... We should note at this point that lifting the 2nd order limitations, not as easy though, may open the way of implicating the theory to wider range interactions such as the quadruple coupling. Generally, the multipole expansions have been discussed at length elsewhere [7]. 3.3. Inversion electric dip ...

Quantum Mechanical Interference in the Field Ionization of Rydberg
... We now compute the Hamiltonian, and thus, the eigenenergies and energy eigenstates, of a Rydberg atom subject to an electric field. We first review the conventions used when describing the energy levels of an atom. For our purposes, there are four quantum numbers required to fully specify an energy ...

Renormalization without infinities – an elementary tutorial
... We also encounter the phenomenon of dimensional transmutation characteristic for renormalizable field theories with dimensionless coupling constants. Section 10 shows that one can explicitly calculate the renormalized solution in terms of a running coupling constant. The freedom in the choice of the ...

Spectral Analysis of Nonrelativistic Quantum Electrodynamics
... where ∆x is the Laplacian on R3 , and the potential V (x) acts as a multiplication operator, [V ψ](x, σ) := V (x)ψ(x, σ). Moreover, the Z2 factor in the definition of Hel accounts for the spin of the electron. Under the assumption that V ∈ L2 ∩ L∞ (R3 ; R), the Hamiltonian Hel is selfadjoint on the ...
