can anyone explain a bit about Spin Quantum No ?.Kindly explain proerly.
 
Physics news on Phys.org
In quantum mechanics,All particles have 4 quantum number.And these quantum numbers explain some structure of particles.
for instance:
principle quantum number (n):this quantum number is related to the orbit of electron around the proton and it is related to the energy of states.
angular momentum quantum number(l):
This is related to the momentum of particle.
magnetic quantum number(ml)
it is related to the magnetic features of particle(this explanation is very lacking sorry)
and last.
spin:spin is related with (rougly)rotation around its own axis.
and we show that spin up or spin down.

can you demostrate any example of Spin Quantum No.Kindly let me know the idea.Any
help would be highly appreciated.
 
You should try to ask a more specific question, or at least tell us what you have studied so far.

there is not any mathmatical calculation on spin Quantum no.How should i evaluate Spin
Quantum no.Can you show any example for spin Quantum No.

Did you look any course book or text ?
in that link there are several mathematical formulations of spin calculations.

I am reading WHAT IS A QUANTUM FIELD THEORY?" A First Introduction for Mathematicians. The author states (2.4 Finite versus Continuous Models) that the use of continuity causes the infinities in QFT: 'Mathematicians are trained to think of physical space as R3. But our continuous model of physical space as R3 is of course an idealization, both at the scale of the very large and at the scale of the very small. This idealization has proved to be very powerful, but in the case of Quantum...
Thread 'Lesser Green's function'
The lesser Green's function is defined as: $$G^{<}(t,t')=i\langle C_{\nu}^{\dagger}(t')C_{\nu}(t)\rangle=i\bra{n}C_{\nu}^{\dagger}(t')C_{\nu}(t)\ket{n}$$ where ##\ket{n}## is the many particle ground state. $$G^{<}(t,t')=i\bra{n}e^{iHt'}C_{\nu}^{\dagger}(0)e^{-iHt'}e^{iHt}C_{\nu}(0)e^{-iHt}\ket{n}$$ First consider the case t <t' Define, $$\ket{\alpha}=e^{-iH(t'-t)}C_{\nu}(0)e^{-iHt}\ket{n}$$ $$\ket{\beta}=C_{\nu}(0)e^{-iHt'}\ket{n}$$ $$G^{<}(t,t')=i\bra{\beta}\ket{\alpha}$$ ##\ket{\alpha}##...
