    Goal-oriented adaptive finite element methods with optimal computational complexity

    We consider a linear symmetric and elliptic PDE and a linear goal functional. We design and analyze a goal-oriented adaptive finite element method, which steers the adaptive mesh-refinement as well as the appr...

    Electron-light interaction in nonequilibrium: exact diagonalization for time-dependent Hubbard Hamiltonians

    We present a straightforward implementation scheme for solving the time-dependent Schrödinger equation for systems described by the Hubbard Hamiltonian with time-dependent hop**s. The computations can be per...
