What is kinetic capacitance in superconductors or in solid state in general?

Hi,

I would appreciate it if anyone could explain to me what "kinetic capacitance" is, particularly in the context of superconductors or solids.

I understand "kinetic inductance" which comes from the kinetic energy of the conducting electrons but can not make the analogy for capacitance.

Thank you!

try looking up 'quantum phase slip' but the math is not for the faint hearted

Thanks, Sambristol! In fact my question on "kinetic capacitance" comes from studying "quantum phase slip". I understand it as a combination of coefficients with the dimension of capacitance in the "effective action" introduced by Golubev and Zaikin; however, I was hoping to get some physical intuition too or at least know the literature it was introduced first.
