Humans experience the world in three dimensions, but a collaboration in Japan has developed a way to create synthetic dimensions to better understand the fundamental laws of the Universe and possibly apply them to advanced technologies.
They published their results on January 28, 2022 in Science Advances.
“The concept of dimensionality has become a central fixture in diverse fields of contemporary physics and technology in past years,” said paper author Toshihiko Baba, professor in the Department of Electrical and Computer Engineering, Yokohama National University. “While inquiries into lower-dimensional materials and structures have been fruitful, rapid advances in topology have uncovered a further abundance of potentially useful phenomena depending on the dimensionality of the system, even going beyond the three spatial dimensions available in the world around us.”
Topology refers to an extension of geometry that mathematically describes spaces with properties preserved in continuous distortion, such as the twist of a mobius strip. When combined with light, according to Baba, these physical spaces can be directed in a way that allows researchers to induce highly complicated phenomena.
