# Modern approaches for the theoretical description of multiparticle scattering and nuclear reactions

## Abstract

A review of novel approaches to solution of multiparticle scattering problems in the area above three-body breakup together with the review of new computational technologies which provide very effective and ultrafast realization of the novel approaches with ordinary PC are given. The novel direction presented here is based on two key points: a new formulation of the quantum scattering theory in a discrete Hilbert space of stationary wave packets and the massive-parallel solution of the resulted matrix equations with usage of ultrafast graphic processors (the so called GPU-computations). For the reader's convenience, a short review of the modern GPU calculations for the medicine, physics, military applications etc. is presented.
