Constructing algebraic groups from their Lie algebras
Willem de Graaf
A connected algebraic group in characteristic 0 is uniquely determined by its Lie algebra. In this paper an algorithm is given for constructing an algebraic group in characteristic…
Inclusive electron scattering off 4He
S. Bacca, H. Arenhoevel, N. Barnea +2
Inclusive electron scattering off 4He is calculated exactly with a complete treatment of the final state interaction within a simple semirealistic potential model. We discuss resul…
Decoherence induced by interacting quantum spin baths
Davide Rossini, Tommaso Calarco, Vittorio Giovannetti +2
We study decoherence induced on a two-level system coupled to a one-dimensional quantum spin chain. We consider the cases where the dynamics of the chain is determined by the Ising…
Some recent results in scalar quantum field theory in globally hyperbolic asymptotically flat spacetimes
Valter Moretti
Some recent results obtained by the author and collaborators about QFT in asymptotically flat spacetimes at null infinity are summarized and reviewed. In particular it is focused o…
Constructing algebraic Lie algebras
Claus Fieker, Willem de Graaf
We give an algorithm for constructing the algebraic hull of a given matrix Lie algebra in characteristic zero. It is based on an algorithm for finding integral linear dependencies…
Upper limits to surface force disturbances on LISA proof masses and the possibility of observing galactic binaries
Ludovico Carbone, Giacomo Ciani, Rita Dolesi +5
We report on the measurement of parasitic surface force noise on a hollow replica of a LISA (Laser Interferometer Space Antenna for the observation of gravitational waves) proof ma…
