Boris Vainberg's Abstract
Slowing down of the wave packets in quantum graphs
The problem of creating compact optical delay devices is studied. One
of possible applications of such a device is synchronizing the work
of fast optical elements and much slower electronics. The goal is to find
optical media where a delay accompanied by the transparency. It will
be shown that an optical line which can be approximated by a
necklace-type
quantum graph has this property. The general truncated periodic
Schrödinger operator also will be discussed.
The work is joint with S. Molchanov.
