Non-relativistic quantum electrodynamics
Non-relativistic
quantum electrodynamics
is a
low
energy
approximation
of
quantum
electrodynamics which describes the
interaction
of spin
one-half
particles
with the
quantized
electromagnetic field
.
NRQED is an
effective field theory
suitable
for
calculations
in
atomic
and
molecular physics
, for example for
computing
QED
corrections
to
bound
energy levels
of
atoms
and
molecules
.
