Description
This study delves into modified f(Q,B) gravity, with a primary emphasis on solving field equations within the FLRW metric framework. It investigates bouncing scenarios by scrutinizing two nonlinear cosmological models and assesses energy conditions to authenticate bouncing cosmologies as viable alternatives to the conventional Big Bang theory. Furthermore, this analysis extends to examining geometrical parameters to shed light on the accelerating universe, providing significant insights into the implications of modified gravity for our comprehension of cosmic evolution. In addition, a perturbative analysis is performed for both models, showing that a nearly scale-invariant scalar spectral index ns and a suppressed tensor-to-scalar ratio r can be achieved for suitable parameter ranges, thus supporting the observational viability of the proposed bouncing framework. 2025 World Scientific Publishing Company.
