Simple derivation of the lindblad equation

WebbTherefore, to reveal the behaviors of heat transport in the system, we will numerically solve the steady state of the master equation (15) as well as the steady-state heat currents. At first, we mainly take two coupling regimes as examples, one is the strong coupling with g = 0.015 ω 0 , and the other is the ultrastrong coupling with g = 0.45 ω 0 . WebbThe Lindblad equation is an evolution equation for the density matrix in quantum theory. It is the general linear, Markovian, form which ensures that the density matrix is Hermitian, …

The Lindblad master equation describes the evolution of various types of open quantum systems, e.g. a system weakly coupled to a Markovian reservoir. Note that the H appearing in the equation is not necessarily equal to the bare system Hamiltonian, but may also incorporate effective unitary dynamics arising from the system-environment interaction.
