• TITLE: Ground State Energy Density of the Quantum Harmonic Oscillator

  AUTHORS: Firmin J. Oliveira

  KEYWORDS: Planck Time, Quantum Harmonic Oscillator, Vacuum Energy Density, Cosmological Constant

  JOURNAL NAME: Journal of High Energy Physics, Gravitation and Cosmology, Vol.5 No.3, July 31, 2019

  ABSTRACT: The total energy of the ground state of the quantum harmonic oscillator is obtained with minimal assumptions. The vacuum energy density of the universe is derived and a cutoff frequency is obtained for the upper bound of the quantum harmonic oscillator.
