AB  - The problem of sodium and potassium in the attosecond pulse train (APT) as a kicking field is considered. The goal is to investigate the possibility of the kicking field to generate, in general, any secondary radiation. The modifications of the energy bands and the kick-induced currents are examined. Simple local pseudopotentials have been proposed and used. It is demonstrated that the APT generates secondary radiation in a wider spectral range similar to high-order harmonic generation (HHG). This radiation has been found to have a form of periodic complex peak compositions decreasing in intensity with the period approximately equal to the doubled angular frequency of the driving field. This is a new effect. A physical explanation of this effect is given.

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.

AB  - A new method for the high-order harmonic generation on the quantum dots is proposed. Interaction of the kicking laser field with a single-electron cylindrical quantum dot without and in the presence of an external magnetic field is considered. The finite hard wall model and heterostructured semiconductor quantum dot are assumed in order to provide relation to real system which could be studied in an experiment. In particular, GaAs/AlxGa1-xAs quantum dot is examined throughout the paper. Harmonics to a very high-order are obtained which is significant for the attosecond pulse generation. This result can be explained on the basis of the quantum-confined Stark effect. During the kick, the electron energy is increased and it is associated with the pronounced quantum-confined Stark effect in the energy spectrum. The electron transitions to the inner shells give such harmonic emission as a result. It is shown that the range of the harmonic spectrum is strongly dependent on the pulse duration. The influence of a realistic form of kick present in experiments, as the Gaussian approximation for delta function, to the harmonic emission is examined.

AB  - The dynamics of a hydrogen atom in a spherical box under the action of a strong infrared femtosecond laser is numerically investigated. The spherical box is introduced to model collisions of ionized electrons with neighboring atoms to model their influence on high-order harmonic generation. The physical situation appropriate for such application is considered in detail. The presence of tunneling in the process is investigated. In the strong field limit this consideration is extended including a dressing approach in the calculation. The harmonic spectrum is calculated for a small radius of the sphere assuming a high gas pressure. The intensities of the harmonic lines are reduced and the envelope of the spectrum is strongly modified with respect to the plateau of harmonics. The inclusion of the dressing approach in the calculation can significantly modify this result. The situation is changed if a kicking electric field is added at the moment when ionization probability has local maximum. The electron kinetic energy is drastically increased, and as a consequence of the dynamic Stark shifts in the kicking field, and an unusual electron recombination is possible. The odd harmonics of a very high-order and a somewhat different form of plateau of harmonics appear. The intensities of so obtained single-atom harmonic emission are dramatically enhanced. To check the reliability of the model with an impenetrable spherical box, high-pressure argon gas is also considered in relation to the single atom high-order harmonic generation.

These shapes are predicted assuming correspondence under some conditions with the alternating kicking field. Unusually kicked dynamics is suggested. It is shown that such kicked dynamics leads to generalized Rabi oscillations with the positive energy states included and participation of the excited states. The correspondence with the real pulse is established emphasizing such unusually kicked dynamics. The approach is verified on the one-dimensional (1D) hydrogen atom and calculation of the known results for ionization probability.

The discrete time is introduced and the problem with the time-dependent Schrödinger equation is reduced to solving the eigenvalue equation. Constant phase δ corresponding the origin of time becomes, in this way, an important unknown parameter. The physical reason for such approach is the model for laser phase noise. It is present in reality and usually not included into considerations. The sodium atom in the ground state is immersed in alternating (AC) electromagnetic field with frequency in extreme ultraviolet (XUV, wavelengths shorter than 100 nm) region. The AC Stark shift and polarizability are considered and the estimation of the AC Stark shift is given. Our examinations show that energy shift has anomalously strong dependence of δ and laser phase noise introduces significant uncertainty in experimental observation of AC Stark shift. Modification of 3s atomic wave function at high enough strength of electric filed due the phase noise is also shown.

This gives credence to the conjecture that the spectrum is dense in the relevant region of the first quasienergy zone. The band structure retain practically unaltered.

AB  - The problem of anti-unitary symmetry breaking in the model of a standard spin-1/2 quantum kicked rotor in an inhomogeneous magnetic field is examined in relation to the localization properties. It is shown that the functional form of the spin-dependent term in the kicking potential (not the anti-unitary symmetries) is responsible for localization length changes. Our numerical results for the proposed functional form yield evidence of an anomalous and continuous growth of the localization length with an increase in the magnitude of the magnetic field.

AB  - A simple analytic local pseudopotential has been suggested for silicon. This pseudopotential has four adjustable parameters ( beta 1/ beta 2, C1, C2, C3) of which two are taken to give the values of W(111) and W(311) used by Cohen and Bergstresser (1966) and beta 1/ beta 2 is taken from Animalu and Heine (1965), leaving one parameter which the authors choose to obtain a fit. The band structure, reflectivity spectrum and valence density of states were calculated on the basis of this pseudopotential and compared with the experimental results and the corresponding non-local pseudopotential calculations. It is shown that the local pseudopotential approach to silicon can give at least as good results as the more complicated non-local approaches of recent years. This is due to the inclusion of form factors for larger reciprocal lattice vectors (g2>(2 pi /a)211) which other workers have taken as zero. From the results of the present paper it becomes apparent that an adequate estimate of the influence of non-local features can be made only after investigations of the possibilities of the local pseudopotential.
