    • openAccess   A pedagogical approach to the Magnus expansion 

      Blanes, Sergio; Casas, Fernando; Oteo, J. A.; Ros, J. Institute of Physics (2010-07)
      Time-dependent perturbation theory as a tool to compute approximate solutions of the Schrödinger equation does not preserve unitarity. Here we present, in a simple way, how the Magnus expansion (also known as exponential ...

    • openAccess   Towards an Efficient Use of the BLAS Library for Multilinear Tensor Contractions 

      Di Napoli, Edoardo; Fabregat Traver, Diego; Quintana-Ortí, Gregorio; Bientinesi, Paolo Aachen University (2014)
      Mathematical operators whose transformation rules constitute the building blocks of a multi-linear algebra are widely used in physics and engineering applications where they are very often represented as tensors. In the ...
