Duality in Perturbation Theory and the Quantum Adiabatic Approximation
Duality is considered for the perturbation theory by deriving, given a series solution in a small parameter, its dual series with the development parameter being the inverse of the other. A dual symmetry in perturbation theory is identified. It is then shown that the dual to the Dyson series in quantum mechanics is given by a recently devised series having the adiabatic approximation as leading...
متن کاملSystematic Improvement of Hartree Fock Bogoliubov Approximation with Exponentially Fast Convergence from Variational Perturbation Theory
Variational perturbation theory [1] is a systematic extension of a variational method developed some years ago by Feynman and Kleinert [2], and others [3], and converts divergent perturbation expansions for energy levels and free energies of a quantum mechanical anharmonic oscillator into exponentially fast converging expansions for all coupling strength [1, 4]. This is achieved by perturbing a...
متن کاملConvergence of simultaneous perturbation stochastic approximation for nondifferentiable optimization
In this paper, we consider Simultaneous Perturbation Stochastic Approximation (SPSA) for function minimization. The standard assumption for convergence is that the function be three times differentiable, although weaker assumptions have been used for special cases. However, all work that we are aware of at least requires differentiability. In this paper, we relax the differentiability requireme...

متن کاملStructuring quantum effects: superoperators as arrows
We show that the model of quantum computation based on density matrices and superoperators can be decomposed in a pure classical (functional) part and an effectful part modeling probabilities and measurement. The effectful part can be modeled using a generalization of monads called arrows. We express the resulting executable model of quantum computing in the programming language Haskell using i...
