Welcome to the DynAMoS research group!

The development of ultrashort laser pulses, first in the femtosecond and more recently in the attosecond domain, allows to follow the real-time dynamics of complex, anharmonic, correlated many-body systems, yielding a wealth of detailed dynamical information which was formerly unavailable. The interpretation of those measurements require detailed theoretical simulations, which in turn demand the incorporation of the quantum nature of atomic motion. However, the direct solution of the time-dependent Schrödinger equation demands the use of a very large mesh of grid points or a large number of basis functions to represent the spreading of the wave packet in a variety of molecular phenomena.

Consequently, there is a sustained interest in the development of new theoretical and computational approaches that may cope accurately with wave packet propagation within the typical spatial and time scales. To the purpose of reducing the computational cost, a large number of semiclassical and hybrid quantum-classical methodologies have been developed. These methods aim to exploit the local character of classical dynamics in phase space, which results in a significant reduction of the computational cost. Our research group is focused in method development to describe the quantum dynamics of ultrafast processes, building for instance novel quantum-mechanical mappings to equivalent quasi-classical systems to describe a variety of phenomena. We apply these methods to a diversity of systems with potential applications in nanotechnology, ranging from the hydrogen storage in nanostructrured materials and the study of quantum dots to the optical properties of conjugated molecular systems used as building blocks of organic semiconductors and solar cells
