Constraints on R-n gravity from precession of orbits of S2-like stars: A case of a bulk distribution of mass
(Advances in Space Research, 2014)
Here we investigate possible applications of observed stellar orbits around Galactic Center for constraining the R-n gravity at Galactic scales. For that purpose, we simulated orbits of S2-like stars around the massive ...
Compact discrete breathers on flat-band networks
(Low Temperature Physics, 2018)
Linear wave equations on flat-band networks host compact localized eigenstates (CLS). Nonlinear wave equations on translationally invariant flat-band networks can host compact discrete breathers-time-periodic and spatially ...
