Exact and numerical results for the dimerized spin - orbital chain
We establish exact results for the one-dimensional spin-orbital model for special values of the four-spin interaction V and dimerization parameter δ. The first exact result is at δ = 1/2 and V = −2. Because we find a very small but finite gap in this dimerized chain, this can serve as a very strong test case for numerical and approximate analytical techniques. The second result is for the homog...
متن کاملQuantitative expression of the spin gap via bosonization for a dimerized spin-1/2 chain
Using results on the mass gap in the sine-Gordon model combined with the exact amplitudes in the bosonized representation of the Heisenberg spin-1/2 chain and one-loop renormalization group, we derive a quantitative expression for the gap in a dimerized spin-1/2 chain. This expression is shown to be in good agreement with recent numerical estimates when a marginally irrelevant perturbation is t...
متن کاملDynamics of transverse correlations in the spin-12 isotropic XY chain with a correlated Lorentzian disorder
Using a numerical approach we examine the dynamics of zz correlations for the spin1 2 isotropic XY chain with random Lorentzian intersite coupling and transverse field at sites that depends linearly on the neighbouring couplings. We study in detail the wave vectorand frequency-dependent zz structure factor at different values of Hamiltonian parameters and temperature. We discuss the changes in ...
متن کاملSpin-wave theory for dimerized ferromagnetic chains
We describe a Peierls dimerization which occurs in ferromagnetic spin chains at finite temperature, within the modified spin-wave theory. Usual spin-wave theory is modified by introducing a Lagrange multiplier which enforces a nonmagnetic state at finite temperature. It is shown that this method gives results in excellent agreement with the density–matrix renormalization group applied to transf...
متن کاملReal time correlations at finite Temperature for the Ising model
After having developed a method that measures real time evolution of quantum systems at a finite temperature, we present here the simplest field theory where this scheme can be applied to, namely the 1 + 1 Ising model. We will compute the probability that if a given spin is up, some other spin will be up after a time t, the whole system being at temperature T . We can thus study spatial correla...
