The scaling law of the arrival time of spin systems that present pretty good transmission
Pablo Serra, Alejandro Ferrón, Omar Osenda
The pretty good transmission scenario implies that the probability of sending one excitation from one extreme of a spin chain to the other can reach values arbitrarily close to the…

Exact solution of a family of staggered Heisenberg chains with conclusive pretty good quantum state transfer
Pablo Serra, Alejandro Ferrón, Omar Osenda
We construct the exact solution for a family of one-half spin chains explicitly. The spin chains Hamiltonian corresponds to an isotropic Heisenberg Hamiltonian, with staggered exch…
