N-fold Supersymmetry and Quasi-solvability Associated with X_2-Laguerre Polynomials
Toshiaki Tanaka
We construct a new family of quasi-solvable and N-fold supersymmetric quantum systems where each Hamiltonian preserves an exceptional polynomial subspace of codimension 2. We show…

Existence of Different Intermediate Hamiltonians in Type A N-fold Supersymmetry
Bijan Bagchi, Toshiaki Tanaka
Type A N-fold supercharge admits a one-parameter family of factorizations into product of N first-order linear differential operators due to an underlying GL(2,C) symmetry. As a co…
