Optimally focusing wave packets of a free particle — •Christoph Tempel, Karl Vogel, Lev Plimak, and Wolfgang P. Schleich — Institute of Quantum Physics, Ulm University

Appropriately prepared real-valued one-dimensional wave packets can focus [1,2] during a short period of time before they spread – even in the absence of any force. We consider a family of measures of width to describe this effect quantitatively and determine the optimally focusing wave packet for each member of this family numerically. Furthermore, we examine the properties and time evolution of these wave packets.
