Self-organising phenomena in 2D complex plasma simulations withnon-mono dispersed dust size distributions
Authors: Holen G , Adhikari S , Mishra R , Miloch W J 
Published: March 2024

Abstract
Complex plasma with a variety of continuous and discrete dust grain size distributions are simulated in 2D with molecular dynamics simulations with radial geometry to determine differences in self-organizing phenomena to more realistically represent the actual in situ variations in dust-size. The standard deviation of particle size σ(a) strongly correlates with phase separation and coupling parameter Γ for all distribution types. We observe local differences in bond order parameters and Voronoi diagrams for different size distributions, and our results suggest that phase transition is affected by continuous size distributions, particularly in the binary distribution case. Simulations with discrete size result in artifacts and discontinuities that are not found in the continuous distributions. The use of continuous distributions is observed to be beneficial both for more realistic approximation of complex plasma experiments and to study systems of strongly coupled particles in general.

Published: March 2024

Abstract
The dielectric measurement of neat ethylene glycol monomethyl ether (EGMME), neat ethanol and their binary mixtures have been carried out using time domain technique in frequency range of 10 MHz to 50 GHz at the temperature range from 10 °C to 25 °C with a difference of 5 °C. The frequency domain technique within the frequency range of 20 Hz to 2 MHz is used to obtain complex dielectric permittivity ε*(ω), electrical modulus M*(ω), complex electrical conductivity σ*(ω) and loss tangent (tan δ) at 25 °C. The dielectric spectra obtained using TDR technique are fitted in Cole-Davidson model to extract the dielectric parameters such as static dielectric permittivity (ε
s), relaxation time (τ) and asymmetric distribution parameter (β). These relaxation parameter values are used to predict intermolecular hydrogen bonding between EGMME and ethanol molecules. Furthermore, the inter-molecular interactions through H-bonding between EGMME and ethanol molecules have been confirmed and discussed using Kirkwood correlation factor, excess permittivity, thermodynamic parameter, Bruggeman factor, excess molar volume, excess dielectric permittivity at high frequency and Fourier transform infrared (FTIR) spectra.
Multilayers strategy with a mixed CdTe/ZnTe absorber layer for optical trapping and efficiency improvement in CdTe-based solar – SCAPS modelling

Published: March 2024

Abstract
This work is a theoretical contribution to improving the performance of CdTe-based thin-film solar cells (TFSC) by optimising the collection of photons in the absorber structure. The basic data are retrieved from experimental reference work and the reference structure is as follows: CdS/CdTe/ZnTe with an efficiency of 20.16%, where ZnTe is used as a BSF to limit backward recombination. The first approach is to incorporate a ZnTe thin layer at the CdS/CdTe heterojunction, to subdivide the CdTe active layer into two (02) sub-layers and to identify the optimum structure as a function of their position in the stack. Investigating the work function of back contact materials enables to better enhance the device′s performance and stability. To take into consideration the discontinuities in the material properties, grain boundaries and performance loss factors, the impacts of charge carrier capture cross sections, bulk and interfacial defects are investigated. SCAPS software is employed for all the numerical modelling, which enables to calculate the current-voltage (J-V), power-voltage (P-V), external quantum efficiency (EQE) and other PV parameters and to draw energy band diagram to better appraise charge carrier transportation. The doping level in the CdTe active layer, the thicknesses and external temperature are also investigated to optimize our device properties. In terms of the obtained fill factor (FF) and efficiency (PCE), the performances were improved with the following structure CdS/CdTe/ZnTe/CdTe/ZnTe, FF = 81.6% and PCE = 23.45%, with 500 nm thickness of CdTe. These results are opening a promising new perspective in high efficiency CdTe TFSC.
Non-metricity with boundary terms: 𝖿(𝖰,𝖢) gravity and cosmology
Authors: De Avik , Loo Tee-How , Saridakis Emmanuel N. 
Published: March 2024

Abstract
We formulate f(Q,C) gravity and cosmology. Such a
construction is based on the symmetric teleparallel geometry, but apart
form the non-metricity scalar Q we incorporate in the Lagrangian the
boundary term C of its difference from the standard Levi-Civita Ricci scalar
R̊. We extract the general metric and affine connection field equations,
we apply them at a cosmological framework, and
adopting three different types of symmetric teleparallel affine connections
we obtain the modified Friedmann equations. As we show, we acquire an
effective dark-energy sector of geometrical origin, which can lead to
interesting cosmological phenomenology.
Additionally,
we may obtain an effective interaction between matter and dark energy.
Finally, examining a specific model, we
show that we can obtain the usual thermal
history of the universe, with the sequence of matter and dark-energy epochs,
while the effective dark-energy equation-of-state
parameter can be quintessence-like, phantom-like, or cross the phantom-divide
during evolution.
Vortex creep heating in neutron stars
Authors: Fujiwara Motoko , Hamaguchi Koichi , Nagata Natsumi , Ramirez-Quezada Maura E. 
Published: March 2024

Abstract
Recent observations of old warm neutron stars suggest the presence of a heating source in these stars, requiring a paradigm beyond the standard neutron-star cooling theory. In this work, we study the scenario where this heating is caused by the friction associated with the creep motion of neutron superfluid vortex lines in the crust. As it turns out, the heating luminosity in this scenario is proportional to the time derivative of the angular velocity of the pulsar rotation,
and the proportionality constant J has an approximately universal value for all neutron stars. This J parameter can be determined from the temperature observation of old neutron stars because the heating luminosity is balanced with the photon emission at late times.
We study the latest data of neutron star temperature observation and find that these data indeed give similar values of J, in favor of the assumption that the frictional motion of vortex lines heats these neutron stars. These values turn out to be consistent with the theoretical calculations of the vortex-nuclear interaction.
Thermodynamics for regular black holes as intermediate thermodynamic states and quasinormal frequencies
Authors: Huang Bai-Hao , Hu Han-Wen , Zhao Liu 
Published: March 2024

Abstract
The thermodynamics for regular black holes (RBHs) is considered
under the restricted phase space (RPS) formalism.
It is shown that the RPS formalism seems to hold for RBHs,
however, in order for the extensive thermodynamic parameters to be
independent from each other, the RBHs need to be viewed as intermediate
thermodynamic states in a larger class of black holes (BHs) which
admit both regular and singular states. This idea is checked for
several classes of BHs. In particular, for the electrically
charged Hayward class BHs, it is shown that the regular states
can either be thermodynamically stable or unstable, depending on
the amount of charges carried by the BHs. The quasinormal
frequencies for the Hayward class BHs are also analyzed,
and it turns out that, even for the thermodynamically unstable
regular states, the dynamic stability still holds, at least under
massless scalar perturbations.

Abstract
Photodynamic therapy (PDT) has been widely employed in clinical applications, healthcare, and public health (e.g. cancer research, microbiological control, vector control, etc). The photodynamic action is an advanced oxidation process based on the production of reactive oxygen species (ROS) and singlet oxygen by the excitation of a photosensitizer by specific wavelengths of light in the presence of molecular oxygen. The generation of ROS, which are highly reactive, encourages the use of PDT against recalcitrant pollutants and resistant parasites, a novel approach for PDT applications. Here, we explored recent research in PDT in water and wastewater treatment, elucidating operational conditions, main targets, potentials, and constraints, considering a collection of scientific papers curated by a well-defined research strategy. Retrieved records were filtered by subjects, and data was organized into a content network. Results showed that PDT is a timely alternative to deal with emerging chemical contaminants, resistant microorganisms, and other challenges, raising opportunities for versatile applications and sustainable solutions. Advances in environmental applications of PDT may help reach the Sustainable Development Goal 6 (SDG 6), but also positively impact other SDGs.

Published: March 2024

Abstract
In this article we present a Teaching-Learning Sequence (TLS) on colour performed in the non-formal setting of a vocational stage with a sample of N=38 18-year-old high school students. Based both on previous educational research and the analysis of the characteristics of the Italian high school curriculum, the TLS adopts cooperative experimental investigation activities with low-cost equipment which help students distinguish different physical situations involving the combination of colours; furthermore, it focuses on developing a solid understanding of the connection between the physics and physiology of colour phenomena. The TLS was highly appreciated by students and, thanks in part to the inclusion of advanced topics such as photonic crystals and plasmons, it may have a significant motivational value.
A new educational approach to surface tension and Young-Laplace law by using computer-based simulations
Authors: Battaglia Onofrio Rosario , Termini Giulia , Agliolo Gallitto Aurelio , Fazio Claudio 
Published: March 2024

Abstract
Here we present a pedagogical approach to surface tension phenomena based on a novel mesoscopic fluid model. We show that computer simulations based on this model can provide quantitative results that are consistent with experimental results. We simulate the formation of a two-dimensional liquid droplet without gravity and obtain its surface tension as a result by also verifying Young-Laplace’s law. By controlling some simulation parameters, students can understand step by step how some physical quantities (e.g., the intensity of the interaction between two fluid particles) can affect the behaviour of fluids. This approach will provide students with an explicative model of surface phenomena.
Dulong-Petit’s law and Boltzmann’s theoretical proof from the Kinetic Theory of Gases
Authors: Rosa P , Souza A 
Published: March 2024

Abstract
The main aspect that we will address in this work is the introductory presentation of the empirical law of the specific heats of material bodies, published by Dulong and Petit on April 12, 1819, in the magazine Comptes Rendus. The analytical demonstration of this law appeared for the first time in 1866 in the Doctoral Thesis of the Austrian physicist Ludwig Boltzmann, according to the research carried out by Cássio C. Laranjeiras and presented in his Doctoral Thesis in 2002. In the introduction we discussed how Dulong’s law and Petit played a key role in the subsequent development of a new physics (Quantum Mechanics), when Max Planck changed his research program from electrodynamics to thermodynamics, evidenced in the book: Black Body Theory and the Quantum Discontinuity, 1894-1912, published by Thomas Khun in 1978. Between 1900 and 1912, we observed that fundamental works published by Albert Einstein, Henri Poincaré and Peter Debye explained the mathematical relationship of this empirical law based on Planck’s hypothesis of the quantum of action of blackbody radiation. Despite the controversy over the authorship of the law, whether it would have been formulated in advance by Arago, we agree with Robert Fox that it was the results of Dulong and Petit’s experiments that led to the formulation of the law.
Games for Quantum Physics Education

Published: March 2024

Abstract
As the second quantum revolution comes to pass with its potential to revolutionize our lives, it becomes increasingly relevant to educate the public about quantum mechanics. Quantum literacy is also a formidable challenge and opportunity for a massive cultural uplift, since it fosters the possibility for citizens to engender their creativity and practice a new way of thinking. However, quantum theory is highly counterintuitive, manifesting in a reality we have no direct experience of, and represented by mathematically difficult formalisms. Here, we propose that games can provide a playground for engaging forms of experimental and symbolic literacy accessible to anyone. We discuss the theoretical foundations underlying this idea in the framework of a global educational strategy, illustrate existing examples of its implementation along different dimensions related to educational, citizen-science, and age-related contexts, and envision future challenges.
Understanding the relation between classical and quantum mechanics: prospects for undergraduate teaching
Authors: Mauro M Di , Drago A , Naddeo A 
Published: March 2024

Abstract
Classical and quantum mechanics are two very different theories, each describing the world within its own range of validity. It is often stated that classical mechanics emerges from quantum mechanics in a certain limit. This is known as the correspondence principle. According to Planck’s version of the correspondence principle, classical mechanics is recovered when the limit in which a dimensionless parameter containing Planck’s constant h goes to zero is taken, while Bohr’s version entails taking the limit of large quantum numbers. However, despite what is usually stated in textbooks, the relation between the two theories is much more complex to state and understand. Here we deal with this issue by analysing some key examples, in some of which also the analogously subtle relation between wave and geometric optics is considered. Implications for quantum mechanics teaching at undergraduate level are carefully discussed.
A 5E-based learning experience to introduce concepts relevant in Quantum Physics
Authors: Obbo Joseph , Dillmann Baudouin , Adorno Dominique Persano 
Published: March 2024

Abstract
We here present and discuss a 5E-based learning activity focused on introductory concepts of Quantum Physics experienced at the Bachelor of Electrical Engineering of a Kenyan University. The described constructivist environment aimed at supporting an effective understanding of concepts very relevant in Modern Physics, such as wave-particle dualism, discretization, de Broglie wavelength, Heisenberg Uncertainty principle, atomic models, particle in a box, etc., by triggering a chain of reasoned investigation, inquiry, problem solving, and collaboration with peers. As it is well known, the 5E-based learning cycle is a student-centred instructional approach which helps learners to broaden their views on the concepts and link together the ideas, by means of five phases of instruction: Engagement, Exploration, Explanation, Elaboration, and Evaluation. Our findings show the proposed workflows successfully engaged students into active learning, stimulating the activation of the inquiry process and, at the same time, supporting the clarifying of important experimental and technological aspects of modern physics. This learning path represents a feasible example of a combination of a traditional lecture-based teaching method with laboratory and computational activities.
Innovation, Enterprise and Physics Education: Weaving Paradigms for World of Work
Authors: Jolly Pratibha 
Published: March 2024

Abstract
There are global concerns about the employability potential of the young graduates. Increasingly, the young are expected to contribute to the innovation ecosystem, be economically productive, and capable of being self-employed, enterprising and entrepreneurial. An overview of the national policies and practices is provided to illustrate the sweeping changes being brought about at all levels of education. The paper explores how enterprise and entrepreneurial education can be embedded in mainstream physics education. The assertion is that dynamic and creative teaching-learning environments have long included action-learning in various measures. Case study of work undertaken by the author exemplifies how collaborative student projects provide the opportunity for embedding innovation and enterprise in curricular and cocurrricular activities in transdisciplinary contexts. An overarching perspective highlights challenges, opportunities and implementable action plans.
Physics Education from a decolonial perspective: a case study with Brazilian curriculum
Authors: Mometti C , Tajmel T , Pietrocola M 
Published: March 2024

Abstract
The educational process is characterized as a set of pedagogical actions developed for a particular social group and provided with intentionality. In this sense, every pedagogical action involves an intention, which transfers and reproduces cultural patterns that materialize in social values and traditions. In this context, the postmodern decolonial thinking discussed by Quijano (2019), Mignolo and Walsh (2018), and Abdi (2011) are inserted, as well as the epistemological aspects given by Santos (2020). Thus, with this paper, we seek to present a case study developed in Brazil about the colonial influences that manifest themselves in the science curriculum of the State of São Paulo, Brazil, taking Physics Education as the context for analysis. For that, we used as a method of analysis the Discourse Analysis given by the France perspective about the ideological construction of the discourse. As preliminary results, we identified that the absence of an original Brazilian structure for the construction of the analyzed curriculum corroborates the perspectives of a form of colonization characterized by us as at the primary level, that is, epistemic. With the investigation, we hope to contribute to understanding which the cultural lens that act as a colonizing operator on the set of scientific standards and Brazilian scientific representativeness.
The articulation between the STS Approach and Environmental Education for the contextualization of Acoustics in Physics Teaching
Authors: Moraes Roberto Barreto de , Vianna Deise Miranda 
Published: March 2024

Abstract
Noise pollution presents itself in an invisible, dangerous, and permanent way, with long-lasting consequences. Acoustic discomfort within the school environment affects not only human health but also the quality of verbal communication and student performance. An appropriate acoustic environment contributes to the improvement of the teaching and learning process in addition to enhancing the interpersonal relationships involved in the educational process. Moreover, it is important to introduce acoustics-related subjects, such as environmental noise, into high school science and physics syllabi. As urban noise is a global concern and scope, students may face the need to make decisions related to environmental practices in their future lives, such as those concerning comfortable sound levels. Articulating the STS Approach with Environmental Education, we seek to combine the interdisciplinary content of Acoustics with an environmental awareness that goes beyond mere conservationist reductionism. In addition to the mandatory curricular knowledge, STS Education adopts a scientific and technological education based on a social construction that is culturally and socially contextualized.
Investigating the relationships between students’ reasoning in Socio-Scientific Issues and knowledge about scientific inquiry and modelling
Authors: Sciarretta Walter , Testa Italo 
Published: March 2024

Abstract
In this paper, we investigate the relationships between students’ reasoning about socio-scientific issues and their knowledge about scientific inquiry and modeling. To this aim, we developed a teaching-learning sequence for Italian high school students (10th grade) during which the students were familiarized with the basic aspects of scientific inquiry and modelling and then confronted with the controversial scenario of the closing of a steel manufacture plant in Italy. The results show that students’ knowledge of models and the scientific inquiry does not seem adequate to achieve a sufficient level of competence in socio-scientific reasoning. Implication for teaching practice about physics-based socio-scientific issues will be briefly discussed.
Investigating the trends of developing students’ experimental competency through inquiry-based laboratory approach: A systematic literature review
Authors: Nguyen Thanh Loan , Nguyen Van Bien , Tran Ngoc Chat 
Published: March 2024

Abstract
This systematic literature review aims to analyze research trends in inquiry-based laboratory on the development of students’ experimental competency. The review followed a PRISMA approach. This study applied PRISMA by conducting a comprehensive literature search across two prominent online databases SCOPUS and ERIC. As a result, we identified 48 studies published between 2011 and 2021, which are categorized into eight distinct themes: (1) the traditional laboratory and inquiry-based laboratory (IBL), (2) IBL implementation and curriculum, (3) types of IBL, (4) students’ perceptions of teaching assistants and benefits of IBL, (5) IBL to enhance skills and knowledge, (6) students’ attitude towards IBL, (7) the factors support student learning in IBL, (8) IBL to improve students’ autonomy and self-efficacy. Hence, it is suggested that future research focus more on applying IBL for General Physics Laboratory courses to improve physics teacher education students’ experimental competency.
