Possibility of Superconductivity of 6Li+ Ions in Solid Electrolytes at Room Temperature Under Coherent Acoustic Phonons

TL;DR

The paper explores how lithium ions in solid electrolytes might exhibit superconductivity at room temperature under specific acoustic conditions.

Contribution

It proposes a novel mechanism for room-temperature superconductivity involving 6Li+ ions and coherent acoustic phonons.

Findings

Coherent acoustic phonons may extend the de Broglie wavelength of Li ions beyond their atomic distance.

Quantum effects in Li ions could lead to superconductivity at room temperature.

Lower-frequency coherent phonons are more favorable for this phenomenon.

Abstract

It has been theoretically suggested that the de Broglie wavelength of Li ions could become longer than the Li atomic distance in solid electrolytes under coherent acoustic phonons at room temperature when thermal noise is sufficiently suppressed by them. This suggests that some quantum effect of Li ions (not electrons) could appear under this condition, which could possibly result in the superconductivity of 6Li+ ions (bosons) in solid electrolytes at room temperature. A lower frequency of coherent phonons is better for this possibility. A mechanism for the generation of coherent phonons by repetitive pulsed-laser irradiation or possibly by ultrasound irradiation using a transducer is also discussed.
