Chiral symmetry breaking in the 3-d Thirring model for small $N_f$
We study the dynamical breaking of chiral symmetry in the 3-d Thirring model for a small number of fermion species.

CP Phases in Models with Some Fermion Masses Vanishing and/or Degenerate
We count the number of CP breaking phases in models with $SU(2)_L\times U(1)_Y$ and $SU(2)_L\times SU(2)_R\times U(1)_{B-L}$ electroweak gauge groups

Dark Matter Halos in a Secondary Infall Model
We calculate the density profiles of virialized halos in the case of structure evolving hierarchically from a scale-free Gaussian delta-field

Degenerate neutrinos from a supersymmetric A_4 model
We investigate the supersymmetric A_4 model recently proposed by Babu, Ma and Valle. The model naturally gives quasi-degenerate neutrinos that
