Spin coherent state
WebIn the rst part, basic properties of the Coherent State of a linear Harmonic Oscillator are described using Schroedinger Wave Mechan-ics. Then coherent states being a "over-complete" set have been used as a tool for the evaluation of the path integral. After that, spin states just analogous to the coherent state of a Harmonic oscillator are de- WebIn the physics literature they are called the spin-coherent states because the spin is classified with the irreducible representations of SU(2) (see ). These coherent states have …

Starting with two electrons in a spin-singlet state in the first dot, we shuttle one electron over to ... WebWe use the spin coherent state P-representation [13] to modify the standard TDMF, and present an efficient ap-proach, which gives excellent agreement with the exact solution of the many-spin quantum problem already for rather small systems (up to 20 spins). By applying this method to large-scale problems, we study the interesting
