Researchers at the University of Missouri have achieved a significant breakthrough by creating a synthetic 4D metamaterial capable of controlling energy waves on solid surfaces. This metamaterial adds a new level of control to what is known as the “fourth dimension” or synthetic dimension, which extends beyond our familiar 3D physical reality. By directing mechanical waves along specific paths on solid materials, this innovative material opens up possibilities for advancements in quantum mechanics, quantum computing, and earthquake mitigation.
The new synthetic metamaterial allows for the manipulation of energy wave paths in the synthetic dimension, going beyond the conventional three-dimensional limits along the X, Y, and Z axes. The breakthrough, known as “topological pumping,” may have implications in quantum mechanics and quantum computing due to the development of higher-dimensional quantum-mechanical effects.
Furthermore, this material could find practical applications in earthquake mitigation. By covering a structure’s surface with the synthetic metamaterial and placing it underneath buildings, it could potentially prevent collapse during earthquakes by controlling the energy waves that propagate along the Earth’s surface.
The research builds upon earlier work by the team, where they demonstrated the ability of a passive metamaterial to control the path of sound waves within materials. While the discovery is currently a foundational building block, it holds promise for various fields, including civil engineering, micro-electromechanical systems (MEMS), and national defense.
The study was published in the journal Science Advances and received support from grants provided by the Air Force Office of Scientific Research and the Army Research Office.
