考虑场依赖扩散系数影响的熵驱动相变

Entropy-driven phase transitions with influence of the field-dependent diffusion coefficient

V. O. Kharchenko

摘要:

本文研究了具有低次幂形式迁移率和内部涨落的单场反应扩散随机系统的相变。利用变分原理和平均场论证明了噪声可以维持空间模式并导致无序的相变。我们已经表明,相变可以是临界或非临界的字符。

英文摘要:

We present a comprehensive study of the phase transitions in the single-field reaction-diffusion stochastic systems with field-dependent mobility of a power-low form and the internal fluctuations. Using variational principles and mean-field theory it was shown that the noise can sustain spatial patterns and leads to disordering phase transitions. We have shown that the phase transitions can be of critical or non-critical character.
