Driven isotropic Heisenberg spin chain with arbitrary boundary twisting angle: exact results.
We consider an open isotropic Heisenberg quantum spin chain, coupled at the ends to boundary reservoirs polarized in different directions, which sets up a twisting gradient across the chain. Using a matrix product ansatz, we calculate the exact magnetization profiles and magnetization currents in the nonequilibrium steady state of a chain with N sites. The magnetization profiles are harmonic fu...
متن کاملExact solution of the mixed spin-1/2 and spin-S Ising-Heisenberg diamond chain
The geometric frustration in a class of the mixed spin-1/2 and spin-S Ising-Heisenberg diamond chains is investigated by combining three exact analytical techniques: Kambe projection method, decoration-iteration transformation and transfer-matrix method. The ground state, the magnetization process and the specific heat as a function of the external magnetic field are particularly examined for d...
متن کاملQuantum spin transistor with a Heisenberg spin chain
Spin chains are paradigmatic systems for the studies of quantum phases and phase transitions, and for quantum information applications, including quantum computation and short-distance quantum communication. Here we propose and analyse a scheme for conditional state transfer in a Heisenberg XXZ spin chain which realizes a quantum spin transistor. In our scheme, the absence or presence of a cont...
متن کاملQuasilocal Conserved Operators in the Isotropic Heisenberg Spin-1/2 Chain.
Composing higher auxiliary-spin transfer matrices and their derivatives, we construct a family of quasilocal conserved operators of isotropic Heisenberg spin-1/2 chain and rigorously establish their linear independence from the well-known set of local conserved charges.
متن کاملExact 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...
