Correlation-driven tunability of altermagnetism in RuO
Ina Park, Dongwook Kim, Inho Lee +3
RuO has been regarded as a prototypical candidate for metallic altermagnet, offering a potential platform for high-speed and high-efficiency spintronics. However, the magnetic…

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…
