Bound state in quantum mechanics
In quantum physics, a bound state is a quantum state of a particle subject to a potential such that the particle has a tendency to remain localized in one or more regions of space. The potential may be external or it may be the result of the presence of another particle; in the latter case, one can equivalently define … See more • A proton and an electron can move separately; when they do, the total center-of-mass energy is positive, and such a pair of particles can be described as an ionized atom.

However, it is also evident that there is always at least one totally symmetric bound state, no matter how small λ becomes ( i.e., no matter how shallow the well becomes).
WebThe observation that bound states in a potential well correspond to -V_0 < E < 0 −V 0 < E < 0 isn't too surprising; after all, the same statement is almost true classically. The difference is in the left inequality, that E E is … WebThe quantum states for systems involving confining potentials have associated both quantized wavefunctions and energies. In other words, for such systems all the allowed quantum states are bound states. Note A confining potential, such as the harmonic oscillator or the infinite barrier, satisfies that V(x) → ∞ for x → ± ∞.

WebThe quantum mechanics of bound states with discrete energy levels is well understood. The quantum mechanics of scattering processes is also well understood. However, the quantum mechanics of moving bound states is still debatable. When it is at rest, the space-like separation between the constituent particles is the primary variable.
