Washington University in St. Louis has achieved a groundbreaking scientific milestone by creating a “time quasicrystal,” an entirely new phase of matter that redefines our understanding of time and motion.
In essence, a time crystal is a regular crystal that repeats patterns in space but also ticks in a consistent rhythm over time, combining three dimensions with the fourth dimension. The WashU team has built upon existing research on time crystals by creating a “time quasicrystal” that produces multiple frequencies instead of one predictable rhythm.
To achieve this, the team grew their time quasicrystals inside diamonds by removing tiny carbon atoms and allowing electrons to settle in those spaces. They then used microwave pulses to start its rhythmic ticking, which organized the vibrations in time.
The creation of a time quasicrystal has significant implications for quantum mechanics and potential practical applications. It could lead to more precise timekeeping, replacing traditional quartz oscillators with a more consistent and energy-efficient alternative. Additionally, it might power next-generation quantum sensors and computers by storing quantum memory over long periods of time.
“This is a crucial first step towards harnessing the power of time crystals for quantum computers,” said Chong Zu, an assistant professor of physics. “We’re far from that sort of technology, but creating a time quasicrystal is essential.”
