The Massive Schwinger Model in a Fast Moving Frame
We present a non-perturbative study of the massive Schwinger model. We use a
Hamiltonian approach, based on a momentum lattice corresponding to a fast
moving reference frame, and equal time quantization.Comment: contribution to Lattice'98 including: 2 style files

Generalized Aharonov-Bohm effect, homotopy classes and Hausdorff dimension
We suggest as gedanken experiment a generalization of the Aharonov-Bohm
experiment, based on an array of solenoids. This experiment allows in principle
to measure the decomposition into homotopy classes of the quantum mechanical
propagator. This yields information on the geometry of the average path of
propagation and allows to determine its Hausdorff dimension.Comment: 14 pages, LaTeX + 3 figures, P
Cosmological dynamics of scalar field with non-minimal kinetic term
We investigate dynamics of scalar field with non-minimal kinetic term.
Nontrivial behavior of the field in the vicinity of singular points of kinetic
term is observed. In particular, the singular points could serve as attractor
for classical solutions.Comment: 6 pages, 3 figures, title is changed, some refs added, to be
