论文摘要
在存在损失，当前偏见和热噪声源的情况下，通过非线性超透析效应在磁性驱动的长约瑟夫森连接中实现了传播正弦呼吸器的产生。我们演示了如何通过受控的磁性脉冲专门诱导呼吸模式。仅观察到仅呼吸器生成概率的非单调行为是噪声强度的函数。提出了一种提供约瑟夫森呼吸器存在证据的实验方案。
The generation of travelling sine-Gordon breathers is achieved through the nonlinear supratransmission effect in a magnetically driven long Josephson junction, in the presence of losses, a current bias, and a thermal noise source. We demonstrate how to exclusively induce breather modes by means of controlled magnetic pulses. A nonmonotonic behavior of the breather-only generation probability is observed as a function of the noise intensity. An experimental protocol providing evidence of the Josephson breather's existence is proposed.
