Will the wave function of a particle be the same in the two cases: 1) When the particle is isolated i.e. as a free or independent particle. 2) When the particle is bonded with other similar particles to constitute a composite particle. For example, consider an isolated quark and a quark which is bonded with other quarks by strong force to form a proton. Will the wave function of the two quarks be similar? Or will the wave function of the quark in the latter case be the same as the wave function of the proton sice that quark is always a part of that proton? Will the wave function of any particle be changed in accordance to the composite particle when it is bonded with other similar particles rather than when it is in isolation or independent? Kindly clarify.
