oli +7
In iron-based superconductors, the two Fe atoms in the unit cell are typically related by crystal symmetries; therefore, we expect no intra-unit cell variations in the superconduct…
Symmetry-required Orbital Selectivity in Monolayer FeSe
Mercè Roig, Qiang Zou, Basu Dev Oli +6
Orbital-selective correlations have been observed to play an important role in Fe-based superconductors. Here, in contrast to previous site-local Mott transition-based origins, we…
Odd-parity Magnetism Driven by Antiferromagnetic Exchange
Yue Yu, Magnus B. Lyngby, Tatsuya Shishidou +5
Realizing odd-parity, time-reversal-preserving, non-relativistic spin splitting is a central goal for spintronics applications. We propose a group-theory-based microscopic framewor…
Local signatures of altermagnetism
Jannik Gondolf, Andreas Kreisel, Mercè Roig +3
Altermagnets constitute a class of collinear compensated Néel ordered magnets that break time-reversal symmetry and feature spin-split band structures. Based on versatile microsco…
