The paper referenced in this article could be drawing another duel between string theory and condensed matter physics. String theory phenomenology and quantum many–body systems Sergio Gutiérrez, Abel Camacho, Héctor Hernández arXiv:1707.07757 [gr-qc] <https://arxiv.org/abs/1707.07757> In the paper, the authors calculate how additional space-like dimensions affect a condensate of ultracold atoms, known as Bose-Einstein-Condensate. At such low temperatures, the atoms transition to a state where their quantum wave-function acts as one and the system begins to display quantum effects, such as interference, throughout. In the presence of extra-dimensions, every particle’s wave-function has higher harmonics because the extra-dimensions have to close up, in the simplest case like circles. The particle’s wave-functions have to fit into the extra dimensions, meaning their wave-length must be an integer fraction of the radius. It seems to me that all the conditions required to show the hidden dimensions expected by string theory are meet in condensed matter physics using the bosonic quasiparticle called the Surface Plasmon Polariton (SPP). This boson can form non-equilibrium Bose-Einstein condensates at room temperature and beyond. In “Oscillatory behavior of the specific heat at low temperature in quasiperiodic structures” E.L. Albuquerquea;*∗*, C.G. Bezerraa, P.W. Maurizb, M.S. Vasconcelos, a structure featuring 11 level discontinuity in specific heat as predicted by the Mexican paper is shown to exist. The behavior of a variety of particles or quasi-particles (electrons, phonons, photons, polaritons, magnons, etc.) has been and is currently being studied in quasi-periodic systems. A fascinating feature of these quasi-periodic structures is that they exhibit collective properties not shared by their constituent parts. Furthermore, the long-range correlations induced by the construction of these systems are expected to be reflected to some degree in their various spectra, designing a novel description of disorder. A common factor shared by all these excitations is a complex fractal energy spectrum. Could this discontinuous fractal based specific heat spectrum of SPPs be exposing the higher dimensions of reality as predicted by the Mexicans?
