WebMay 15, 1989 · Abstract. One-dimensional antiferromagnets have exotic disordered ground states. As was first argued by Haldane (1983), there is an excitation gap for integer, but not half-integer, spin. The authors review the arguments for this behaviour based on field-theory mappings, the Lieb-Schultz-Mattis theorem, exactly solvable models, finite-chain ... WebWe investigate dynamical stability of the ground state against a time-periodic and spatially-inhomogeneous magnetic field for finite quantum XXZ spin chains. We use the survival probability as a measure of stability and demonstrate that it decays as P ( t ) ∝ t −1/2 under a certain condition. The dynamical properties should also be related to the level statistics … WebNov 1, 2007 · First, let's take just one spin. There are two possible basis states, "up" and "down". Let the "up" state be represented by the column vector , and the "down" state by . Then the operators for that spin are Now, with two spins, the basis states are up-up, up-down, down-up, and down-down. high risk high reward investments reddit
