“…(Gupt and Singh, 2012;Gupt and Singh, 2013; and references therein.]. In particular, the last two approaches have been widely studied and found that they are all consistent with current cosmological observations (Agullo and Morris, 2015;de Blas and Olmedo, 2016;Castelló Gomar et al, 2017;Agullo et al, 2018;Elizaga Navascués et al, 2018;Navascues et al, 2018;Wu et al, 2018;Zhu et al, 2018). In addition, within the framework of the dressed metric approach recently it has been also shown that some anomalies from the CMB data (Akrami and Planck collaboration, 2020;Akrami and Planck collaboration, 2020;Schwarz et al, 2016) can be reconciled purely due to the quantum geometric effects (Ashtekar et al, 2020;Ashtekar et al, 2021).…”
