This book presents a complementary perspective to Schrödinger
theory of electrons in an electromagnetic field, one that does not
appear in any text on quantum mechanics. The perspective, derived
from Schrödinger theory, is that of the individual electron in the
sea of electrons via its temporal and stationary-state equations of
motion – the ‘Quantal Newtonian’ Second and First Laws. The
Laws are in terms of ‘classical’ fields experienced by each
electron, the sources of the fields being quantum-mechanical
expectation values of Hermitian operators taken with respect to the
wave function. Each electron experiences the external field, and
internal fields representative of properties of the system, and a
field descriptive of its response. The energies are obtained in
terms of the fields. The ‘Quantal Newtonian’ Laws lead to
physical insights, and new properties of the electronic system are
revealed. New mathematical understandings of Schrödinger theory
emerge which show the equation to be intrinsically
self-consistent. Another complimentary perspective to
Schrödinger theory is its manifestation as a local effective
potential theory described via Quantal Density Functional theory.
This description too is in terms of ‘classical’ fields and
quantal sources. The theory provides a rigorous physical
explanation of the mapping from the interacting system to the local
potential theory equivalent. The complementary perspective to
stationary ground state Schrödinger theory founded in the theorems
of Hohenberg and Kohn, their extension to the presence of a
magnetic field and to the temporal domain – Modern Density
Functional Theory -- is also described. The new perspectives are
elucidated by application to analytically solvable interacting
systems. These solutions and other relevant wave function
properties are derived.
