AB  - The kicked rotor (KR) is one of the basic models in connection with chaos and quantum chaos. A possible application of an attosecond pulse train as a kicking field in the KR is theoretically examined for the first time. This version of the KR is denoted as an atto-KR. It seems to be the most realistic version of the KR because it takes into account the real form of the kicking field as it appears in the experiments. The atto-KR is investigated from the classical and the quantum aspects. In the classical case, a new map instead of the Chirikov standard map is proposed. It may be useful in appropriate experiments with the classical chaos. In the quantum case, the atto-KR gives satisfactory results. Phenomena such as dynamical localization and quantum resonances appear in the undisturbed form. It may be also used for examining the influence of the quantum effects on classical chaos and diffusion. © 2021 IOP Publishing Ltd

AB  - The problem of underlying classical dynamics chaotic and regular in quantum and classical billiards and their influence on high-order harmonic generation are investigated. The results concerning the Bunimovich stadium and rectangular billiards are given. The quantum billiard with an electron in a micron-sized quantum dot is assumed. Then the quantum dot in the kicking electric field is considered. The reflection symmetry of billiards is crucial for the emergence of harmonics. The harmonics can have different forms from an ideal δ-spike to a barely recognizable form. For the Bunimovich stadium with fully chaotic dynamics, emission peaks in the spectrum can have such a barely recognizable shape for some initial states and this may depend on the electric field orientation. In the case of rectangular quantum billiard with regular dynamics, emission peaks in the form of ideal δ-spikes always appear. Thus, it would be a new experimentally verifiable signature of quantum chaos. The same problem is also but strictly classically considered. It has been shown that the emission spectrum with high-order harmonics exists in this case as well. Comparison of intensities of harmonics for Bunimovich stadium, circular and rectangular billiards is given. It is highlighted that the harmonic peaks for the Bunimovich stadium are lower than for the other two regular billiards. This can be the criterion for the existence of classical chaos as well. © 2019
