Thermodynamics of integrable chains with alternating spins.
We consider a two-parameter (c̄ , c̃) family of quantum integrable Hamiltonians for a chain of alternating spins of spin s = 1/2 and s = 1. We determine the thermodynamics for low-temperature T and small external magnetic field H, with T << H. In the antiferromagnetic (c̄ > 0 , c̃ > 0) case, the model has two gapless excitations. In particular, for c̄ = c̃, the model is conformally invariant and has ...
متن کاملIntegrable quantum spin chains and their classical continuous counterparts
We present certain classical continuum long wave-length limits of prototype integrable quantum spin chains, and define the corresponding construction of classical continuum Lax operators. We also provide two specific examples, i.e. the isotropic and anisotropic Heisenberg models. ∗Proceedings contribution to the Corfu Summer Institute on Elementary Particle Physics and Gravity Workshop on Non C...
متن کاملEntanglement in spin chains with gradients
We study solvable spin chains where either fields or couplings vary linearly in space and create a sandwich-like structure of the ground state. We find that the entanglement entropy between two halves of a chain varies logarithmically with the interface width. After quenching to a homogeneous critical system, the entropy grows logarithmically in time in the XX model, but quadratically in the tr...
متن کاملAn Entanglement Study of Superposition of Qutrit Spin-Coherent States
Considering generalized concurrence as the criterion of entanglement, we study entanglement properties of superposition of two qutrit coherent states, as a function of their amplitudes. These states may attain maximum entanglement or no entanglement at all, depending on the choice of the parameters involved. The states revealing maximum entanglement also display the maximum violations of the Be...
متن کاملIntegrable multiparametric quantum spin chains
Using Reshetikhin’s construction for multiparametric quantum algebras we obtain the associated multiparametric quantum spin chains. We show that under certain restrictions these models can be mapped to quantum spin chains with twisted boundary conditions. We illustrate how this general formalism applies to construct multiparametric versions of the supersymmetric t-J and U models. PACS: 71.20.Ad...
