Interaction effects on random Dirac fermions
T. Fukui
We study a Dirac fermion model with three kinds of disorder as well as a marginal interaction which forms the critical line of conformal field theory. Computing scaling equat…

Disordered d-wave superconductors with chiral symmetry
T. Fukui
A two-dimensional lattice model for d-wave superconductor with chiral symmetry is studied. The field theory at the band center is shown to be in the universality class of U(2n)/O(2…

A coherent state associated with shape-invariant potentials
T. Fukui, N. Aizawa
An algebraic treatment of shape-invariant potentials is discussed. By introducing an operator which reparametrizes wavefunctions, the shape-invariance condition can be related to a…
