Cosmic variance and ergodicity in finite systems with correlations
Dipayan Mukherjee, Syksy Rasanen
We consider the difference between ensemble and volume average in cosmology. It is known that for sufficiently weak long-range correlations the root mean square of the difference,…

Scalar-induced gravitational waves from coherent initial states
Dipayan Mukherjee, H. V. Ragavendra, Shiv K. Sethi
We investigate the impact of statistical inhomogeneity and anisotropy in primordial scalar perturbations on the scalar-induced gravitational waves (SIGW). Assuming inflationary qua…

Cosmological consequences of statistical inhomogeneity
H. V. Ragavendra, Dipayan Mukherjee, Shiv K. Sethi
A space-dependent mean for cosmological perturbations negates the ansatz of statistical homogeneity and isotropy, and hence ergodicity. In this work, we construct such a primordial…
