Abstract

Within the framework of loop quantum cosmology (LQC), we investigate the effect of inverse volume corrections on the low scale spontaneously broken supersymmetric (SB SUSY) and exponential inflationary potentials. The LQC modifications to the Friedmann equations and cosmological perturbation parameters are employed to assess the observational viability of these models against recent data from the Atacama Cosmology Telescope (ACT). Our results indicate that in contrast to the standard model of inflation, in the presence of inverse volume corrections in LQC, the predictions of SB SUSY and exponential potentials in the 𝑟 − 𝑛s plane lie inside the 68% confidence level interval of the ACT data.
