Zero point Energy/ zero point fields are not the new issue in the arena of physics but we feel new. Here, I am not going to set up a model to calculate zero point energy in particular case but collect some ideas and give definition of zero point energy, based on earlier brief attempts and present two ways of getting zero point energy in nature and some calculated result of zero point energy in some special cases. These things provide some ideas about zero point energy and substantiate the entity of zero point fluctuations and zero point energy in vacuum even at absolute zero.

Detailed Application

Criteria are established for the definition of the mean characteristic eigenvalue, λ0, of a system of coupled harmonic oscillators. The first criterion is that λ0 lead to a convergent series for the zero point energy of the systems; the second criterion is that λ0 be obtained directly from the matrix elements of the equations of motion, without solution for the individual eigenvalues. Two general types of λ0's are found and their properties are discussed. Detailed application is made to the zero point energy differences of the isotopic methanes, ethylenes and benzenes.

Definition Of

This paper starts with the most basic concept of heat as well as temperature, historically investigates the understanding of the nature of heat, the conclusion is that the nature of heat is just a form of energy. This energy includes the zero-point energy providing by the motion of all subatomic particles. The new definition of temperature should be that it is the degree of matter’s motion. These matters include subatomic particles. Therefore, at the absolute zero, the “temperature” should still exist. On accounting of no subatomic particles’ motion in the singularity of the black hole, I proved that there exists a new absolute zero temperature there, which is lower than the existing one. The theory proposed in this paper can be supported by following means: measuring the temperature inside the black hole, letting electrons stop moving, and designing a Casimir vacuum pump.

State Of Rest

In the present paper we shall attempt to collate the results of four separate lines of research which, taken together, appear to provide some interesting checks between theory and experiment. The investigations to be considered are (1) the discussion by Waller* and by Wentzel,† on the basis of the quantum (wave) mechanics, of the scattering of radiation by an atom ; (2) the calculation by Hartree of the Schrödinger distribution of charge in the atoms of chlorine and sodium ; (3) the measurements of James and Miss Firth‡ of the scattering power of the sodium and chlorine atoms in the rock-salt crystal for X-rays at a series of temperatures extending as low as the temperature of liquid air ; and (4) the theoretical discussion of the temperature factor of X-ray reflexion by Debye§ and by Waller.∥ Application of the laws of scattering to the distribution of charge calculated for the sodium and chlorine atoms, enables us to calculate the coherent atomic scattering for X-radiation, as a function of the angle of scattering and of the wave-length, for these atoms in a state of rest, assuming that the frequency of the X-radiation is higher than, and not too near the frequency of the K - absorption edge for the atom.¶ From the observed scattering power at the temperature of liquid air, and from the measured value of the temperature factor, we can, by applying the theory of the temperature effect, calculate the scattering power at the absolute zero, or rather for the atom reduced to a state of rest. The extrapolation to a state of rest will differ according to whether we assume the existence or absence of zero point energy in the crystal lattice. Hence we may hope, in the first place to test the agreement between the observed scattering power and that calculated from the atomic model, and in the second place to see whether the experimental results indicate the presence of zero-point energy or no.
