... minimum of the potential energy, however in regions with no charge, we know from our discussion of the solutions to Laplace’s equation that there can be no local minima (or maxima) to the electric potential, therefore a particle cannot be in stable equilibrium in an electrostatic field. (Yeah, it is ...

... You know that the concept of potential energy is not applicable in relativistic situations. One consequence of this is that the only fully relativistic quantum theories possible are quantum field theories. However, there do exist situations where a particle’s motion is “slightly relativistic” (e.g., ...

... Lawrence and Wybourne have considered an elastic bar under static longitudinal compression beyond the Euler instability leading to two stable equilibrium positions around which the transverse vibrations of the beam occur. It turned out that quantum tunnelling between the two minima is in principle p ...
