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…
Non-Hermitian Many-Body Localization
Ryusuke Hamazaki, Kohei Kawabata, Masahito Ueda
Many-body localization is shown to suppress imaginary parts of complex eigenenergies for general non-Hermitian Hamiltonians having time-reversal symmetry. We demonstrate that a rea…
Operator Noncommutativity and Irreversibility in Quantum Chaos
Ryusuke Hamazaki, Kazuya Fujimoto, Masahito Ueda
We argue that two distinct probes of quantum chaos, i.e., the growth of noncommutativity of two unequal-time operators and the degree of irreversibility in a time-reversal test, ar…
