B. Bagchi et al., Generalized continuity equation and modified normalization in PT-symmetricquantum mechanics, MOD PHY L A, 16(31), 2001, pp. 2047-2057
The continuity equation relating the change in time of the position probabi
lity density to the gradient of the probability current density is generali
zed to PT-symmetric quantum mechanics. The normalization condition of eigen
functions is modified in accordance with this new conservation law and illu
strated with some detailed examples.
