... spin in the i − th layer is determined by two parameters which are the angle with its NN in the adjacent plane, say αi,i+1 , and the azimuthal angle βi formed with the c axis. Since there is no competing interaction in the xy planes, spins in each plane are parallel. In this paper we use the steepes ...

When Einstein tried to describe such a space, it differed wildly from rigid classical Euclidean space due to curvature and so he was left without a valid mathematical model to describe bent space and make pr ...

Canonical quantization

In physics, canonical quantization is a procedure for quantizing a classical theory, while attempting to preserve the formal structure, such as symmetries, of the classical theory, to the greatest extent possible.Historically, this was not quite Werner Heisenberg's route to obtaining quantum mechanics, but Paul Dirac introduced it in his 1926 doctoral thesis, the ""method of classical analogy"" for quantization, and detailed it in his classic text. The word canonical arises from the Hamiltonian approach to classical mechanics, in which a system's dynamics is generated via canonical Poisson brackets, a structure which is only partially preserved in canonical quantization.This method was further used in the context of quantum field theory by Paul Dirac, in his construction of quantum electrodynamics. In the field theory context, it is also called second quantization, in contrast to the semi-classical first quantization for single particles.
