Classical Analog of Quantum Light Cones in 1D and 2D Dipole Systems

The speed at which the magnetic perturbation or information propagates along a chain of classical dipoles is discussed. While in the quantum information counterpart for long‐range interacting spins, where the speed of propagation of the information plays a paramount role, it is not strictly clear whether a light cone exists or not, numerical evidence that interacting dipoles do posses a linear light cone shortly after a perturbation takes place...
