Finite-temperature spin diffusion in the two-dimensional XY model
Erik Fitzner, Byungjin Lee, Junhyeok Hur +4
We present a combined theory-experiment study to quantify spin diffusion in the square lattice quantum spin-1/2 XY model at finite temperature. On the theory side, we leverage a re…
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…
Stability of many-body localization in two dimensions
Junhyeok Hur, Joey Li, Byungjin Lee +8
Disordered quantum many-body systems pose one of the central challenges in condensed matter physics and quantum information science, as their dynamics are generally intractable for…
Double-pass rotating z-cut quartz plate as a rapidly variable waveplate
Byungjin Lee, Kiryang Kwon, Jae-yoon Choi
We demonstrate a rapidly tunable waveplate based on a rotating z-cut quartz plate in a double-pass configuration. In contrast to previous single-pass implementations, where angular…
