The last three decades have seen considerable advances in the theory and implementation of quantum mechanical methods,both relativistic and nonrelativistic.Coupled with the remarkable advances in computing technology,high-level calculations can now be performed that accurately interpret experimental results,and...
Due to tunnelling, in quantum theory, a particle will always reach this region so there shouldn’t be positive energy bound states. This intuition of no embedded eigenvalues is incomplete due to the fact that bumps can cause reflections even when the bumps are smaller than the energy, so an...

The latter term corrects the quantum-mechanical theory for relativistic effects, e.g., due to the presence of heavy elements or large magnetic moments leading to significant spin-orbit interactions in the system. However, this phenomenological approach, whose attractiveness lays essentially in its ...

In the quantum field theory, the Lee model is established to study how the processes depicted by ⇄V⇄N+θ could influence the physical state and wave function renormalization [32]. The Feshbach resonance theory [38] and the Anderson model [39] are also different forms with similar ...

The Euclidean Green functions have the advantage that they can be directly related to Lagrangian field theory and at the same time can be used to reconstruct the underlying quantum theory [2], [3], [4]. With this connection in mind...

In the quantum theory, 1/P0 has to be understood as the inverse energy operator (P0)−1 whose eigenvalue when acting on an energy eigenstate coincides with the inverse of the energy eigenvalue. 4 To get the four-velocity, one has to multiply this expression by the Lorentz boost factor ...
