A Truncated Primordial Power Spectrum and its Impact on CMB Polarization
Jingwei Liu, Fulvio Melia
We investigate the impact of a hypothesized delayed initiation of inflation, characterized by a cutoff k_min to the primordial power spectrum in the cosmic microwave background (CM…
Challenges to Inflation in the Post-Planck Era
Jingwei Liu, Fulvio Melia
Space-based missions studying the cosmic microwave background (CMB) have progressively refined the parameter space in conventional models of inflation shortly ( seco…
A Truncated Primordial Power Spectrum and Its Impact on B-Mode Polarization
Jingwei Liu, Fulvio Melia
The absence of large-angle correlations in the temperature of the cosmic microwave background (CMB), confirmed by three independent satellite missions, creates significant tension…
Viability of slow-roll inflation in light of the non-zero k_min measured in the CMB power spectrum
Jingwei Liu, Fulvio Melia
Slow-roll inflation may simultaneously solve the horizon problem and generate a near scale-free fluctuation spectrum P(k). These two processes are intimately connected via the init…
