3. Angular Momentum States.
... consistent with torques applied to the body. This means that in a Cartesian coordinate system, the angular momentum of a body around each of the three perpendicular axes may take any value consistent with the magnitude of the angular momentum. Thus, if electron spin were a classical quantity, the ma ...

The path integral representation kernel of evolution operator in
... The path integral method was proposed by R. Feynman as a new approach [1] to the solution of quantum mechanical problems. Nowadays it became one of the most powerful methods in theoretical physics. Many applications (see [2–5]) of this method are devoted to diverse important problems. In articles [6 ...

Why do we observers perceive ourselves are fairly local in real space as opposed to Fourier space, say, which according to the formal ...

Magnetic order in nuclear spin two-dimensional lattices due to electron–electron interactions
... the effective mass. We emphasise the non-analytic behaviour on the modulus q ¼ jqj, which cannot be derived within a standard Fermi liquid theory. This linear jqj dependence is indeed the necessary dependence for a nuclear ferromagnet as discussed above. The problem here is, however, the sign of thi ...

Exact and Effective Pair-Wise Potential for Protein-Ligand Interactions Obtained from a Semiempirical Energy Partition
... Computational methods are of great interest to evaluate binding affinities between proteins and ligands, with many applications in structure-based drug design (SBDD) [1]. A complete description of the correspondent molecular interactions, including the short-range polarization plus charge transfer ( ...
