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.…
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…
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 alter…
Correlation Enhanced Electron-Phonon Coupling in FeSe/SrTiO at a Magic Angle
Qiang Zou, Antik Sihi, Basu Dev Oli +5
While a predictive theory for unconventional superconductivity in Fe-based superconductors remains elusive, an extensively debated aspect is the interaction between phonons and str…
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 microscop…
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…
Quasi-symmetry Constrained Spin Ferromagnetism in Altermagnets
Mercè Roig, Yue Yu, Rune C. Ekman +3
Altermagnets break time-reversal symmetry and their spin-orbit coupling (SOC) allow for an anomalous Hall effect (AHE) that depends on the direction of the Néel ordering vector. Th…
Minimal Models for Altermagnetism
Mercè Roig, Andreas Kreisel, Yue Yu +2
Altermagnets feature vanishing net magnetization, like antiferromagnets, but exhibit time-reversal symmetry breaking and momentum-dependent spin-split band structures. Motivated by…
Altermagnetism from coincident Van Hove singularities: application to -Cl
Yue Yu, Han-Gyeol Suh, Mercè Roig +1
Realizing two-dimensional (2D) altermagnets is important for spintronics applications. Here we propose a microscopic template for stabilizing 2D altermagnetism through Van Hove sin…
