For this Hamiltonian we derive a closed formula for the metric operator and compute the Hermitian counterpart of the non-Hermitian Hamiltonian.eninfo:eu-repo/semantics/closedAccessimpulse conditionquasi-Hermitianmetric operatorRiesz basisHermitian counterpartON THE METRIC OPERATOR FOR A NONSOLVABLE NON-HERMITIAN MODELArticle10.1016/S0034-4877(15)30013-62-s2.0-849308283094163Q340375WOS:000356748400005Q3
