Differential geometry of collective models
AIMS Mathematics, 2019 The classical astrophysical theory of Riemann ellipsoids and the quantum nuclear theory of Bohr and Mottelson share a common mathematical foundation in terms of the differential geometry of a principal bundle ${\cal P}$ and its associated vector bundle E,

Stellar Physics and General Relativity
Astronomische Nachrichten, EarlyView.ABSTRACT The general theory of relativity is currently established as the most precise theory of gravity supported by observations, and its application is diverse ranging from astronomy to cosmology, while its application to astrophysics has been restricted only to compact stars due to the assumption that the Newtonian approximation is sufficient for ...

High energy neutrino astrophysics [PDF]
, 1998 I give a brief discussion of possible sources of high energy neutrinos of astrophysical origin over the energy range from $\sim 10^{12}$ eV to $\sim 10^{25}$ eV. In particular I shall review predictions of the diffuse neutrino intensity.

Phenomenology, astrophysics and cosmology of theories with submillimeter dimensions and TeV scale quantum gravity [PDF]
, 1998 We recently proposed a solution to the hierarchy problem not relying on low-energy supersymmetry or technicolor. Instead, the problem is nullified by bringing quantum gravity down to the TeV scale.

Experiment regarding magnetic fields with gravity
IET Quantum Communication, Volume 3, Issue 4, Page 218-228, December 2022., 2022 Abstract This experiment was designed to test the string theory as a physical reality. The ground‐based device placed the N poles of the magnets upwards, north, south, east, and west. Coil Ass'Y was placed between 2 N poles with bearing covers on the top and bottom.
