Abstract

Using simple box quantization, we demonstrate explicitly that a spatial transition will release or absorb energy, and that compactification releases latent heat with an attendant change in volume and entropy. Increasing spatial dimension for a given number of particles costs energy while decreasing dimensions supplies energy, which can be quantified, using a generalized version of the Clausius-Clapyeron relation. We show this explicitly for massive particles trapped in a box. Compactification from N -dimensional space to (N - 1) spatial dimensions is also simply demonstrated and the correct limit to achieve a lower energy result is to take the limit, Lw → 0, where Lw is the compactification length parameter. Higher dimensional space has more energy and more entropy, all other things being equal, for a given cutoff in energy.

Highlights

  • We demonstrate explicitly that a spatial transition will release or absorb energy, and that compactification releases latent heat with an attendant change in volume and entropy

  • Compactification is an old idea [1] [2] where one reduces the dimension of space to account for observed symmetries and conservation laws

  • We focus on box quantization and specialize to massive particles, such as electrons

Summary

Introduction

Compactification is an old idea [1] [2] where one reduces the dimension of space to account for observed symmetries and conservation laws. We demonstrate explicitly that a spatial transition will release or absorb energy, and that compactification releases latent heat with an attendant change in volume and entropy. We start by considering the energy levels of a massive particle trapped in a box or lattice in N = 3 versus ( N −1) =2 dimensional space.
