Preface

The Program Committee warmly welcomes all our distinguished delegates and guests to attend the 2021 2nd International Conference on Physics and Engineering Mathematics (ICPEM 2021), the Online International Conference to be held on November 13th-14th, 2021. ICPEM is an annual event that focuses on the various state-of-the-art advances and innovations in Applied Physics and Engineering Mathematics. It aims to provide a forum for researchers, engineers and academicians to exchange new ideas and application experiences, establish business or research relations and find global partners for future collaboration in the fields of Physics and Engineering Mathematics. The ICPEM 2021 conference received around 141 submissions from all over the world; all submissions went through a rigorous peer review process where each submitted paper was reviewed by at least two experts from the area. Based on the review reports, 69 papers were selected for oral presentation in the conference and included in the Proceedings of 2021 2nd International Conference on Physics and Engineering Mathematics. On behalf of the Program Committee of the 2021 2nd International Conference on Physics and Engineering Mathematics, we would like to thank all the people who have contributed to the conference this year. In particular, we would like to thank all referees for their review work. We would like to thank the keynote speakers and session chairs for spending their valuable time to support the conference. We also would like to thank all the authors for contributing their papers to the conference. Finally, we are particularly grateful to all the organizers and sponsoring institutions for the generous support they have offered to this conference. We hope and believe that every participant will enjoy the academic atmosphere brought by the contributors of the conference. We look forward to a more successful conference next year.

A new combination of Hankel and sparsity-promoting dynamic mode decompositions and its application to the prediction of plasma turbulence

A new combined use of dynamic mode decomposition algorithms is proposed, which is suitable for the analysis of spatiotemporal data from experiments with few observation points, unlike computational fluid dynamics with many observation points. The method was applied to our data from a plasma turbulence experiment. As a result, we succeeded in constructing a quite accurate model for our training data and it made progress in predictive performance as well. In addition, modal patterns from the longer-term analysis help to understand the underlying mechanism more clearly, which is demonstrated in the case of plasma streamer structure. This method is expected to be a powerful tool for the data-driven construction of a reduced-order model and a predictor in plasma turbulence research and also any nonlinear dynamics researches of other applied physics fields.

Plexcitonic strong coupling: unique features, applications, and challenges

There are, recently, remarkable achievements in turning light-matter interactions into strong coupling quantum regime. In particular, room temperature plexcitonic strong coupling in plasmon-exciton hybrid systems can bring promising benefits for fundamental and applied physics. Herein we will review theoretical insights and recent experimental achievements in plexcitonic strong coupling and divide this review into two main parts. The first part will briefly introduce the general field of strong coupling, including its origin and history, physical mechanisms and theoretical models, as well as recent advanced applications of strong coupling, such as the quantum or biochemical devices enabled by optical strong coupling. The second part will zoom in and concentrate on plexcitonic strong coupling by introducing its unique features and new potentials (such as single-particle ultrastrong coupling, strong coupling dynamics in femtosecond scale) and discussing the limitations and challenges of plexcitonic strong coupling, which will also be accompanied by potential solutions such as the microcavity-engineered plexcitonics, spectral hold burning effects, and metamaterial-based strong coupling. Finally, we will summarize and conclude this review, highlighting the future research directions and promising applications.

ANALYSIS DIMENSIONS OF CREATIVITY IN STEM INTEGRATED PROJECT-BASED LEARNING

This study aims to analyze the dimensions of creativity in integrated project-based learning in Science, Technology, Engineering, and Mathematics (STEM). The research method uses descriptive statistical analysis. This research was conducted on students of the Physics Education Study Program in Banjarmasin. The research subjects consisted of 24 physics teacher prospective students programming Applied Physics courses. Data obtained through tests, questionnaires and interviews. Data were analyzed by calculating the normality test, difference test, and N Gain. The results showed the order of increasing the percentage of N Gain in the creativity dimension from the lowest to the highest, namely the person dimension, the press dimension, the product dimension, and the process dimension. The strength of this research is to train the creativity of prospective teacher students through project creation by integrating STEM fields that combine cognitive, affective, and psychomotor abilities by exploring the problems that exist in their neighborhood. Further research on the dimensions of creativity in other learning models is needed to explore student creativity continuously and sustainably in order to produce quality resources.

Laughlin anyon complexes with Bose properties

Two-dimensional electron systems in a quantizing magnetic field are regarded as of exceptional interest, considering the possible role of anyons—quasiparticles with non-boson and non-fermion statistics—in applied physics. To this day, essentially none but the fractional states of the quantum Hall effect (FQHE) have been experimentally realized as a system with anyonic statistics. In determining the thermodynamic properties of anyon matter, it is crucial to gain insight into the physics of its neutral excitations. We form a macroscopic quasi-equilibrium ensemble of neutral excitations - spin one anyon complexes in the Laughlin state ν = 1/3, experimentally, where ν is the electron filling factor. The ensemble is found to have such a long lifetime that it can be considered the new state of anyon matter. The properties of this state are investigated by optical techniques to reveal its Bose properties.

NEW EXHIBITS OF ITEMS WITH CHAMPLEVE ENAMELS IN SUMY REGIONAL MUSEUM (PRELIMINARY REPORT)

During 2018—2020 items with Champleve enamels were presented to Sumy Regional Museum by Sumy residents, S. I. Gutsan and R. A. Bobkov. They were shown at an exhibition dedicated to the 100th anniversary of the Museum in September 2020. The collection consists of more than 70 items (tabl. 1). There are brooches (horseshoe-shaped, triangular, round), pendants (cruciform, lunnula), chains, bracelets, diadems, torques, appliquй, finger-rings, trapezoidal pendants, spurs etc. Because these finds were kept in private collections and were presented to the Museum by their owners, the items could be considered accidental finds except location of them was more or less accurate. Preliminary analysis of things from the collection allowed us to determine the following. The area of finds includes different areas of Sumy region, but those found in Sumy’s suburbs significantly dominate, and by dating they mostly belong to the second stage of development of East European Champleve enamels, according to E. Gorokhovskyi — to the middle and second half of 3rd century. Metal and enamel of things were analyzed by the researchers of The Institute of Applied Physics of NASU using an X-ray fluorescence spectrometer. Situation around archeological monuments requires a rapid reconstruction, adaptation of science to new unfavorable conditions. This publication is prompted by an attempt to obtain maximum information from sources whose reliability is questionable. Moreover, the things analyzed in this publication are of great importance for solving many important questions of archeology, in particular, for the reconstruction of the Slavonic peoples’s genesis.
