Numerical Investigation of a Bifurcation Problem with free Boundaries Arising from the Physics of Josephson Junctions
M. D. Todorov, T. L. Boyadjiev
提出了一种计算“一维”约瑟夫森结最小长度的直接方法,其中磁通量的特定分布保持其稳定性。 由于结的长度是一个可变的数量,因此将相应的非线性光谱问题解释为自由边界的问题。 获得的结果给我们保修考虑为“长”,其中存在至少一个非平凡的稳定分布的磁通量固定值的所有其他参数。
A direct method for calculating the minimal length of "one-dimensional" Josephson junctions is proposed, in which the specific distribution of the magnetic flux retains its stability. Since the length of the junctions is a variable quantity, the corresponding nonlinear spectral problem as a problem with free boundaries is interpreted. The obtained results give us warranty to consider as "long", every Josephson junction in which there exists at least one nontrivial stable distribution of the magn...
