For more detail see as follows: arxiv.org/pdf/1604.08297v1.pdf Abstract Nonperturbative coupling of light with condensed matter in an optical cavity is expected to reveal a host of coherent many-body phenomena and states [1–7]. In addition, strong coherent light-matter interaction in a solid-state environment is of great interest to emerging quantum-based technologies [8, 9]. However, creating a system that combines a long electronic coherence time, a large dipole moment, and a high cavity quality (Q) factor has been a challenging goal [10–13]. Here, we report collective ultrastrong light-matter coupling in an ultrahigh-mobility two-dimensional electron gas in a high-Q terahertz photonic-crystal cavity in a quantizing magnetic field, demonstrating a cooperativity of ∼360. The splitting of cyclotron resonance (CR) into the lower and upper polariton branches exhibited a √ ne-dependence on the electron density (ne), a hallmark of collective vacuum Rabi splitting. Furthermore, a small but definite blue shift was observed for the polariton frequencies due to the normally negligible A 2 term in the light-matter interaction Hamiltonian. Finally, the high-Q cavity suppressed the superradiant decay of coherent CR, which resulted in an unprecedentedly narrow intrinsic CR linewidth of 5.6 GHz at 2 K. These results open up a variety of new possibilities to combine the traditional disciplines of many-body condensed matter physics and cavity-based quantum optics. The key to LENR is strong coupling between the hydrogen atom and light. When the cavity that holds the hydrogen is the optimum size, vacuum energy provides most of the energy to delocalized electrons from protons to form metalized hydrogen. The optimum cavity size does the same job as extreme pressure to form metalized hydrogen. If hydrogen is packed into a Nano cavity of the ideal size a strong coupling state might be achieved between the protons in the hydrogen and the light. In this way a state of superconductive coherence of protons might be formed: a proton condinsate. This state of superconductivity has been detected by Holmlid and Miley in iron oxide. The high temperature proton BEC might produce a super-dense state of hydrogen as measured by Holmlid where the electrons and protons are delocalized from each other, this state of charge delocalization has been seen in water inclusions inside a crystal. physics.aps.org/articles/v9/43 Water Molecule Spreads Out When Caged <http://physics.aps.org/assets/2ffd09ee-e786-4c72-844f-9b1a7df49a75/e43_1.png> What actually compresses the protons into a condinsate is vacuum energy because the cavity squeezes the light/matter condensate greatly. As described in the referenced article by looking for a hydrogen BEC in cavities, a LENR researcher could find the ideal dimensions of the Nano cavity that produces the condensed hydrogen and engineer a material that produces this ultra-dense hydrogen crystal in abundance. Currently in LENR reactors, pure chance produces metalized hydrogen in a highly porous metal that feature a wide range of cavity sizes which include the optimum cavity size that is made widely available by random chance. What really compresses hydrogen to the LENR active ultra-dense metalized state is not high pressure, but the ideal combination of cavity shape/size, light frequency, EMF environment and vacuum energy.
