I cannot find any function to do this in Finite elements

How should I implement this in deal.II?

You mean that you want to *extend the solution from the neighboring cell to the current cell*? In general, the polynomials that describe the solution are of course only defined on one cell, and there is a separate polynomial description on the neighboring cell.
