How can we jump to the next level in nuclear reactions models?

New short paper out 🧵

We are working on it since forever, but there's no microscopic model that can calculate the structure of the nucleus and its reactions @ MeV.

For example, see how the lines are above the experiments points? 👇

~100ks hours of computing and the nucleus is too "transparent".

New paper out📝!

Let’s explain how we take the impractical high energy-short range nuclear interactions or functionals out there and make up something that can be used for nuclei w. strange shapes🥔

Today @PhysRevC:
journals.aps.org/prc/abstract/1…
#nuclear #physics #paper The big problem in nuclear physics is that the nucleus is composed of many neutrons and protons, making it a quantum many-body system. Furthermore, the interaction between them is unknown and extremely complicated.

This kind of complicated 👇

*Twitter thread di sfogo*
Ho un bellissimo progetto di divulgazione da anni.
Abbiamo fatto ricerca, scritto articoli scientifici, aperto startup tecnologiche, discusso assieme delle bellezze della scienza.
In pochi mesi è stato martoriato da una invasione di barbari!

(1/19) Se volete unirvi il gruppo è t.me/scienza. E’ un gruppo piuttosto attivo, con tanti utenti, a cui fanno capo diverse iniziative di divulgazione che trovate su t.me/scienzanetwork fra cui ultimamente twitch.tv/meetscience che conoscete molto bene.

Let's start twitter threads by showing our paper on forbidden transitions in stars:
physics.aps.org/articles/v12/1…
@PhysRevLett

Intermediate mass stars are the most common in our galaxy, a very special nuclear transition will decide their fate.

(1/n, n=12) Low mass stars (m < 7*M☉, with M☉ = sun mass) death triggers a runaway thermonuclear explosion leaving a white dwarf remnant. High mass stars (m > 13*M☉) undergo a collapse of the core leaving a neutron star or a black hole behind. In the middle, we thought we knew.
