Dynamics of the dissipative two-state system
WebDec 17, 2009 · We introduce a random variable approach to investigate the dynamics of a dissipative two-state system. Based on an exact functional integral description, our method reformulates the problem as that of the time evolution of a quantum state vector subject to a Hamiltonian containing random noise fields. This numerically exact, non … WebUnder low-temperature, weakly dissipative conditions, we observe unusual, nonmonotonic population dynamics when the two-level system is initially placed in its ground state. …

Webdifference of the two diabatic states is much larger than the bandwidth of the bosonic bath [29]. However, more understanding of LZ dynamics at intermediate times is needed. This is a time rangein which the transitionshave not fully taken place and the energy difference of the two diabatic states is still within the bath’s bandwidth [30]. WebThe interaction between the qubits gives rise to an effective σx ⊗ σz geometric term [7] with strength χ. 3. Coupling to the bath In order to study the system’s dissipative dynamics, …

WebDec 6, 2006 · The decoherence of a two-state system coupled with a sub-Ohmic bath is investigated theoretically by means of the perturbation approach based on a unitary transformation. It is shown that the decoherence depends strongly and sensitively on the structure of environment.
