Hello,
Conductivity [itex]\sigma (\omega, k)[/itex] in Fourier space is defined by
[tex]
J(\omega, k)= \sigma (\omega, k) A(\omega, k)
[/tex]
In most cases the local limit of [itex] k\rightarrow 0 [/itex] is a good approximation particulalry in type I superconductors and HTC superconductors.
I am interested in cases where non-local electrodynamics [itex] k\neq 0 [/itex] is important. I would appreciate it if you could help me with
1-Can this nonlocality be observed?
2- Are there any applications based on this nonlocality?
3- Are you aware of any experiments or theoretical works that emphasises or uses this?
4-Anything related to the importance of nonlocal elecytrodynamics?
Thanks a lot in advance!
