We publish essentially in the so-called "scientific literature", which is an unending flow of new results, with daily deliveries. This is the kind of things that is tougher to read than to write.
The correct abbreviation for a journal is ruled by the ISO 4. For instance, the "IEEE Transactions on Sonics and Ultrasonics" gets abbreviated to "IEEE Trans. Sonics Ultrason."  (that's the journal where was published the 1st experimental demonstration of X waves).
To us, this is the most significant Physics journal. It is not the most prestigious one in terms of impact factor, but this is due to the very high volume processed as compared to journals from the Nature family that are so restrictive as to be biased and biasing, as well as, ultimately, not even serving that well the coverage of the progress of science, which is better reflected in Phys. Rev. Lett.. The journal is affectionately known as PRL.
The open-access, online-only journal in all fields of Physics, published by the IOP. It comes with video abstracts if the authors are so inclined. It is from the DPG and charges a publication fee. It has a nice Focus On series.
Last but not least, the arXiv.
