Derivation of the Nonlinear Schrödinger Equation from First Principles
... The fundamental rule of quantum mechanics is: the equations governing the quantum counterpart of a classical system are found by replacing the linear momenta pk with the operators − ih̄ ∂/∂xk and treating all functions of the coordinates as multiplication operators. This rule has produced an immense ...

Reivelt, K., Vlassov, S. (2014) Quantum SpinOff Learning Station
... In this Station we look for a smooth transition from quantum mechanics to the study of complex quantum mechanical systems, or nanosystems. We will do this by introducing nanotechnology, which is currently an area of intense scientific research due to a wide variety of potential applications. This is ...

From Quantum mechanics to nanoparticles and their applications
... From this small exercise it should be clear that a nanoparticle is not a particle in the sense we have learned in quantum mechanics, but it is in fact a cluster of atoms. On the other end, it is not like a solid we learned about in learning station number VII (Semiconductors) either, as the number o ...
