摘要:

通过对非对称超导环上直流电压的观测,证明了环中的一个环段是直流电源。持续电流逆着该段中的总电场流动。当环或环段在非平衡噪声的作用下在超导态和正常态之间切换时,观察到了这种反常现象。我们证明了直流电压和功率的增加与相同的环串联连接的数量。在具有足够大数量的环的系统中可以获得足够用于实际应用的大电压和功率。我们指出,使用这样的系统的直流电压以上超导过渡和正常金属制成的不对称环的观察的可能性。

英文摘要:

The observations the dc voltage on asymmetric superconducting ring testify that one of the ring segments is a dc power source. The persistent current flows against the total electric field in this segment. This paradoxical phenomenon is observed when the ring or its segments are switched between superconducting and normal state by non-equilibrium noises. We demonstrate that the dc voltage and the power increase with the number of the identical rings connected in series. Large voltage and power sufficient for practical application can be obtained in a system with a sufficiently large number of the rings. We point to the possibility of using such a system for the observation of the dc voltage above superconducting transition and in the asymmetric rings made of normal metal.
