The main results are related to the spin-free theory of spin properties. In particular, the theorem previously stated (Luzanov and Whyman, Int J Quantum Chem, 1981, 20, 1179) is refined by an explicit general representation of spin density operators through spin-free (charge) RDMs. Some ...
Spin is a common phrase often used in various branches of physics, such as atomic physics and nuclear physics. According to nuclear physics, spin is always referred to as nuclear spin.Answer and Explanation: The spin is also referred to as the intrinsic total angular momentum of a certain ...

To create entangled particles you essentially break a system into two, where the sum of the parts is known. For example, you can split a particle with spin of zero into two particles that necessarily will have opposite spins so that their sum is zero. In 1935, Albert Einstein, Bori...
Our instruments went out for a spin when researchers at the University of Texas loaded up the back of a hatchback for a study of the physiological effects of air pollution. The study was published in 2022 in the journal Sensors. Included were three instruments from 2B Tech to measure O3, ...
What I want to draw attention to here is the way in which spin, although spanning a much shorter time frame, suffers from some analogous confusions; confusions that arise partly because of its connection with different theories (relativity and quantum mechanics) but also because of interpretive ...
I cringe a little at how simple this work is, but there’s still great value in observation and a “data paper” as I regarded this one. Still, I like it and it fills a lacuna in our understanding, and takes my research a step further toward what I’d like to know (e.g., what...
This is the recipe: present only one guest that represents your narrative; allow the moderator to frame the discourse to fit that bias and never question the narrative; go so off theme of the actual topic that the talk is supposed to cover (in this case “On Western Media and Syria”);...
My group is now Dr. Vivian Allen as the postdoc, Sophie Regnault as the PhD student, and Kyle Chadwick as the technician and MRes student, along with numerous collaborators and spin-off projects. We’re looking forward to sharing more! But for now, I hope that I’ve engendered some ...
