Two Identical Particles w/ Spin State s

Click For Summary

Discussion Overview

The discussion centers on the system of two identical particles with a defined spin state, exploring the implications of symmetric and antisymmetric spin states. Participants examine how these states relate to the overall spin of the system and the role of the Hamiltonian in determining energy states.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions how to handle the defined spin state s for two identical particles, suggesting that the treatment differs for symmetric and antisymmetric states.
  • Another participant notes that the total spin depends on the individual spins, indicating that 1/2 + 1/2 results in a symmetric state, while 1 + 1 leads to an antisymmetric state.
  • A participant challenges the assertion that 1 + 1 = 1, stating that antisymmetric spin implies the particles occupy different energy states and queries the ratio of symmetric to antisymmetric spins.
  • Another reply emphasizes that the Hamiltonian influences the energy levels associated with different spin states, suggesting that vector summation can lead to the conclusion that 1 + 1 = 1 in certain contexts.

Areas of Agreement / Disagreement

Participants express differing views on the implications of symmetric and antisymmetric spin states, with no consensus reached on the definitions or relationships between the spins and their energy states.

Contextual Notes

There are unresolved assumptions regarding the definitions of spin states and the specific Hamiltonian in question, as well as the mathematical steps involved in proving the relationships discussed.

what would the system of two identical paritcles with a spin, let's say s? I figure its different for symmetrical and anti-symmetrical spin states but how do you deal with the defined spin state s.

It depends on the spin of the particles. 1/2 + 1/2 = 1 is symmetric,
but 1+1=1 is antisymmetric.
 
How is 1 + 1 = 1?
The definition of an antisymmetric spin means that they are in different energy states.
S+1/S -- isn't this the ratio of symmetric to antisymm spins? How would you even begin to prove this?
 
It depends on the hamiltonian which energy the different spin states posess!

1+1 = 1, if one does vector sum.
