This study explores a dark matter model in which a pseudo-Nambu-Goldstone boson arises as a viable dark matter candidate from the spontaneous and soft breaking of global $\mathrm U(1)$ symmetries and stabilized by a residual $\mathbb{Z}_3$ discrete symmetry. The model introduces three complex scalar …

All possible theories of quantum gravity suggest the existence of a minimal length. As a consequence, the usual Heisenberg uncertainty principle (HUP) is replaced by a more general uncertainty principle known as the generalized uncertainty principle (GUP). The dynamics of all quantum mechanical …

This thesis explores quantum gravity-induced modifications via the generalized uncertainty principle (GUP), affecting energy levels in various systems and constraining the GUP parameter.

This study was conducted in a 1100 square kilometer area between the Beki and Manas Rivers, extending from the railway line in the north to the Brahmaputra River in the south. Three bat species were identified: Indian Fruit Bat, Leaf-Nosed Bat, and Chungabaduli.
