This is an IBM movie about how they move single atoms: http://www.youtube.com/watch?v=oSCX78-8-q0
There are often some "wavish" pattern around atoms on these pictures, like below some of them marked with red triangles:
Are these patterns real?
For example, it can be disturbances in sublayer? Or it can be observable quantum non-locality of atoms?
Or this can be just imperfection of microscopic device.
What is this?
