WebWe develop a new theory of the spin-Peierls transition in spin-\textonehalf{} Heisenberg chains, treating the phonons in a mean-field random-phase approximation (RPA) as in previous work, but calculating the relevant response functions of the spin system using the procedure of Luther and Peschel. We show that the RPA on the phonons (and therefore … WebApr 14, 2024 · Charge and spin density waves are typical symmetry broken states of quasi one-dimensional electronic systems. They demonstrate such common features of all incommensurate electronic crystals as a spectacular non-linear conduction by means of the collective sliding and susceptibility to the electric field. These phenomena ultimately … Peierls' theorem states that a one-dimensional equally spaced chain with one electron per ion is unstable. This theorem was first espoused in the 1930s by Rudolf Peierls. It can be proven using a simple model of the potential for an electron in a 1-D crystal with lattice spacing . The periodicity of the crystal creates energy band gaps in the $${\displ… how to unround in tableau
