While mostly used for plants, there's another method that's essentially shooting cells with bullets coated in genes

Perhaps the most brutal way of introducing nucleic acids into cells is microinjection: you make a really, really fine needle, jab it into a cell's nucleus, and inject a DNA solution. It is incredibly painstaking work, does kill a lot of the cells, and making the needles is a black art, but it works for all sorts of cells, even those resistant to chemical methods, so it is sometimes still useful.

Is there some state of the art Handbook (Springer Taylor&Francis type) that you could recommend on physical methods of Transfection that goes into the physics of it?

Transfection by heat shock is also a possibility. Anything that creates transient pores on the cell membrane should work, at least in theory.

You can use chemicals too.
