Cosmological bounces in spatially flat FRW spacetimes in metric f(R) gravity
TL;DR: In this paper, an interesting method to analyze the bouncing FRW solutions in a spatially flat universe using f(R) gravity models using an effective Einstein frame description of the process is presented.

An Effective Hamiltonian Approach to Quantum Random Walk
TL;DR: Chandrashekar et al. as discussed by the authors presented an effective Hamiltonian approach for discrete time quantum random walk, which can be written as the sum of a Weyl Hamiltonian and a Dirac comb potential.

Global analysis of luminosity- and colour-dependent galaxy clustering in the Sloan Digital Sky Survey
TL;DR: In this paper, the authors presented a Halo Occupation Distribution (HOD) analysis of the luminosity and colour-dependent galaxy clustering in the Sloan Digital Sky Survey (SDSS) using a combination of clustering measurements in luminosity bins to perform a global likelihood analysis.

Constraining the dark energy statefinder hierarchy in a kinematic approach.
TL;DR: In this paper, a Markov chain Monte Carlo analysis has been carried out using the observational measurements of Hubble parameter at different redshifts, the distance modulus data of type Ia supernovae and baryon acoustic oscillation data to estimate the coefficient of series expansion of the Hubble parameter.
