Single crystal growth of Heisenberg spin ladder and spin chain

... Low dimensional magnets have attracted great attention because of their simplicity in theoretical models, novel quantum phenomena and relation to high temperature superconductivity. Among them, quasi-1D systems such as spin ladders and spin chains have found their realization in several materials, e ...

Lecture 33: Quantum Mechanical Spin

... • For spin, the quantum number, s, can only take on one value – The value depends on the type of particle – S=0: Higgs – s=1/2: Electrons, positrons, protons, neutrons, muons,neutrinos, quarks,… – s=1: Photons, W, Z, Gluon – s=2: graviton ...

Spin-orbital separation in the quasi-one

... When viewed as an elementary particle, the electron has spin and charge. When binding to the atomic nucleus, it also acquires an angular momentum quantum number corresponding to the quantized atomic orbital it occupies. Even if electrons in solids form bands and delocalize from the nuclei, in Mott i ...
