Research Summary

My research centers on theoretical and computational physics, specifically within the realm of materials science and condensed matter physics. A significant portion of my work examines the properties and applications of multi-functional devices in van der Waals homojunctions, alongside the intricate phase transitions and competing polar and nonpolar distortions in low-dimensional materials.

In my projects, I employ advanced computational techniques to model and analyze material properties, aiming to uncover novel functionalities and applications. This includes comprehensive studies on ferroelectricity, topological polarization, and multiferroic order in van der Waals materials. Additionally, I have developed minimal models to investigate the low-energy bands in twisted bilayer graphene, contributing to a deeper understanding of these complex systems.

Through my research, I strive to enhance the fundamental understanding of material behaviors under various conditions, which can pave the way for technological advancements and innovation in materials science.

In Plain English

My research focuses on understanding and developing new materials that have special properties, which can be used in advanced technology. I study materials that are made up of very thin layers, just a few atoms thick, and explore how they change and interact with each other.

One of my key areas of interest is creating devices out of these thin materials that can perform multiple functions, improving things like electronics and sensors. I also look into how these materials can change shape or properties under certain conditions, which can make them useful in innovative ways.

To do this, I use powerful computer simulations to predict how these materials will behave. This helps us design new materials with desired properties without having to make them physically first, saving time and resources.

Overall, my goal is to discover new ways these advanced materials can be used to improve technology, from more efficient electronics to new types of sensors and beyond.
