英文摘要:
We investigate the large-fluctuation dynamics in financial markets, based on the minute-to-minute and daily data of the Chinese Indices and German DAX. The dynamic relaxation both before and after the large fluctuations is characterized by a power law, and the exponents $p_\\pm$ usually vary with the strength of the large fluctuations. The large-fluctuation dynamics is time-reversal symmetric at the time scale in minutes, while asymmetric at the daily time scale. Careful analysis reveals that the time-reversal asymmetry is mainly induced by external forces. It is also the external forces which drive the financial system to a non-stationary state. Different characteristics of the Chinese and German stock markets are uncovered.

中文摘要:
我们基于中国指数和德国DAX的逐分钟和每日数据,研究了金融市场的大波动动态。大涨落前后的动态弛豫以幂律为特征,指数$p_pm$通常随大涨落的强度而变化。大波动动力学在以分钟为单位的时间尺度上是时间反转对称的,而在日时间尺度上是不对称的。仔细分析表明,时间反转不对称性主要是由外力引起的。也是外部力量推动金融系统进入非平稳状态。揭示了中国和德国股市的不同特征。
