Abstract

We study excitation transfer in a spin chain in presence of noise. To model noise, we assume that each ‎qubit of the spin chain is interacting with a Bosonic environment and has Markovian evolution. ‎We derive the explicit form of master equation both in global and local approaches. Comparing the ‎results of each approach, we discuss the noise effect on excitation transfer and in addition to that we ‎show that the results of local approach are not a limiting case of global approach‎.‎‎
