超导性、超流性和零点振荡
Superconductivity, superfluidity and zero-point oscillations
摘要:
目前人们认为,为了解释超导现象,有必要了解电子对形成的机制。然而,成对的电子不能形成超导凝聚体。它们进行无序的零点振荡,在它们的系综中没有吸引力。为了创造一个统一的粒子系综,粒子对必须对它们的零点涨落进行排序,这样粒子之间就会出现吸引力。因此,电子气中零点振荡的有序性是超导性的原因,而表征这种有序性的参数决定了超导体的性质。零点振荡的凝聚模型创造了获得基本超导体的临界参数的估计的可能性,这也是在令人满意的协议与测量数据。另一方面,He-4和He-3的超流现象也可以用零点涨落的有序性来解释。因此,可以确定,这两种相关的现象是基于相同的物理机制。
英文摘要:
Currently it is thought that in order to explain the phenomenon of superconductivity is necessary to understand the mechanism of formation of electron pairs. However, the paired electrons cannot form a superconducting condensate. They perform disorderly zero-point oscillations and there are no attractive forces in their ensemble. To create a unified ensemble of particles, the pairs must order their zero-point fluctuations so that an attraction between the particles appears. For this reason, the ordering of zero-point oscillations in the electron gas is the cause of superconductivity and the parameters characterizing this order determine the properties of superconductors. The model of condensation of zero-point oscillations creates the possibility to obtain estimates for the critical parameters of elementary superconductors, which are also in the satisfactory agreement with measured data. On the another hand, the phenomenon of superfluidity in He-4 and He-3 can be similarly explained due to the ordering of zero-point fluctuations. Thus it is established that the both related phenomena are based on the same physical mechanism.
