Semiclassical approximation of excitations in spin-1 Heisenberg antiferromagnets
... The above model is also known as the Rotor Model. At g = 0 we get a perfectly ordered state with anti-ferromagnetic coupling. Non zero g destroys ordering. It can be proved that even for small values of g the effective contribution to the Hamiltonian due to the second term is very small and thus can ...

Self-adjoint operators and solving the Schrödinger equation
... U (t) = e−itH is referred to as the time evolution of the Hamiltonian H. The solution ψ(t) = U (t)ψ0 also has properties which one would expect from the time evolution of a state in a closed quantum mechanical system. Mathematically, this is expressed by the fact that U = (U (t))t∈R is a strongly c ...

Measuring the quantum mechanical wave function
... Fortunately the proposed scheme requires us only to measure one variable Ð position Ð and this can be done with very high precision indeed [9]. So nothing can stop me from measuring the distributions Pr (n ; Ln) for a set of truly quantum particles. And no one can prevent me from entering this measu ...
