Recent attempts to establish the quantum boundaries of life is pursued. A pre-existing view of quantum biology is supplemented by the formulation of modern advances in theoretical chemical physics ...and quantum chemistry. The extension to open system dynamics entails a self-referential amplification supporting the signature of life as well as consciousness via long-range correlative information, ODLCI. The associated negentropic coherence permeates hierarchical and functional organization at multiple levels. In this communication we will derive and review one of the most important mathematical tools, i.e., the combined use of the Fourier- and the Laplace transform. It is shown that an underlying operator algebra facilitates the formulation of the conjugate relationship between energy-time and momentum-space. Implications from augmented general dilation analytic operator families provide novel information-based representations and yield,
inter alia
, a thermo-qubit syntax for communication, which are required to support the quantum Darwinian view of life.

The present rate of growth of powerful AI systems motivates an accurate comparison between the notion of computers and the workings of natural sciences. Statements such as “intelligence doesn't ...require flesh, blood or carbon atoms” or “it's computation all the way down” incite a substrate‐independent view, providing shortcuts for Darwinian evolution and the possible appearance of sentient machines. This view is discussed and contrasted from a quantum chemical perspective. The qualitative difference between the developed AI and the evolved HI is recognized and the importance of a material constituent, formulated in terms of energy‐temperature, conjugate to an immaterial ingredient, in the context of time‐entropy, is pointed out as a necessary feature. The popular dictum “it from bit” does not appear valid unless amended with its obverse “bit from it.”
Artificial intelligence, AI, and human intelligence, HI, is analysed from a quantum chemical perspective. Carbon prejudice versus ‘computation all the way down’ is compared with reference to substrate dependent disciplines, such as chemistry and biology. The self‐referential law of nature, starting at the microscopic level, will address the complexity of living systems, from atomic‐molecular levels to biological processes all the way up to our present acumen.

It is generally agreed amongst philosophers and neuroscientists that the main obstacle between the science of the brain and the conscious nature of the mind is rooted in an objective-subjective ...dichotomy. It is further common to classify natural sciences in terms of their epistemological values and their ontological existential attributes. As a result, one concludes that a computer that is useful for studying nature, such as the conscious mind, is not itself part of nature, or as phrased differently by the noted philosopher, John Searle, ‘there are no Turing Machines in nature! However, the great physicist John Archibald Wheeler, by declaring the famous dictum, ‘it from bit’, did impart a somewhat different approach to the true nature of reality. To reconcile the two contrasting portraits, a different picture, based on the principle of self-reference, will be presented, and applied to the brain-mind problem. It is demonstrated how this principle imparts a thermo-qubit syntax, i.e., ‘bit from it’, for communication between increasingly more complex physical systems. Altogether, the steady state situation produces negentropic pockets for quantification and storage of information. The communication protocol entails cognition mechanisms that display unexpected equivalences that prompts fundamental interpretations of general optical illusions such as Necker’s cube, the Rubin vase, and the Spinning Dancer. The derived syntax also embodies an interesting deconstruction of the recently observed dodecanogram brain signal, experimentally elucidated by Anirban Bandyopadhyay and his team.
During 2016, we celebrate the 100th anniversary of the birth of Per-Olov Löwdin. He was appointed to the first Lehrstuhl in quantum chemistry at Uppsala University in 1960. Löwdin introduced quantum ...chemistry as a field in its own right by formulating its goals, establishing fundamental concepts, like the correlation energy, the method of configuration interaction, reduced density matrices, natural spin orbitals, charge and bond order matrices, symmetric orthogonalisation, and generalised self-consistent fields. His exposition of partitioning technique and perturbation theory, wave and reaction operators and associated non-linear summation techniques, introduced mathematical rigour and deductive order in the interpretative organisation of the new field. He brought the first computer to Uppsala University and pioneered the initiation of 'electronic brains' and anticipated their significance for quantum chemistry. Perhaps his single most influential contribution to the field was his education of two generations of future faculty in quantum chemistry through Summer Schools in the Scandinavian Mountains, Winter Institutes at Sanibel Island in the Gulf of Mexico. Per-Olov Löwdin founded the book series Advances in Quantum Chemistry and the International Journal of Quantum Chemistry. The evolution of quantum chemistry is appraised, starting from a collection of cross-disciplinary applications of quantum mechanics to the technologically advanced and predominant field of today, virtually used in all branches of chemistry. The scientific work of Per-Olov Löwdin has been crucial for the development of this new important province of science.
This article honours Michael Baer on the occasion of his 80th birthday and celebrates his scientific contributions to non-adiabatic chemical physics. This undertaking prompts the presentation of a ...first principles molecular theory of the genetic code. Jacques Monod's classic essay, 'Chance and Necessity', is exercised as a platform for this discussion. In particular the controversial concept of teleonomy is considered and evaluated in relation to modern developments in chemical physics.
In this communication we take up the significance and purpose of selecting the proper coordinate system from the flat space‐time of non‐relativistic theories to the quantum theoretic formulation of ...general relativity. The universal background problem is straight forwardly framed as a momentum‐energy portrait in nexus with its space‐time conjugates. The description is based on operator matrix algebra, where the related analogue of the secular equation yields a Klein‐Gordon type equation and the associated Minkowski eigentime element. The energy‐momentum and their conjugate partners are represented by spaces that have (+,−) signatures. The general theory implicates both non‐zero‐ and zero rest‐mass entities, and it is proved that the conjugate relationship between energy and time provide a simple derivation of the Schwarzschild line element for the case of a gravitational field outside a spherical non‐rotational uncharged mass. This result, indicating the appearance of a black hole as a true singularity in the energy‐time formulation, and obtained as a direct consequence of their conjugate relationship, manifests background independence in concert with Einstein’s equivalence principle. Inducing a reformulation of the Lorentz Transformation respecting the indefinite Minkowski metric, displays an interesting relation between complex dilations and indefinite metric spaces, validating the complex symmetric ansatz.
It is proven that a basic quantum theoretic ansatz of momentum‐energy and their conjugates, space time, impart the celebrated Schwarzschild metric, showing contrary to the classical case, the Schwarzschild radius to be a true theoretical singularity. An linear mapping of the Lorentz transformation in the Minkowski space displays an interesting relation between complex dilation and indefinite metric spaces.
