Furthermore, GPT-4’s natural language processing capabilities simplify the programming process, making it more accessible for a wider audience to contribute to the project’s development. Individuals without prior experience in interface development can swiftly create projects by providing GPT-4 with plain-language instructions.

Throughout this project, we will walk you through the process of utilizing GPT-4 technology to generate code for interactive physics system simulations, offering you the opportunity to delve into the fascinating world of physics and complex systems. Let’s embark on this thrilling journey of exploration together!

XY Model

The XY model originates from condensed matter physics and mainly studies a particle system on a two-dimensional plane. These particles can be imagined as compasses, distributed on the plane, and each particle has a direction. The core of this model lies in the interaction between particles: each particle tends to maintain the same direction as neighboring particles. This interaction forms an interesting balance, where particles strive to maintain consistency while responding to the influence of other particles.

In the XY model, we can observe a fascinating emergent phenomenon: when the interaction between particles reaches a certain degree, the entire system will spontaneously form an ordered state, and the particles will point in roughly the same direction. This ordered state reflects the self-organizing behavior inside the system and is a typical phenomenon in complex systems.

The XY model also contains a very interesting and important physical phenomenon - the Berezinskii–Kosterlitz–Thouless (BKT) phase transition. The discovery of the KT phase transition brought revolutionary breakthroughs to the theory of phase transitions, and even led to the Nobel Prize in Physics being awarded to physicists Kosterlitz and Thouless in 2016.

Unlike the first- and second-order phase transitions we are familiar with, such as water turning into ice or water vapor, the KT phase transition is a topological phase transition. This means that it does not involve a sudden change in the density, magnetism, or other physical properties of matter, but rather involves a change in the internal topological structure of the system. In the XY model, this topological structure is manifested as vortices and antivortices, which can be understood as local rotational structures with different rotation directions.

When the temperature is low, vortices and antivortices form a stable paired state, and their mutual attraction makes the system present an ordered state. However, when the temperature rises to a critical point, vortices and antivortices begin to dissociate, and the degree of order in the system gradually decreases. This is the process described by the KT phase transition.

Through the XY model in the online interactive physics system simulation project, we can intuitively observe the process of the KT phase transition and understand how this unique topological phase transition occurs in complex systems. This is undoubtedly an attractive learning path for science enthusiasts who want to deepen their understanding of phase transitions, topological structures, and emergent phenomena.

Phase Separation

Phase separation is a widely existing phenomenon in nature, which refers to the spontaneous separation of different types of components into regions of a single component in a mixed system under certain conditions. This process is involved in many chemical, physical, and biological systems, such as oil-water mixtures, cooling and separation of alloys, and distribution of lipid molecules on cell membranes.

The concept closely related to phase separation is pattern formation, which describes the self-organizing phenomenon of spatial structure under certain conditions. This phenomenon is often accompanied by the appearance of local structure and order. In the process of phase separation, we can observe a series of complex pattern formation phenomena, such as bubble-like structures, stripe-like structures, etc. These patterns can be understood as stable structures formed by the system in the process of trying to reduce energy.

In the online interactive physics system simulation project, the phase separation model uses a simplified two-dimensional particle system to simulate the phase separation phenomenon. Although this model is simplified, it can intuitively demonstrate the basic mechanisms of phase separation, such as like attraction, unlike repulsion, and random motion between particles.

Physics Visualization Platform

In this ChatGPT-assisted project website, we strive to present an engaging and educational online physics visualization platform. Through this platform, users can personally interact with a variety of physical phenomena and complex systems, gaining a more intuitive and vivid understanding of the principles underlying these phenomena.

Our project website features multiple physics simulation examples generated by GPT-4, such as the Vicsek model, the XY model, and the phase separation model. These models are designed to help users comprehend the operational principles and emergent phenomena of complex systems. Additionally, the website offers a series of mouse-interactive models, enabling users to experience the allure of physical phenomena through real-time interaction.

Coding with GPT-4

To conclude this article, let’s discuss how this project was brought to life through ChatGPT. In implementing the phase separation project, I didn’t specify any particular model. Instead, I provided the following requirements:

• Implement a visual phase separation model using HTML.
• Add repulsion to the model to prevent particle aggregation.
• Handle boundary conditions.
• Introduce temperature as a parameter.
• Add sliders to control all parameters.

Based on these requirements, ChatGPT generated the corresponding HTML and JavaScript code, creating an interactive physics simulation project (there were five or six conversations from the initial command to the generation of a functional model that could display phenomena, followed by more detailed discussions with ChatGPT to refine the page’s appearance). Throughout this process, GPT-4 exhibited an incredible ability to understand my project’s core objectives based on my requirements and generate the appropriate code to fulfill them. It is worth noting, however, that there is a limit to the length of code output by ChatGPT. If the output is interrupted, you can copy and paste the end of the output code and ask GPT to continue writing, ensuring a seamless code-writing process.

Although I’m not well-versed in JavaScript syntax details, I was able to understand how specific calculations were implemented in the physics portion by examining the code (as a pseudo-code reader), which allowed me to verify its accuracy. Overall, correctness checks still require some coding experience, but developers don’t need to know every syntax detail.

For the interface layer, the logic is visually apparent, so it can also be checked. If errors are detected, feedback can be given directly, and GPT-4 possesses a robust self-checking capability.

In collaboration with ChatGPT, we have successfully developed a fun and practical online interactive physics system simulation project. This project not only enables us to grasp complex physical phenomena intuitively but also showcases GPT-4’s enormous potential in code generation and project implementation. Furthermore, GPT-4’s powerful features have saved significant time and effort during the development process, making it possible for physicists and novices alike to swiftly create high-quality visualization and interactive projects.

In conclusion, while GPT-4 cannot currently replace all human work, it can significantly streamline the development process and empower beginners to accomplish tasks that were previously unattainable. In the future, we eagerly anticipate deeper collaboration with artificial intelligence technologies like GPT-4 to explore more innovative applications and solutions.
