Semiconductor time crystals synchronize oscillations across distances, researchers report
Multiple time crystals can lock frequencies across 40 micrometers, according to ScienceDaily.
The short version
- Researchers at TU Dortmund University demonstrated that separate time crystals inside a semiconductor can synchronize their electron-nuclear spin oscillations.[ScienceDaily]
- The coupling is driven by spin-polarized electrons across distances up to 40 micrometers, more than 1,000 times the size of an individual oscillator.[ScienceDaily]
- Beyond that separation threshold, the time crystals cease locking together and continue oscillating independently.[ScienceDaily]
- The team noted the mechanism could aid in developing future networks of controllable spin oscillators.[ScienceDaily]
Key facts
- Physicists at TU Dortmund University led by Alex Greilich published findings showing multiple time crystals can synchronize their oscillations inside a semiconductor.[ScienceDaily]
- The experimental material is a semiconductor made of gallium arsenide doped with indium and silicon, operated near -270 °C.[ScienceDaily]
- The coupling relies on moving spin-polarized electrons rather than mechanical vibration.[ScienceDaily]
- The synchronization persists over distances up to 40 micrometers, which is over 1,000 times the characteristic size of an oscillator.[ScienceDaily]
What remains uncertain
- The synchronization effect ceases at distances exceeding 40 micrometers, causing the oscillators to decouple.[ScienceDaily]
- Practical applications for networks of controllable spin oscillators and spin-based technology remain prospective.[ScienceDaily]
