Chiral-Angle-Controlled Altermagnetic Spin Splitting in Nanotubes

Ersoy Sasioglu, Tom. G. Saunderson, Börge Göbel +2

Altermagnets exhibit momentum-dependent spin splitting despite having zero net magnetization. Here, we show that rolling a two-dimensional (2D) $d$-wave altermagnet into a nanotube…
