Expressing Decoherence with Spectral and Stochastic Methods
D. Salgado, J. L. Sanchez-Gomez
We suggest a novel proposal to express decoherence in open quantum systems by jointly employing spectral and stochastic methods. This proposal, which basically perturbs the unitary…
Comment on ``Dynamics of open quantum systems initially entangled with environment: Beyond the Kraus representation'' [PRA 64, 062106 (2001)]
D. Salgado, J. L. Sanchez-Gomez
We correct a mistake in a result reported in [PRA 64, 062106 (2001)], where it is rightfully argued that initial correlations between a system and its environment may render the sy…
Damped Quantum Interference using Stochastic Calculus
D. Salgado, J. L. Sanchez-Gomez
It is shown how the phase-damping master equation, either in Markovian and nonMarkovian regimes, can be obtained as an averaged random unitary evolution. This, apart from offering…
Lindbladian Evolution with Selfadjoint Lindblad Operators as Averaged Random Unitary Evolution
D. Salgado, J. L. Sanchez-Gomez
It is shown how any Lindbladian evolution with selfadjoint Lindblad operators, either Markovian or nonMarkovian, can be understood as an averaged random unitary evolution. Both mat…
Generalized model-independent approach to intrinsic decoherence
D. Salgado, J. L. Sanchez-Gomez
A formalism is presented to express decoherence both in the markovian and nonmarkovian regimes and both dissipative and nondissipative in isolated systems. The main physical hypoth…
