Published Apr 14, 2014• 5 citations

Abstract

We study the dynamics of multi-level quantum systems under the influence of electromagnetic field.Basing on the path integral approach to the quantum density matrix and transitions probability we represent functional averaging electromagnetic field influence.We demonstrate that the transition probability can be written as a path integral of real functional (the product of exponent and cosine).The numerical integration algorithm of the transitions probability in energy representation was developed.The numerical simulations of the quantum system dynamics under electromagnetic field action describe the well-known Rabi oscillations, their fluctuations and multi-photon quantum transitions.

We describe multilevel quantum systems dynamics in electromagnetic fields using the influence functional approach in path integration formalism. We obtain equations for the statistical density matrix and the probability of transitions of quantum systems induced by the electromagnetic field. The explicit form of the quantized electromagnetic field influence functional is concretized. Spontaneous transition of the quantum systems, the Rabi oscillations and their fluctuations are obtained. The two#photon photoelectric effect is explained.

The description of interacting multilevel quantum system and quantum electromagnetic ﬁeld in terms of statistical density matrix is considered in path integral approach. The statistical operator and probability transitions of quantum system are represented as mean of electromagnetic ﬁeld inﬂuence functional. The inﬂuence functionals are deﬁned for speciﬁc models of electromagnetic ﬁeld. The explicit form for singleand multimode electromagnetic ﬁeld is concretized in cases when initial state of the ﬁeld is represented by vacuum and pure coherent.

We obtain equations for the probability of transitions of quantum systems induced by the electromagnetic field using the influence functional approach in path integration formalism. For numerical simulations the probability transition reduces to the integration of a real functional path, that allows us to apply modern methods of numerical integration.

Numerical calculations of the probabilities for quantum transitions in atoms and molecules by the path integral method

Alexander Alexandrovich Biryukov, Yana Vladimirovna Degtyareva

The probabilities of molecular quantum transitions induced by electromagnetic field are expressed as path integrals of a real alternating functional. We propose a new method for computing these integrals by means of recurrence relations. We apply this approach to description of the two-photon Rabi oscillations.

The description of two-photon Rabi oscillations in the path integral approach

Yana Vladimirovna Degtyareva, Alexander Alexandrovich Biryukov, Марк Александрович Шлеенков

The probability of quantum transitions of a molecule between its states under the action of an electromagnetic field is represented as an integral over trajectories from a real alternating functional. A method is proposed for computing the integral using recurrence relations. The method is attached to describe the two-photon Rabi oscillations.
