Microbes are the most prevalent and widely distributed life form on planet Earth. They are also cognitive organisms with memory and superior problem-solving skills that use quantum phase transitions during their remarkably effective gathering and dissemination of information. This narrative review explores the biological ramifications of human holobionts physically embodying the human microbiome and connecting to the Internet of Microbes (IOM) beyond our body. Within the narrative review, we consider:the ways in which our microbial co-partners exerted control over our ancestors and continue to influence our current human generation. 2)how they mold virtually every key aspect of our life and even remain with our body in death 3) how inward-looking contemplative tools such as meditation and embodied cognition provide an ideal opportunity to connect to the vast microbial network and tap the full range of human holobiont capabilities.

“…The researchers studied the light harvesting antennae of purple bacteria to construct quantum coherence maps [105]. The evolution of research on microbes and the development of new dogmas surrounding their quantum-based capacities and operating modes should prompt us to rethink our own human superorganism capacities as well.…”

“…Quantum processes play a critical role in many natural systems such as light-harvesting and photosynthetic complexes [1][2][3][4], biological vision [5,6] and light sensing [7][8][9][10] systems as well as in artificial photocatalytic [11][12][13][14] and photovoltaic [15][16][17] materials, materials for quantum sensing applications [18][19][20], or qubits [21][22][23], to name a few. Quantum coherence facilitates efficient and directional excitation energy transfer in the light-harvesting complexes [24][25][26], coupled electron-proton transfer [27][28][29], quantum tunneling [30][31][32], is critical to biological systems [33], and nonradiative energy relaxation, which realizes mechanisms of protection from the photodamage [34][35][36][37][38].

In this work, we report the development and assessment of the nonadiabatic molecular dynamics approach with the electronic structure calculations based on the linearly scaling subsystem density functional method. The approach is implemented in an open-source embedded Quantum Espresso/Libra software specially designed for nonadiabatic dynamics simulations in extended systems. As proof of the applicability of this method to large condensed-matter systems, we examine the dynamics of nonradiative relaxation of excess excitation energy in pentacene crystals with the simulation supercells containing more than 600 atoms. We find that increased structural disorder observed in larger supercell models induces larger nonadiabatic couplings of electronic states and accelerates the relaxation dynamics of excited states. We conduct a comparative analysis of several quantum-classical trajectory surface hopping schemes, including two new methods proposed in this work (revised decoherence-induced surface hopping and instantaneous decoherence at frustrated hops). Most of the tested schemes suggest fast energy relaxation occurring with the timescales in the 0.7–2.0 ps range, but they significantly overestimate the ground state recovery rates. Only the modified simplified decay of mixing approach yields a notably slower relaxation timescales of 8–14 ps, with a significantly inhibited ground state recovery.
