Abstract (AI)
In everyday life, if sound propagates from one location to another, it can propagate backwards just as easily. However, theorists show that it is possible to harness the radiation pressure interaction between light and matter to produce unidirectional sound propagation.
Key Findings
1
Radiation pressure interaction between light and matter can be harnessed to produce unidirectional (nonreciprocal) sound propagation.
2
The work establishes a mechanism linking optical control (light-matter radiation pressure) to topological phases in acoustic systems enabling directionally biased sound transport.
3
Theoretical analysis demonstrates that sound, which normally propagates equally forward and backward, can be made to propagate only in one direction using optomechanical interactions.
