Spontaneous Scalarization and Boson Stars

We study spontaneous scalarization in Scalar-Tensor boson stars. We find that scalarization does not occur in stars whose bosons have no self-interaction. We introduce a quartic self-interaction term into the boson Lagrangian and show that when this term is large, scalarization does occur. Strong self-interaction leads to a large value of the compactness (or sensitivity) of the boson star, a ne...

construction of vector fields with positive lyapunov exponents

in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...

Massive Particle Fields, with Momentum Matrices

Including translation matrices in covariant non-unitary Poincaré representations alters the construction of massive particle fields from canonical unitary fields. The conventional procedure without spacetime translation matrices determines covariant fields that transform by matrix representations of the homogeneous Lorentz group combined with a differential operator representation of the Poinca...
