Spatially Inhomogeneous Superconducting and Bosonic Networks With Emergent Complex Behaviors
摘要:
增强响应和局部有序的自发出现通常与非线性和空间不均匀性占主导地位的复杂物质有关。我们讨论了超导约瑟夫森结网络和冷原子在光晶格中实现的量子器件中的这些现象。我们的证据如何有关工程网络的形状诱导超导阵列中的零电压约瑟夫森临界电流的增强,以及出现的空间局部冷凝冷原子在不均匀的光晶格。
英文摘要:
The spontaneous emergence of enhanced responses and local orders are properties often associated with complex matter where nonlinearities and spatial inhomogeneities dominate. We discuss these phenomena in quantum devices realized with superconducting Josephson junction networks and cold atoms in optical lattices. We evidence how the pertinent engineering of the network's shape induces the enhancement of the zero-voltage Josephson critical currents in superconducting arrays as well as the emergence of spatially localized condensates for cold atoms in inhomogeneous optical lattices.
