題名: | Nonequilibrium quench dynamics in quantum quasicrystals | 作者: | 林瑜琤 Iglói,Ferenc ; Roósz, Gergő ; Lin,Yu-Cheng |

In particular, we consider the dynamics of the entanglement entropy and the relaxation of the magnetization. The entanglement entropy increases with time as a power law, and the magnetization is found to exhibit stretched-exponential relaxation. These behaviors are explained in terms of anomalously diffusing quasiparticles, which are studied in a wave packet approach. The non-equilibrium magnetization is shown to have a dynamical phase transition. | 關聯: | New Journal of Physics, 15(2), 023036 | 資料類型: | article | DOI: | http://dx.doi.org/10.1088/1367-2630/15/2/023036 |
