Physicists are proposing to cool microparticles with sound waves , At present, most quantum experiments are carried out with light, even in nanomechanics, where small objects are cooled by electromagnetic waves in such a way that they have quantum properties.

A team of physicists is now proposing to cool micro particles with sound waves.

While quantum physics usually deals with the basic blocks of light and matter, scientists have been trying to study the quantum properties of larger objects for some time.

This is how the boundary between the quantum world and everyday life is explored.

For this purpose, particles are delayed by electromagnetic waves and motor energy is drastically reduced. Because of that people talk about “mobile cooling”. Physicists are proposing to cool microparticles with sound waves .

Quantum properties occur when particles are cooled to a basic quantum ground state, which is to the lowest possible energy level.

So far, the only way to cool a particle to its basic state is by interacting with photons trapped in an electromagnetic resonator.

Similar to photons, quantum vibrations of light in solids can be called phonons. This small sound wave packet spreads through a solid crystal lattice.

The phone is very isolated and only interacts with the movement of particles through magnetic waves, researchers explained. In our work, we now show that this interaction can be controlled by magnetic fields. Physicists are proposing to cool microparticles with sound waves .

This allows quantum experiments to be carried out without photons and thus also with light absorbing particles.

Researchers say: On the contrary, we also show that the strong interaction between motion and phonons provides a way to explore and manipulate the dynamics of acoustic and magnetic waves that are subtle and exotic in very small particles, researchers say.

This new method also opens up new possibilities for processing quantum information, for example by using phonons as quantum memory.
