A negative energy particle is a particle whose binding energy is larger than its rest mass. This is easiest to understand for massive particles. The potential well of a black hole is (in some sense) infinitly deep. Hence, if you put a particle deep enough into the well its binding energy will become bigger than its rest mass.

Step 1: Define the Potential Energy V. The potential energy is 0 inside the box (V=0 for 0<x<L) and goes to infinity at the walls of the box (V=∞ for x<0 or x>L). We assume the walls have infinite potential energy to ensure that the particle has zero probability of being at the walls or outside the box.The single-particle energy levels on a ring move as a function of the flux and experience avoided crossings. Each such crossing leads to dissipation when the level is occupied by an electron.As the particle moves along the magnetic field lines into a stronger magnitude field, the parallel energy of the particle is converted into rotational energy and its Larmor radius increases. However, its magnetic moment remains invariant because the magnetic field does no work and the total kinetic energy of the particle is conserved.Kinetic energy is the energy an object has because of its motion. If we want to accelerate an object, then we must apply a force. Applying a force requires us to do work.
