Abstract

Abstract The excitation of a quantum oscillator at transitions between stationary states by wavelet pulses with zero and nonzero area as a function of their duration and amplitude is studied. The excitation from the ground state is examined in detail, together with the specific features of this process during excitation from excited states. Analytical expressions for the main characteristics of excitation probability under weak and strong perturbation of quantum oscillator were obtained within limits of strict consideration. Particularly, it was found that, on a qualitative and quantitative level, there is no difference between excitation by pulses with zero and non-zero area.

Dynamics of Time Evolution of Quantum Oscillator Excitation by Electromagnetic Pulses

Valery Alexandrovich Astapenko, FRANK B. ROSMEJ, Evgeniya V. Sakhno

Abstract The dynamics of time evolution of quantum oscillator excitation by electromagnetic pulses is investigated theoretically for an arbitrary field amplitude in a pulse. We consider a harmonic oscillator without damping and excitation between stationary states. The general formula for the excitation of quantum states as a function of time is derived in terms of instantaneous energy of an associated classical oscillator in the field of an electromagnetic pulse. The derived expression is used in detailed analysis of the time dependence of the quantum oscillator excitation probability beyond the range of perturbation theory for various pulse parameters including total excitation from the ground state, excitation from excited states, and excitation spectra.

Time dependence of quantum oscillator excitation by electromagnetic pulses

Valery Alexandrovich Astapenko, FRANK B. ROSMEJ, Evgeniya V. Sakhno

The paper is devoted to the theoretical investigation of time dependences of quantum oscillator excitation by electromagnetic pulses for arbitrary values of field amplitude in the pulse. We consider the harmonic oscillator without relaxation and excitation between stationary states. The general formula for excitation of quantum states as function of time is derived in terms of instant energy of associated classical oscillator in the field of electromagnetic pulse. Thus, it is established that time dependence of quantum oscillator excitation is completely determined by the energy of the associated classical oscillator at given moment of time. Using derived expression time dependence of quantum oscillator excitation is investigated in details including total excitation from ground state, excitation from excited states, total excitation probability and corresponding excitation spectra.

Pulsed excitation of a quantum oscillator: A model accounting for damping

Valery Alexandrovich Astapenko, Timur Bergaliyev, Sergey V. Sakhno

Abstract This article proposes a model that accounts for damping of a quantum oscillator (QO) during pulsed excitation. Our model is based on the Schwinger formula, which calculates oscillator’s excitation probability through the energy of an associated classical damped oscillator. We utilize this model to describe the influence of damping on temporal and spectral dependences of QO excitation, induced by electromagnetic pulses with exponential and double exponential envelopes. The oscillator excitation is analyzed in terms of transition probability between stationary states after pulse termination. Here, we present an analytical description of these dependences, along with numerical results. Specifically, we derive analytical expressions that depict the saturation effect during pulsed excitation, taking into account the damping of a QO. The evolution of the temporal dependence of the excitation probability with a change in the damping constant is numerically traced. We demonstrate that the number of maxima in this dependence is determined by the values of pulse parameters and the damping constant.

Peculiar Features of Quantum Oscillator Excitation by Pulses with Different Envelopes

Valery Alexandrovich Astapenko

We investigate the excitation of a quantum harmonic oscillator by pulses with different envelopes in terms of the excitation probability during the action of a pulse. The majority of attention is given to the dependence of the probability on the pulse duration and the pulse carrier frequency for three envelopes: exponential, double exponential, and rectangular. The choice of these envelopes makes it possible to cover various features of the excitation of a quantum oscillator by an external pulse. In particular, the presence of weak and strong excitation modes is established, for each of which the dependences of the process probability on pulse parameters are studied.

Abstract The excitation of a linear quantum oscillator (LQO) upon a collision with a charged particle moving in a rectilinear trajectory is analyzed. The probability and the cross section of the process are calculated beyond the framework of perturbation theory for different charges of the incident particle, including multiply charged ions. The excitation between the LQO stationary states, as well as total excitation from the ground state, are considered. The characteristic features of the process depending on the problem parameters are analyzed.

The spectroscopic correspondence principle for the time evolution of quantum transitions under the action of electromagnetic pulses

Valery Alexandrovich Astapenko, Evgeniya V. Sakhno

Abstract This work is dedicated to the generalization of the spectroscopic correspondence principle to the time dependence of the evolution of a dipole-allowed quantum transition in a two-level system (TLS) under the action of an electromagnetic pulse (EMP). The formulas for the time dependence of the absorbed EMP energy for excitation of a classical oscillator and an oscillator of a transition in a TLS are derived within the framework of the first order of perturbation theory. It is shown that in the case of zero width of a transition line (or in case of zero damping constant γ for a classical oscillator) classical and quantum approaches give the same results for arbitrary EMP parameters (duration and carrier frequency). A noticeable distinction between the time dependences of the absorbed energy for a classical oscillator and a quantum TLS with a Lorentz spectral profile is observed for sufficiently long pulses.
