- Abstract summary: We have dealt with the second quantization of Schrodinger and its effects on the path of a particle.
This generalization leads to a modified Schrodinger which affects the particle through a modified quantum potential and a new term in the continuity equation.

- Abstract: A causal interpretation of the quantum world needs second quantization in
order to cover phenomena like creation and annihilation of particles, and this
leads to quantum field theory. The causal effects of the second quantization
can be described through a new quantum potential. In this article we have dealt
with the second quantization of Schrodinger and its effects on the path of a
particle. This generalization leads to a modified Schrodinger which affects the
particle through a modified quantum potential and a new term in the continuity
equation. We have shown that these effects can provide a framework for the
explanation of the creation and annihilation phenomena and other effects of
quantum field theory on the development of a particle.
