Point-gap topology of damped magnon excitations in skyrmion strings
Yusuke Koyama, Yuki Kawaguchi
We theoretically study the non-Hermitian topology of magnons with finite lifetimes due to Gilbert damping. By incorporating the spin-wave theory and perturbation theory for the Lan…

Universal Family-Vicsek scaling in quantum gases far from equilibrium
Kiryang Kwon, Kazuya Fujimoto, Junhyeok Hur +6
Fluctuations in the growing surfaces of classical systems can exhibit universal scaling behavior, known as Family-Vicsek (FV) scaling. Although this phenomenon was originally disco…
