Measurements are presented for the low-energy positron annihilation spectra of the alkane molecules propane through octane. The downshift of the vibrational Feshbach resonances of the infrared-active C-H stretch vibrational modes is used to obtain updated values for the positron-molecule binding energies for these molecules. These binding energies correct previously reported values which had systematic energy shifts due to several small, but significant, errors in the analyses. Once these energy shifts are corrected, the old and new measured spectra are in good agreement. This updated analysis procedure is applied to other previously measured alkanes, providing updated binding energies for these molecules. The resulting data are shown to be in good agreement with a recent model-potential calculation and solve issues regarding the interpretation of previous measurements.

Unidirectional photon emission is crucial for constructing quantum networks and realizing scalable quantum information processing. In the present work an efficient scheme is developed for the unidirectional emission of a tunable squeezed microwave field. Our scheme is based on a chiral cavity magnonic system, where a magnon mode in a single-crystalline yttrium iron garnet (YIG) sphere is selectively coupled to one of the two degenerate rotating microwave modes in a torus-shaped cavity with the same chirality. With the YIG sphere driven by a two-color Floquet field to induce sidebands in the magnon-photon coupling, we show that the unidirectional emission of a tunable squeezed microwave field can be generated via the assistance of the dissipative magnon mode and a waveguide. Moreover, the direction of the proposed one-way emitter can be controlled on demand by reversing the biased magnetic field. Our work opens up an avenue to create and manipulate one-way nonclassical microwave radiation field and could find potential quantum technological applications.
