In summary, time crystals are a state of matter that exhibit periodic motion in their ground state, defying traditional thermodynamic laws. They require energy to be continuously added to maintain their oscillations, distinguishing them from ordinary crystals. This unique characteristic allows time crystals to exist in a nonequilibrium state, leading to potential applications in quantum computing and other advanced technologies.

I was initially under the impression that time crystals are in lowest energy state and neither gain or lose energy. But other sources suggested they might require a bump in energy after a while to keep going?

What are "time crystals" ?
It takes energy to get a crystal oscillating.
Depending on how they are mounted, crystals can oscillate with a very high efficiency.
That oscillation can be maintained with very little added energy.

Time crystals. Not that I know the answer to the question, but I do know how to google :wink:

The wikipedia page linked by Filip says, in the introductory paragraph, that time crystals have been realized in periodically driven systems. I don't know where OP gets "bump in energy," but if it takes periodic driving to create a time crystal, then energy is at least being used to maintain the driving system.

The OP has a history of poorly sourced/referenced posts. In this case,

Are of course impossible to follow up on.

The OP in this case is so badly presented that I can't tell if he's really talking about "time crystals" or "crystals in an oscillator used to measure time."

The question cannot be important. Since that posting, the OP has not logged back in.

It seems the answer is both yes and no, and no and yes, depending on the application of, and the meaning of time crystal.

The OP has a history of starting threads and not participating.

Looks like he fooled us again.

Yes, this is the time crystal I am referring to. And the only reference I can offer to needing to add energy to the system is from a YouTube video which I'm told isn't a good source, so I didn't include it.

So you knew that your source was unreliable, tried to hide it and post anyway?

Why don't you find a reliable source? Then we can discuss it intelligently.

In other words, you don't have a valid reference as a basis for discussion. Thread closed.
 

FAQ: Time crystals: They require energy added back into them?

What are time crystals?

Time crystals are a state of matter where the system exhibits periodic structure in time, rather than in space. Unlike traditional crystals that have repeating patterns in three-dimensional space, time crystals have a pattern that repeats in time, even in their ground state.

Why do time crystals require energy to be added back into them?

Time crystals require energy to be added back into them to maintain their periodic motion. This is because they exist in a non-equilibrium state, and without external energy input, they would eventually settle into a conventional equilibrium state, losing their time-crystalline properties.

How is energy typically added to time crystals?

Energy is typically added to time crystals through periodic driving, such as applying a series of laser pulses or electromagnetic fields. This external driving force helps to sustain the repeating temporal pattern, preventing the system from reaching thermal equilibrium.

Can time crystals exist at absolute zero temperature?

No, time crystals cannot exist at absolute zero temperature. They require some form of external energy input to maintain their time-periodic structure. At absolute zero, there would be no energy available to sustain the periodic motion, causing the time crystal to lose its unique properties.

What potential applications do time crystals have?

Potential applications of time crystals include advancements in quantum computing, where they could be used to create more stable qubits, and in precision measurement technologies. Their unique properties might also lead to new ways of storing and transferring energy or information.
