Abstract
⺠The new concept of the locally negative effective mass introduced and studied. ⺠Tests presented via a few exactly solvable toy models. ⺠Manifest energy dependence found to guarantee the stability of the system. ⺠The emergence of anomalous states found related to the decrease of the energy threshold. ⺠Most of the toy-model properties (localization, nodal number growth) found generic.
