Ijjas, Anna. Numerical Relativity as a New Tool for Fundamental Cosmology. arXiv:2201.03752. The astrophysicist author is presently at the NYU Center for Cosmology and Particle Physics, after stints at Princeton University, MPI Gravitational Physics and elsewhere. Here she as one woman proposes a complementary mathematical approach by which to expand and advance this celestial Earthwise project to quantify and describe the depth and breadth of our galactic universe. See also The End of Expansion by AI, Cosmin Andrei and Paul Steinhardt at 2201.07704.
Advances in our understanding of the origin, evolution and structure of the universe have long been driven by cosmological perturbation theory, model building and effective field theory. In this review, we introduce numerical relativity as a powerful new complementary method. To illustrate its power, we discuss applications to the robustness of slow contraction and inflation in homogenizing, isotropizing and flattening the universe from generic original conditions. These studies have revealed a novel, non-linear smoothing based on ultralocality that challenges the conventional view on what is required to explain the large-scale homogeneity and isotropy of the observable universe.

Javarone, Marco and Giuliano Armano. Quantum-Classical Transitions in Complex Networks. Journal of Statistical Mechanics. Online April, 2013. As these earlier fields of physics presently merge with nonlinear systems science, since both study the same phenomena, life’s dynamic intricacies can become joined with and understood via classical and quantum theories. Here University of Cagliari, Italy physicists contend that since nature and society from “biological cells to the World Wide Web” is composed of many, non-equilibrium, interacting elements, they can be modeled by way of Bose nets and Fermi-Dirac statistics. So it really is a small world and a truly unified lively universe.
This paper shows that the emergence of different structures in complex networks, such as the scale-free and the winner-takes-all networks, can be represented in terms of a quantum–classical transition for quantum gases. In particular, we propose a model of fermionic networks that allows us to investigate the network evolution and its dependence on the system temperature. Simulations, performed in accordance with the cited model, clearly highlight the separation between classical random and winner-takes-all networks, in full correspondence with the separation between classical and quantum regions for quantum gases.

Kallosh, Renata and Andrei Linde. Hybrid Cosmological Attractors. arXiv:2204.02425.. We record this latest post from the esteemed Stanford University wife and husband physicists who have continued for four decades to study how the universe seems to have begun in an explosive instant. In regard, in September 1983 I attended at Harvard the first public lecture (overhead slides) that Andrei Linde gave since coming to the USA from Russia.
We construct α-attractor versions of hybrid inflation models. In these models, the potential of the inflation field φ is uplifted by the potential of the second field χ. This uplifting ends due to a tachyonic instability with respect to the field χ, which appears when φ becomes smaller than some critical value φc. In the large N limit, these models have the standard universal α-attractor predictions. This provides significant flexibility, which can be very welcome in view of the rapidly growing amount and precision of the cosmological data. Our main result is not specific to the hybrid inflation models. (Excerpt)
Karlsson, Torgny, et al. Pre-Galactic Metal Enrichment: The Chemical Signatures of the First Stars. Reviews of Modern Physics. Online April, 2013. Also available at arXiv:1101.4024, spatial and temporal cosmic reaches are newly accessible whereof astronomers Karlsson and Joss Bland-Hawthorn, University of Sydney, with Volker Bromm, University of Texas at Austin, can detect chemical signatures from Galactic halos, Low mass galaxies, impacting Star clusters, primordial nucleosynthesis, and so on. Whom then altogether might we prodigies be, a sapient personsphere, as the phenomenal way our universe tries to describe and discover itself?
The emergence of the first sources of light at redshifts of z ~ 10-30 signaled the transition from the simple initial state of the Universe to one of increasing complexity. We review recent progress in our understanding of the formation of the first stars and galaxies, starting with cosmological initial conditions, primordial gas cooling, and subsequent collapse and fragmentation. We emphasize the important open question of how the pristine gas was enriched with heavy chemical elements in the wake of the first supernovae. We conclude by discussing how the chemical abundance patterns conceivably allow us to probe the properties of the first stars and subsequent stellar generations, and allow us to test models of early metal enrichment.

Kauffman, Stuart. Towards a Post Reductionist Science: The Open Universe. http://arxiv.org/abs/0907.2492. Posted on July 8, 2009, in part as a response to Stephen’s Hawking disavowal of a final theory, see above. Do access the full paper for as usual it is not fair to annotate Kauffman, to wit he reinterprets the multiverse in terms of Darwinian selection whereof our present cosmos is seen to possess unique “enabling laws or constraints” that imbue an unplanned potential for emergent creativeness.
The heart of what I want to explore begins with this: The very laws of physics may be open to being viewed as enabling constraints - enabling constraint laws selected by an abiotic natural selection among a set of possible laws to yield our extremely complex universe. And our single universe, not the multiverse and its attending weak Anthropic principle, may be the ’winning’ universe that is enabled by the opportunities afforded by those laws. In winning, our universe would then have evolved its laws such that the winning universe is ours. (2)

At first sight, low-temperature condensed-matter physics and early Universe cosmology seem worlds apart. Yet, in the last few years a remarkable synergy has developed between the two. It has emerged that, in terms of their mathematical description, there are surprisingly close parallels between them. This interplay has been the subject of a very successful European Science Foundation (ESF) programme entitled COSLAB (‘Cosmology in the Laboratory’) that ran from 2001 to 2006. (2793)
Kiukas, Jukka, et al. Complementary Observables in Quantum Mechanics. Foundations of Physics. Online April, 2019. Aberystwyth University, UK and University of Turku, Finland mathematicians contribute to a special issue about the esteemed University of York physicist Paul Busch (1955-2018) with whom they collaborated with for years. They advance Busch’s insights and expressions that natural phenomena tends to ever seek and reside in a dynamic duality, rather than a single state. Albeit by way unfamiliar terms and mathematical depth, a salient conclusion can be broached. This fantastic spacescape whence we find ourselves, which is yet amenable to our inquiry, is indeed distinguished by reciprocal archetypes at each and every instance. The authors open with a quote (see below) from his 1997 paper which suggests an “unsharp” milieu that is in some critical poise between complements, rather than a one thing theory. His Quantum Research Page is still online (paulbusch.wixsite.com/research-page) where an array of papers and conferences can be accessed. A special journal issue about Paul Busch is forthcoming, to which this belongs. See also Quantum Reality, Perspectivalism and Covariance by Dennis Dieks at arXiv:1905.05097 for another entry.
We review the notion of complementarity of observables in quantum mechanics, as formulated and studied by Paul Busch and his colleagues over the years. In addition, we provide further clarification on the operational meaning of the concept, and present several characterisations of complementarity—some of which new—in a unified manner, as a consequence of a basic factorisation lemma for quantum effects. We work out several applications, including the canonical cases of position–momentum, position–energy, number–phase, as well as periodic observables relevant to spatial interferometry. We close the paper with some considerations of complementarity in a noisy setting, focusing especially on the case of convolutions of position and momentum, which was a recurring topic in Paul’s work on operational formulation of quantum measurements and central to his philosophy of unsharp reality.

Kuhlmann, Meinard. What is Real? Scientific American. August, 2013. Its online title is “Physicists Debate Whether the World is Made of Particles or Fields or Something Else Entirely.” In this post Large Collider time, whose finding of the Higgs Boson is now not seen to really mean much, a major rethinking of course has commenced. Akin to Lee Smolin’s Time Reborn, e.g., a University of Bremen philosopher of physics proposes that something else and more is going on via the real interconnections between objects. As tangibly present in themselves, this dynamic domain might be seen, for example in a “Structures to the Rescue” section, as a version of the “organization” that distinguishes living organisms.
With the two standard, classical options (particles or fields) gridlocked, some philosophers of physics have been formulating more radical alternatives. They suggest that the most basic constituents of the material world are intangible entities such as relations or properties. One particularly radical idea is that everything can be reduced to intangibles alone, without any reference to individual things. It is a counterintuitive and revolutionary idea, but some argue that physics if forcing it on us. (42)
Laudisa, Federico and Carlo Rovelli. Relational Quantum Mechanics. Stanford Encyclopedia of Philosophy. 2008. Online at http://plato.stanford.edu/entries/qm-relational, a succinct entry that reality is composed of and distinguished by much more than a profusion of objects. The equally present interconnections in between every thing are nature’s salient quality and essence, a view at the edge of the 21st century turn from particles to people, a yin and yang of communion and agency.
The physical world is thus seen as a net of interacting components, where there is no meaning to the state of an isolated system. A physical system (or, more precisely, its contingent state) is reduced to the net of relations it entertains with the surrounding systems, and the physical structure of the world is identified as this net of relationships.
Lederman, Leon. The God Particle. Nature. 448/310, 2007. A perspective paper in a special section on the Large Hadron Collider, wherein nine articles provide a good review of the past 50 years of the particle paradigm. But one wonders if this endeavor has more than run its course, scoffing up funds, as others have noted, which cannot detect in its benthic depths a self-organizing cosmic to human genesis.

Papers from a 2006 Paris colloquium on the 25th anniversary of the theory that the universe, in its first instant, experienced a vast ballooning expansion from a singular point of origin. With some modifications, this phenomenon has been verified and serves to unify a number of disparate findings. A lead, notable article is by Andrei Linde on this past history, and its latest multiverse and anthropic implications.
