The Time Crystal survived an amazing 40 minutes

A team of physicists in Germany has created a time crystal that lasts 40 minutes, which is 10 million times longer than other known crystals, and can last even longer.

Ordinary crystals, by which I mean crystals found in large scale space, are solids whose atoms are arranged in a highly ordered pattern. Diamonds, snowflakes, and table salts are all crystalline. Time crystals are structures whose lowest energy states have highly ordered (periodic) patterns in space And time. It is also expected that the properties of time crystals will change suddenly at a given time, even without some external factor causing such a change.

In this way, time crystals break time translation symmetry, which is the idea that a piece of stable matter will not change (without external factors) if you drag it to a different point in time. Time crystals change based on a metaphysical whim, no matter when it happens. You can Read all about time crystals hereto better understand what it is and why it is useful.

A recent team of physicists has managed to create a time crystal that lasts an extremely long time: 40 minutes. Crystal is made of Indium gallium arsenide, or a mixture of indium atoms and gallium arsenide, is a semiconductor. It was their research published Last week in physical physics.

Firstly Proposed in 2012Time crystals have been manufactured in laboratory settings ever since. a Continuous time crystal has been reported In Bose-Einstein condensates, a type of supercooled material that operates in a quantum state, by a team of physicists in June 2022. But that time crystal only lasted a few milliseconds. Once again: The last crystal lasted for 40 minutes, and the team believes it could live even longer.

The new time crystal is located in the nuclear electron spin system. The team excited the material with polarized laser light, which polarized the spin of the nucleus in the system. This caused the indium gallium arsenide to produce oscillations, making it “equivalent to a time crystal,” according to TU Dortmund. launch.

“Based on these results, we can imagine this type of device becoming a compact and highly flexible on-chip frequency standard,” the team wrote in their paper.

The Time Crystal wasn’t perfect. There were parts of the material that the team said were “dissolving” or losing their special properties that would make it a time crystal. Although the time crystal lasted for 40 minutes, the researchers said they “can safely conclude that the lifetime of the TC is at least a few hours, and possibly longer.”

In other words, there’s a lot of physics where this came from, so buckle up your quantum seatbelt.
