Stimulated wave of polarization in 1D Ising chain
arXiv:quant-ph/0501022 · doi:10.1103/PhysRevA.71.062338
Abstract
It is demonstrated that in one-dimensional Ising chain with nearest-neighbor interactions, irradiated by a weak resonant transverse field, a stimulated wave of flipped spins can be triggered by a flip of a single spin. This analytically solvable model illustrates mechanisms of quantum amplification and quantum measurement.
