Abstract

The turbulent thermal convection on the Sun is an example of an irreversible non-equilibrium phenomenon in a quasi-steady state characterized by a continuous entropy production rate. Here, the statistical features of a proxy of the local entropy production rate, in solar quiet regions at different timescales, are investigated and compared with the symmetry conjecture of the steady-state fluctuation theorem by Gallavotti and Cohen. Our results show that solar turbulent convection satisfies the symmetries predicted by the fluctuation relation of the Gallavotti and Cohen theorem at a local level.

摘要

太阳上的湍流热对流是一种准稳态不可逆非平衡现象的例子，其特征是具有连续的熵产生率。在此，研究了不同时间尺度下太阳宁静区域局部熵产生率代理的统计特征，并与加拉沃蒂和科恩提出的稳态涨落定理的对称性猜想进行了比较。我们的结果表明，太阳湍流对流在局部层面上满足加拉沃蒂和科恩定理涨落关系所预测的对称性。
