In a recent study published in Science Bulletin, researchers have demonstrated a new type of topological material using sound waves. This research, involving Dr. Emil Prodan from the Katz School's M.A. in Physics, opens up possibilities for future technologies.
Topological materials are distinct because their properties are governed by mathematical rules related to symmetry and topology. These materials can guide energy, charge, or sound along their edges without power loss, making them useful for developing robust devices like quantum computers.
The study focuses on "D-class topological phases," which are significant due to their potential to host Majorana particles. According to Dr. Prodan, "Majorana particles are fascinating because they behave like their own opposites—a rare trait in the particle world." He believes they could be used to build more stable quantum computers.
Previously, D-class phases were mostly theoretical and difficult to create experimentally, especially in two dimensions (2D). In this study, researchers created a topological material mimicking D-class phase behavior using sound waves. They constructed an acoustic crystal with tiny cavities connected mathematically to exhibit necessary symmetries for D-class phases.
Shi-Qiao Wu from Soochow University in China noted the significance of creating a 2D version of this phase using sound: “This is a big deal because it’s the first time anyone has managed to create a 2D version of this phase using sound.” The team observed that sound moved robustly along the material's edges as predicted.
The research suggests advancements toward quantum computing by creating materials supporting Majorana particles. These materials could enhance quantum information storage and processing. Additionally, techniques from this study may lead to breakthroughs in electronics and energy storage.
Researchers aim to explore creating "p-fluxes" for stabilizing Majorana particles further and utilizing these materials for information processing akin to computer chips.
Dr. Prodan commented on the progress: “While there’s still a long way to go, this research represents an important step forward.”
