APS Focus: Vibrations and Electrons Team Up in New Quantum Entity

November 28th, 2011  |  by  |  published in All, Blog, Press

Theorists propose an experiment to observe a “phoniton,” a novel hybrid of an electron and a quantum of vibration in a crystal lattice.

Vibrations in a crystal can combine with an electron in a new way to form a hybrid quantum entity, according to a team of theorists publishing in Physical Review Letters. They call it a “phoniton,” a particle that combines a phonon—the quantum form of vibrations—with a matter excitation, such as an electron that transits between two levels. The team also proposes a nanostructure that would support this quantum state and allow it to be observed.

Introducing the phoniton: A sound-based analogue of cavity-QED, a tool for controlling sound at the quantum level

This work explores the possibility of a new, man-made quantum object: a hybridization of a localized, long-lived phonon (a quantum of sound) and a matter excitation. That this is possible is not obvious.
