Quantum spin system with on-site exchange in a magnetic field G. P
... the exchange interaction and D is the single-ion anisotropy. Formally, the Hamiltonian (3) can be rewritten into the equivalent form in terms of spin –1/2. Let us express each spin Si over the sum Si = σ iA + σ iB of two classical spins σ iα = ±1/ 2 on the ith site. This transformation is non-one-t ...

... and deeper, question namely whether there is strict causality in nature. The history of science has always being the search for causal connections between events and therefore it is hard to believe that strict causality does not hold true. However there are empirical facts that have led many people ...
