Abstract

We present a bounce universe in modified f(Q,C) gravity considering linear as well as exponential form of gravity. Bounce cosmological models are introduced to remove the singularity problem of the early universe. A new quadratic boundary term (C²), which is added in the modified gravity to study different features of the universe in the framework of bouncing cosmology. Both power law expansion and exponential emergent universe are explored in linear modified gravity. The energy conditions and stability of cosmological bounce are investigated. We also compared power law expansion in linear and exponential form of modified gravity.
