Numerical modeling of the multi-stage Stern$unicode{x2013}$Gerlach experiment by Frisch and Segrè using co-quantum dynamics via the Bloch equation

Posted by klaurent Caltech

Kavli Affiliate: Lihong V. Wang | First 5 Authors: Kelvin Titimbo, David C. Garrett, S. Suleyman Kahraman, Zhe He, Lihong V. Wang | Summary: We numerically study the spin flip in the Frisch$unicode{x2013}$Segr`e experiment, the first multi-stage Stern$unicode{x2013}$Gerlach experiment, within the context of the novel co-quantum dynamics theory. We model the middle stage responsible for […]

Uncovering dark matter density profiles in dwarf galaxies with graph neural networks

Posted by klaurent MIT

Kavli Affiliate: Lina Necib | First 5 Authors: Tri Nguyen, Siddharth Mishra-Sharma, Reuel Williams, Lina Necib, | Summary: Dwarf galaxies are small, dark matter-dominated galaxies, some of which are embedded within the Milky Way. Their lack of baryonic matter (e.g., stars and gas) makes them perfect test beds for probing the properties of dark matter […]

On the formation of over-ionized plasma in evolved supernova remnants

Posted by klaurent Tokyo

Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Miho Katsuragawa, Shiu-Hang Lee, Hirokazu Odaka, Aya Bamba, Hideaki Matsumura | Summary: One of the outstanding mysteries surrounding the rich diversity found in supernova remnants (SNRs) is the recent discovery of over-ionized or recombining plasma from a number of dynamically evolved objects. To help decipher its formation […]
