Thermodynamic constraints on a varying cosmological-constant-like term from the holographic equipartition law with a power-law corrected entropy

N Komatsu - Physical Review D, 2017 - APS
A power-law corrected entropy based on a quantum entanglement is considered to be a
viable black-hole entropy. In this study, as an alternative to Bekenstein-Hawking entropy, a …
