828. Emergent multipole order of unconventional magnets

Focus session talk

A plethora of novel magnetic orders beyond the familiar ferromagnetism has recently been identified. These unusual orders arise typically from microscopic magnetic dipoles that are arranged in ways that do not result in a net magnetization. We present a systematic classification of macroscopic orders arising from microscopic-dipole configurations based on the recent standard-model description...

Focus session talk

We analyze the pairing instability of an altermagnetic metal on a square lattice driven by an attractive nearest-neighbor interaction. This interaction enables multiple pairing channels, including even-parity extended s-wave and d-wave states, as well as two odd-parity p-wave channels. We verify that altermagnetic spin-splitting in the single-particle dispersion gives rise to finite-momentum...

830. Collective modes of altermagnetic superconductors

AIP | Condensed Matter & Materials (CMM)

Focus session talk

We investigate collective modes in charge-neutral altermagnetic superconductors with d-wave spin-split bands, focusing on the impact of emergent Bogoliubov Fermi surfaces. In the absence of a magnetic field, the BCS state supports collective modes that inherit the underlying d-wave symmetry, resulting in pronounced momentum-space anisotropy. The broken time-reversal symmetry further couples...

90. Altermagnetism in Ultracold Quantum Gases

AIP | Condensed Matter & Materials (CMM)

Invited talk

Altermagnetism is an emerging form of compensated magnetism that combines vanishing net magnetization with momentum-dependent spin polarization and spin splitting. While most studies to date have focused on electronic materials, recent advances in ultracold atomic gases offer new opportunities to realize and investigate altermagnetic physics in highly controllable quantum many-body...
