    "abstract": "By applying the higher order Darboux algorithm to an exactly solvable non\nHermitian ${\\cal{PT}}$ symmetric potential, we obtain a hierarchy of new\nexactly solvable non Hermitian ${\\cal{PT}}$ symmetric potentials with real\nspectra. It is shown that the symmetry underlying the potentials so generated\nand the original one is {\\it nonlinear pseudo supersymmetry}. We also show that\nthis formalism can be used to generate a larger class of new solvable\npotentials when applied to non Hermitian systems.",
