超导体与重力

Superconductors and gravity

Antonio Gallerati, Giovanni Ummarino

摘要:

本文回顾和讨论了超导系统与局域引力场之间的非常规相互作用的最新进展。虽然我们知道引力扰动(如引力波)可以影响超凝聚和超流动力学,但在这里,我们想把重点放在作用于周围引力场的更微妙的超流反作用上,分析一些特定的有利情况。为此,我们将考虑适当的量子宏观系统在一个相干态,沉浸在静态弱地球的引力场,调查可能轻微的局部变化,后者没有解释的经典物理。

英文摘要:

We review and discuss some recent developments on the unconventional interaction between superconducting systems and the local gravitational field. While it is known that gravitational perturbations (such as gravitational waves) can affect supercondensates and supercurrents dynamics, here we want to focus on the more subtle superfluid back-reaction acting on the surrounding gravitational field, analysing some specific favourable situations. To this end, we will consider suitable quantum macrosystems in a coherent state, immersed in the static weak Earth's gravitational field, investigating possible slight local alterations of the latter not explained in terms of classical physics.
