Bond-Length-Driven Magnetic Transition in Quasi-One-Dimensional CrSb (=S, Se)
Kang Lee, Hong-Suk Choi, K. -W. Lee
The authors use ab initio calculations to show that the magnetic order in quasi‑one‑dimensional CrSbX₃ (X = S, Se) is controlled by the Cr–Cr bond length, with a transition from an…

Altermagnetism and Weak Magnetism in the Insulating Distorted Perovskite Antiferromagnet NaOsO
Hong-Suk Choi, M. -C. Jung, K. -H. Ahn +2
The GdFeO-type perovskite antiferromagnet NaOsO, calculated here to be altermagnetic for all three typical collinear antiferromagnetic orders, was suggested early on to be…

External field induced metal-to-insulator transition in dissipative Hubbard model
Beomjoon Goh, Junwon Kim, Hongchul Choi +1
In this work, we develop a non-equilibrium steady-state non-crossing approximation (NESS-NCA) impurity solver applicable to general impurity problems. The choice of the NCA as the…
