Can anyone tell me what exactly the "Heisenberg Hamiltonian" is???

I found it in an article related to: the renormalization group.

Thanks in advance.

[tex] H=\sum_i \sum_{j \ne i} J_{ij} S_i \cdot S_j [/tex]

If I am wrong, what exactly the Heisenberg picture of operators?

Inha iscorrect, Heisenberg picture of operators means thatelhinnaw said:

[tex]O_H=e^{-iHt}O_Se^{iHt}[/tex]

[tex]O_H, O_S[/tex] are operators in Heisenberg and Schroedinger pictures.

but I thout it was related to solid state of matter. the hamiltonian of the linking energies.

yes???

Yes. That's what I posted, magnetism is a property of solids too.
