Abstract:

This project has been a collaboration with the group of Professor Eilbeck, at the Department of Mathematics of the Heriot-Watt University, at Edinburgh (U.K.). We have studied conditions of existence and properties of breathers in some anharmonic quantum lattices. This kind of problems evolves the determination of the spectrum of large sparse matrices, and supercomputers seem to be the natural tool to be used in this framework.
