Special Issue Information

Dear Colleagues,

In the interaction between a strong femtosecond laser and gaseous or solid targets, many ultrahigh-order nonlinear phenomena can occur, such as high harmonic generation, tunneling ionization, double ionization, laser-induced electron diffraction, laser-induced ultrafast current, etc. To model the experimentally detected signal, the most reliable method is solving a time-dependent Schrӧdinger equation (TDSE) or some other expanded dynamic equation. Many semi-analytic models were also developed to help people understand the physical process more clearly.  

Indeed, the output signal is largely governed by the symmetry property of the target. Thus, it is natural to analyze the data obtained experimentally or numerically from the viewpoint of symmetry. As people obtain more and more knowledge about the connection between the symmetry property of the target and the feature of an ultrafast signal, it becomes easier to predict the characteristics of the output signal. Additionally, the ultrafast output signal could be an effective tool to detect the symmetry property of an unknown target. In particular, to achieve the ultrafast time resolution of monitoring phase transitions with the symmetry property changed, it is critical to study the causal relationship between the symmetry property of the sample and the features of the output signal.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Symmetry is an international peer-reviewed open access monthly journal published by MDPI.

Solid-state high-order harmonic generation (HHG) now is a strong tool for detecting target properties, like band structure, Berry curvature and transition dipole moments (TDMs). However, the physical mechanism of high-order harmonic generation (HHG) in solids has not been fully elucidated. According to previously published works, in addition to the inter-band polarization, intra-band currents, and anomalous currents due to Berry curvature, there is another term which will be called the mixture term (MT). Taking monolayer ZnO as a sample, it is found that the intensity of the mixture term, which has been ignored for a long time in previous works, actually is comparable with other terms. Additionally, we compare the orientation-dependent HHG spectra that originated from different mechanisms. It is found that the inter-band and mixture HHG show similar orientation features. Meanwhile, Berry curvature only produces perpendicularly polarized even harmonics, and intra-band perpendicularly polarized even harmonics show special orientation features which can be explained by the orientation-dependent group velocity. This work will help people understand the mechanisms of solid-HHG better. Full article
