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…
Dynamical Scaling of Surface Roughness and Entanglement Entropy in Disordered Fermion Models
Kazuya Fujimoto, Ryusuke Hamazaki, Yuki Kawaguchi
Localization is one of the most fundamental interference phenomena caused by randomness, and its universal aspects have been extensively explored from the perspective of one-parame…
PT-symmetric non-Hermitian quantum many-body system using ultracold atoms in an optical lattice with controlled dissipation
Yosuke Takasu, Tomoya Yagami, Yuto Ashida +3
We report our realization of a parity-time (PT) symmetric non-Hermitian many-body system using cold atoms with dissipation. After developing a theoretical framework on PT-symmetric…
Magnetic solitons in a spin-1 Bose-Einstein condensate
Xiao Chai, Di Lao, Kazuya Fujimoto +3
Vector solitons are a type of solitary, or non-spreading wavepacket occurring in a nonlinear medium comprised of multiple components. As such, a variety of synthetic systems can be…
Flemish Strings of Magnetic Solitons and a Non-Thermal Fixed Point in a One-Dimensional Antiferromagnetic Spin-1 Bose Gas
Kazuya Fujimoto, Ryusuke Hamazaki, Masahito Ueda
Thermalization in a quenched one-dimensional antiferromagnetic spin-1 Bose gas is shown to proceed via a non-thermal fixed point through annihilation of Flemish-string bound states…
