Gravitomagnetism is an ultra-weak effect of general relativity. Its direct detection is comparatively recent and based on analysis of the orbits of satellites around Earth. Indirect evidence may be found in the dynamics of the double pulsar system and other analogous systems. Other experiments exploiting ring lasers have been envisaged or are being implemented. It is worth seeing where we are on the side of experimental characterization of these effects. At the same time, there are e number of questions which should be posed and discussed. Is there a link between gravitomagnetic effects and dark matter in our galaxy and in the visible universe? What role has gravitomagnetism played during the early phases of the evolution of the universe?
The most puzzling question is, however, has gravitomagnetism anything to do with quantum mechanics? On the experimental side, it is interesting to investigate the role that could be played by macroscopic atomic systems. An example is the use of atomic or particle beams, occasionally envisaged in the past in Sagnac-like experiments. A fascinating opportunity could be the use of quantum fluids, such as helium liquids, or superconducting devices. On the conceptual side, we know that quantum mechanics is fully compatible with special relativity and conflicting with general relativity. What about gravitomagnetism? Its relevance may be fully negligible because of the smallness of the effects; however, the relevant aspect is what gravitomagnetism, when it is not a simple coordinate effect, has to do with space–time symmetries. Would this have a subtle influence on atomic systems? Formally exiting the domain of gravitomagnetism, we find another interesting possibility, fully compatible with general relativity and connected with symmetries: this is torsion.
As we can see, there are plenty of good reasons to discuss gravitomagnetism and quantum mechanics.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Entropy is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
