Soliton solutions
Researchers studying solitons at Ohio State University have found that the particles could one day be used in molecular electronics and artificial muscles.

Scientists have discovered something new about exotic particles called solitons. Since the 1980s, scientists have known that solitons can carry an electrical charge when travelling through certain organic polymers. A new study now suggests that solitons have intricate internal structures.
Scientists may one day use this information to put the particles to work in molecular electronics and artificial muscles, said Ju Li, assistant professor of materials science and engineering at Ohio State University.
Li explained that each soliton is made up of an electron surrounded by other particles called phonons. Just as a photon is a particle of light energy, a phonon is a particle of vibrational energy.
The new study suggests that the electron inside a soliton can attain different energy states, just like the electron in a hydrogen atom.
"While we know that such internal electronic structures exist in all atoms, this is the first time anyone has shown that such structures exist in a soliton," Li said.
