Unfortunately, in general, neither symmetric nor anti-symmetric wavefunctions can be said to be eigenfunctions of the Hamiltonian. The wave function for an electron in a hydrogen-like atom with atomic number Z in the ground state is RZ(r)=2(Z/a0)^(3/2)*exp(-Zr/a0). RZ(r) is an eigenfunction of HZ=1/(2m)*p^2-Ze^2/(4πε0r). But RZ(r) is not an eigenfunction of HZ'=1/(2m)*p^2-Z'e^2/(4πε0r), Z'≠Z. Let us consider the case where a hydrogen-type atom with atomic number Z and a hydrogen-type atom with atomic number Z' are sufficiently separated from each other. And each electron in each atom is in the ground state. The anti-symmetric wave function Ψ={RZ(r1)RZ'(r2)-RZ(r2)RZ'(r1)}/2^(1/2) is not an eigenfunction of the Hamiltonian H=1/(2m)*p1^2-Ze^2/(4πε0r1)+1/(2m)*p2^2-Z'e^2/(4πε0r2). It should be an ironclad rule of quantum mechanics that the wave function is an eigenfunction of the Hamiltonian.

For some stupid reason I couldn’t figure out what I would do if it wasn’t a cubical box due to the equations in my textbook simply writing L^3, but you writing them separately as lx,ly,and lz made it make way more sense, thank you so much :D. Sometimes these simple concepts can be overlooked.

This video shows under the right conditions, the quantization of a field is naturally produced. The ground state energy is induced via Euler’s contain column analysis. The containment of the column must come in to play before over buckling occur or the effect will not work. The system response in a quantized manor when force is applied in the perpendicular direction. Bonding at the points of highest probabilities and maximum duration( peeks and troughs) of the fields/sheet produced a stable structure out of three fields People say I am just plucked guitar strings. I said you can not make structures with vibrating guitar strings or harmonic oscillators. kzbin.info/www/bejne/raOlpKSfepWpfZYsi=waT8lY2iX-wJdjO3 In the model, “U” shape waves are produced as the loading increases and just before the wave-like function shifts to the next higher energy level. Over-lapping all the waves frequencies together using Fournier Transforms, I understand makes a “U” shape or square wave form. If this model has merit, seeing the sawtooth load verse deflection graph produced could give some real insight in what happened during the quantum jumps. You can reproduce my results using a sheet of Mylar* ( the clear plastic found in school folders.

Do the terms [aa|bb] & [ab|ba] represent the exact coulomb and exchange integrals (with double integration over x1 and x2), or do they represent the mean field approximation (with a single integral over solely x2?) I can’t tell if the Fock operator results from the substitution of the approximate mean-field integrals for J and K, or if the Fock operator is a natural result (without any need for substitution in this derivation) of assuming the total electronic wave-function takes the form of a slater determinant of one-electron spin orbitals

I think theres something wrong with your partition function notation Q, when you sum over the states and use index i, the E_i would also change , so you change/sum over the energy level and not the states which you say it will do? Confusing

the un(x,t) function serves as the basis of U(x,t) wave. Is un(x,t) quantised here? or components withing un(x,t) are quantised? I feel un(x,t) shouldn't be quantised since we get to choose the coeff. An, so unless An are equal to 0,1,2,3...(integral values) I feel I'm thinking something wrong please correct me and share the correct way to look at this problem(What exactly is quantised here)

You're the king of chemistry, doing the job of 10 of my professors as what appears to be from your latest video's comment section, pure altruism. I am constantly at the verge of being expelled from my chemistry major for being so bad at chemistry in my university (in my nation you get banned from your major nationwide if you fail an exam thrice) yet your videos always come in clutch. 🤗
