Summary:
This paper reports a two-dimensional quantum walk (QW) model to describe the spatio-temporal behavior of the dressed photon (DP) energy transfer. DP is a quantum field that is created as the result of interaction among photons and electrons in a nanometer-sized complex system. Experimental studies have suggested that the temporal behavior of the DP energy transfer should be described by the QW model, not by a conventional random walk model. Thus, the QW model was used to study the efficiency of the DP creation on the tip of a conventionally used fiber probe device. Numerical calculations successfully evaluated the dependences of the DP energy transfer on basic physical quantities; the dependences on the ratio between the DP-hopping energy and the DP-phonon coupling energy, and on the phase of the unitary matrix in the spatio-temporal evolution equation.
