Two routes to quantum anomalous Hall states in altermagnets
Makoto Naka, Shuntaro Sumita, Yukitoshi Motome +1
We theoretically propose two possible routes to realizing quantum anomalous Hall states in altermagnetic materials. We consider a minimal square-lattice Hubbard model with antisymm…
Quantum Mechanism of Piezomagnetism in Higher-Spin Altermagnets
Daisuke Yamamoto, Makoto Naka
We investigate piezomagnetism in higher-spin altermagnets with easy-plane single-ion anisotropy using a flavor-wave approach. We show that quantum fluctuations of higher-spin colle…
Phase-modulated superconductivity via altermagnetism
Shuntaro Sumita, Makoto Naka, Hitoshi Seo
Stimulated by recent interest in altermagnets, a novel class of antiferromagnets with macroscopic time-reversal symmetry breaking, we investigate the coexistence of altermagnetism…
Nonrelativistic Piezomagnetic Effect in an Organic Altermagnet
Makoto Naka, Yukitoshi Motome, Tsuyoshi Miyazaki +1
We theoretically study the piezomagnetic effect on the altermagnetic state in -type molecular conductors, focusing on its nonrelativistic mechanism. By introducing shear stress…
Altermagnetic Perovskites
Makoto Naka, Yukitoshi Motome, Hitoshi Seo
Altermagnet is a class of antiferromagnets, which shows a staggered spin ordering with wave vector , while its net magnetization is canceled out in the limit of zero rel…
Spin-Orbital Ordering in Alkali Superoxides
Kohei Shibata, Makoto Naka, Harald O. Jeschke +1
Akali superoxides AO2 (A=Na, K, Rb, Cs), due to an open p shell of the oxygen ion O2^- with degenerate pi orbitals, have spin and orbital degrees of freedom. The complex magnetic,…
