Derivation of the Lindblad Equation for Open Quantum Systems …
WebbWe present a derivation of the Lindblad equation - an important tool for the treatment of non-unitary evolutions - that is accessible to undergraduate students in physics or mathematics with a basic background on quantum mechanics. We consider a specific case, corresponding to a very simple situation, where a primary system interacts with a … WebbWe use the full form of this equation, which makes only the weak-coupling and Markovian approximations, to calculate the cooling power for a simple model of laser cooling. We compare its predictions with two other time-local master equations: the secular approximation to the full Bloch-Redfield equation, and the Lindblad form expected for … floating youtube always on top

Webb12 juli 2024 · Away from equilibrium, the properties of open quantum systems depend on the details of their environment. A microscopic derivation of a master equation (ME) is therefore crucial. Of particular interest are Lindblad-type equations, not only because they provide the most general class of Markovian MEs, but also since they are the starting … WebbThe starting point of the Bloch-Redfield formalism is the total Hamiltonian for the system and the environment (bath): H = HS + HB + HI, where H is the total system+bath Hamiltonian, HS and HB are the system and bath Hamiltonians, respectively, and HI is the interaction Hamiltonian. WebbRecently, Brasil, Fanchini, and Napolitano brasil provided a relatively simple derivation of the Lindblad equation starting from a general Hamiltonian and the Liouville-von Neumann equation in a Markov approximation and a rotating … floating youtube edge extension
