非平衡弱场致磁：磁生物学的一种机制
Non-equilibrium, weak-field induced magnetism: a mechanism for magnetobiology
摘要：
长期以来，人们一直在探索弱磁场与生物物质相互作用的物理机制。有两个因素阻碍了这种机制的发展：第一，细胞环境的高（室温）温度，其中弱的静态磁场诱导（经典的）零平衡响应。其次，细胞环境中的摩擦力很大，阻止了弱场改变非平衡过程，如电荷的自由扩散。在这里，我们研究了一类非平衡稳态的细胞离子在一个封闭的潜力，其中的响应（弱，均匀，静态）磁场生存强摩擦和热波动。磁场引起离子以回旋频率进行的旋转运动。这种非平衡态是由作用于离子的白噪声产生的，而非局部（含记忆）摩擦和噪声是由平衡热浴产生的。该白噪声的强度可以是弱的，即比热噪声强度小得多。
英文摘要：
There is a long-time quest for understanding physical mechanisms of weak magnetic field interaction with biological matter. Two factors impeded the development of such mechanisms: first, a high (room) temperature of a cellular environment, where a weak, static magnetic field induces a (classically) zero equilibrium response. Second, the friction in the cellular environment is large, preventing a weak field to alter non-equilibrium processes such as a free diffusion of charges. Here we study a class of non-equilibrium steady states of a cellular ion in a confining potential, where the response to a (weak, homogeneous, static) magnetic field survives strong friction and thermal fluctuations. The magnetic field induces a rotational motion of the ion that proceeds with the cyclotron frequency. Such non-equilibrium states are generated by a white noise acting on the ion additionally to the non-local (memory-containing) friction and noise generated by an equilibrium thermal bath. The intensity of this white noise can be weak, i.e. much smaller than the thermal noise intensity.
