“…For instance, we take two trajectories with p yi 1 = −p yi 2 and p zi 1,2 = 0, which contribute to the ridge (p y = 0, p z = −T z +p C ) and have δp C z 1 = δp C z 2 , yielding ∆ϕ = 0 according to Eq. (11). In this way the remarkable relation between the main lobe of the quantum interference pattern and the PMD ridge due to Coulomb focusing is confirmed.…”

“…This follows from Eqs. (11) and (14), and the condition δp C z 1 + δp C z 2 = 0, fulfilled for these trajectories. In the case of multiple recollisions (at small values of the final |p x |), the ridge position is closer to zero: p (0) z = −T z +p C , wherep C is positive and determined by multiple recollisions, see Eq.…”

“…The reference beam of the holography scheme [6] is the directly ionized electron wave packet, while the signal beam is the electron wave packet scattered off the ionic core during recollision. This concept of strong-field holography enables to extract time-resolved information on the underlying electron dynamics [7][8][9] and on the molecular structure [10][11][12][13][14].…”

Holographic interferences in strong-field ionization beyond the dipole approximation: The influence of the peak and focal-volume-averaged laser intensities

et al. 2019

In strong-field ionization interferences between electron trajectories create a variety of interference structures in the final momentum distributions. Among them, the interferences between electron pathways that are driven directly to the detector and the ones that rescatter significantly with the parent ion lead to holography-type interference patterns that received great attention in recent years. In this work, we study the influence of the magnetic field component onto the holographic interference pattern, an effect beyond the electric dipole approximation, in experiment and theory. The experimentally observed nondipole signatures are analyzed via quantum trajectory Monte Carlo simulations. We provide explanations for the experimentally demonstrated asymmetry in the holographic interference pattern and its non-uniform photoelectron energy dependence as well as for the variation of the topology of the holography-type interference pattern along the laser field direction. Analytical scaling laws of the interference features are derived, and their direct relation to either the focal volume averaged laser intensities, or to the peak intensities are identified. The latter, in particular, provides a direct access to the peak intensity in the focal volume.

“…In extended Higgs models, the leading contribution arises from the two-loop level Barr-Zee type diagram [180][181][182][183][184][185][186][187][188][189][190][191][192][193][194]. For supersymmetric models, a large contribution is generated from the one-loop level diagram [11,[195][196][197][198][199][200][201][202][203][204][205], together with the two-loop level diagrams [11,[206][207][208][209][210][211][212][213].…”

Nuclear electric dipole moment in the cluster model with a triton: Li7 and B11

2019

We calculate the electric dipole moment (EDM) of the nuclei 7 Li and 11 B in the cluster model with α ( 4 He) and triton ( 3 H) clusters as degrees of freedom. The 7 Li and 11 B nuclei are treated in the two-and three-body problem, respectively, using the Gaussian expansion method, assuming the one meson exchange P, CP-odd nuclear forces. We find that 7 Li and 11 B have larger sensitivity to the CP violation than the deuteron. It is also suggested that the EDMs of 7 Li and 11 B, together with those of 6 Li, 9 Be and the 1/2 + 1 excited state of 13 C, obey an approximate counting rule accounting for the EDM of the cluster and the α − N polarization. We show their sensitivity on the hadronic level CP violation in terms of the chiral effective field theory, and discuss their role in probing new physics beyond the standard model.

“…Atoms and molecules irradiated by an intense laser pulse can produce high-order harmonic generation (HHG) [1][2][3][4][5][6][7][8][9][10][11][12][13]. Under the influence of the strong laser field, an electron can be ionized from the bound state, and accelerated in the continuum state, finally it can recombine with the ion and gives rise to the emission of extreme ultraviolet (XUV) radiation [10,14].…”

Cooper minimum structure of high-order harmonic spectra from atoms or molecules has been extensively studied. In this paper, we demonstrate that the crystal harmonic spectra from an ultrashort mid-infrared laser pulse also exhibit the Cooper minimum characteristic. Based on the accurate band dispersion and k-dependent transition dipole moment (TDM) from the first-principle calculations, it can be found that the harmonic spectra from MgO crystal along Γ-X direction present a dip structure in the plateau, which is originated from the valley of TDM by examining the distribution of the harmonic intensity at the k-space. The Cooper minimum feature in crystal HHG will pave a new way to retrieve the band information of solid materials by using HHG from the ultrashort mid-infrared laser pulse.PACS numbers:
