However, non-reciprocal forces can arise. Specifically, this has recently been shown theoretically in the interaction between dissimilar optically trapped particles mediated by an external field. As a result, despite the incident external field not having a transverse component of momentum, the particle pair experiences a force in a direction transverse to the light propagation direction. In this letter, we directly measure the net non-reciprocal force in elec","authors_text":"Curtis W. Peterson, Delphine Coursault, John Parker, Norbert F. Scherer, Stephen K. Gray, Stuart A.
