Electronic Response To Nuclear Breathing Node | |||||
| Coauthors | ||||||||

Abstract |
I will derive the equations that govern the pulsation of electron gas around giant nuclei, present spectrum and stationary modes where possible as analytic expressions and numerically otherwise. Then I apply these results to investigate the general dynamics of the system using the spectral method, focussing on a harmonic driving force exerted on the electron gas by the breathing mode of the underlying nucleus. |

Title |
$f(R,\mathcal{L}_m)$ Gravity With Pressuron Mechanism | |||||
| Coauthors | ||||||||
|
Abstract |
There is a well established equivalence of minimally coupled scalar-tensor theories and $f(R)$ theories. In this talk I will present an unusual $f(R,\mathcal{L}_m)$ Lagrangian that is equivalent to the $\omega\rightarrow 0$ limit of pressuron theories, a class of non minimally coupled scalar-tensor theories designed to reproduce general relativity under the low pressure conditions found in the solar system. I will also briefly discuss the Lagrangian formalism for perfect fluids in curved space-time and give an outlook of exact cosmological solutions in this theory. |
