Fractal Physis: A Geometric Theory of Quantum Gravity via Structural Decoherence
Creators: name: Westwood, Danny
Publisher: name: Zenodo

Subjects: subject: Gravity

subject: Quantum field theory
subject: Physical cosmology

description: We introduce Fractal Physis, a novel geometric theory of quantum gravity that has the potential to unify quantum mechanics and general relativity through a single, empirically derived coherence support field, extracted from the fractal properties of the Cosmic Microwave Background (CMB).

 

Using wavelet-based decomposition on Planck SMICA data, we construct a scale-dependent coherence function, revealing a structural decoherence mechanism that drives the quantum-to-classical transition without invoking extra dimensions or quantized geometry.

 

Statistical analysis across multipole bands uncovers a sharp coherence collapse near a multipole of approximately 4000, where fractal structures condense into classical mass, aligning with the theory’s prediction of decoherence as a geometric constraint.

 

This framework resolves singularities via collapse wells, predicts decoherence-driven curvature, and offers a minimalist, simulation-friendly alternative to string theory and loop quantum gravity. Fractal Physis bridges quantum and gravitational realms through cosmological structure, with implications for early universe dynamics, black hole physics, and beyond.

v3 Update: 

This version of the manuscript includes several updates that strengthen the theoretical framework of Fractal Physis and its numerical validation:

Unified Action and Unitarity: Introduced a unified action in Section 4, incorporating matter, gravitational, decoherence, and entropy contributions (Eqs. (4.1)--(4.4)). Added a path integral formulation (Eq. (4.5)) to ensure unitarity, verified numerically in Section 6, where scattering probabilities sum to 1.000.

Stress-Energy Tensor Correction: Ensured the decoherence contribution to the stress-energy tensor (Eq. (5.2)) is real, resolving a potential issue with physical interpretability. Updated Section 5 to reflect this change.

Lensing Simulation Fix: Corrected the gravitational lensing simulation near Cygnus X-1 (Section 5.1 and Appendix A.2). The decoherence-induced lensing deviation now matches the predicted 0.001 arcseconds, achieved by calibrating the decoherence rate.

These updates improve the mathematical consistency, numerical validation, and empirical support of Fractal Physis, making it a more robust alternative to existing quantum gravity theories.

description: En el transcurso de los años se ha hecho más evidente la aceleración constante del cambio climático, sin embargo, es sabido que todo en el planeta tierra ha venido evolucionado desde las primeras especies hasta su entorno; para empezar es importante recordar que el mundo ha enfrentado cambios climáticos desde antes de que apareciera el primer hombre, pero dichos cambios se daban de manera natural y en un periodo de tiempo considerable lo cual permitía que su desarrollo fuera óptimo es decir sin alteraciones significativas en su ciclo de vida. No obstante, en las últimas décadas se ha identificado que las variaciones climáticas se llevan a cabo en menor tiempo, llegando al punto de acabar con el proceso natural de la tierra en la modificación de su entorno y de igual manera afectando la estabilidad de las especies hasta acabar con su existencia; debido a lo expuesto anteriormente es necesario analizar la intervención que ha tenido el hombre en dichos sucesos, por esta razón en este texto se busca identificar el impacto ambiental que genera la industria textil específicamente, con el fin de encontrar soluciones que permitan recuperar dentro de lo posible la estabilidad ambiental mejorando la relación que tiene la humanidad con los recursos naturales.

description: We study the effect of random magnetic fields in the spin-flavor precession of solar neutrinos in a three generation context, when a non-vanishing transition magnetic moment is assumed. While this kind of precession is strongly constrained when the magnetic moment involves the first family, such constraints do not apply if we suppose a transition magnetic moment between the second and third families. In this scenario we can have a large non-electron anti-neutrino flux arriving on Earth, which can lead to some interesting phenomenological consequences, as, for instance, the suppression of day-night asymmetry. We have analyzed the high energy solar neutrino data and the KamLAND experiment to constrain the solar mixing angle, and solar mass difference, and we have found a larger shift of allowed values.

description: We present a global metric describing closed timelike curves embedded in Minkowski spacetime. Physically, the metric represents an Alcubierre warp drive on a rotating platform. The physical realizability of such a metric is uncertain due to the exotic matter required to produce it. Never-the-less we suggest that this metric will have applications in more rigorously studying the behavior of quantum fields interacting with closed timelike curves.

description: The Galactic Plane Infrared Polarization Survey (GPIPS) seeks to characterize the magnetic field in the dusty Galactic disk using near-infrared stellar polarimetry. All GPIPS observations were completed using the 1.83 m Perkins telescope and Mimir instrument. GPIPS observations surveyed 76 sq-deg of the northern Galactic plane, from Galactic longitudes 18 to 56 deg and latitudes -1 to +1 deg, in the H-band (1.6 um). Surveyed stars span 7th to 16th mag, resulting in nearly 10 million stars with measured linear polarizations. Of these stars, ones with m_H < 12.5 mag and polarization percentage uncertainties under 2% were judged to be high quality and number over one million. GPIPS data reveal plane-of-sky magnetic field orientations for numerous interstellar clouds for AV values to ~30 mag. The average sky separation of stars with m_H < 12.5 mag is about 30arcsec, or about 60 per Planck polarization resolution element. Matching to Gaia DR2 showed the brightest GPIPS stars are red giants with distances in the 0.6-7.5 kpc range. Polarization orientations are mostly parallel to the Galactic disk, with some zones showing significant orientation departures. Changes in orientations are stronger as a function of Galactic longitude than of latitude. Considered at 10 arcmin angular scales, directions that show the greatest polarization fractions and narrowest polarization position angle distributions are confined to about ten large, coherent structures that are not correlated with star forming clouds. The GPIPS polarimetric and photometric data products (Data Release 4 catalogs and images) are publicly available for over 13million stars.

description: The capacity to accurately measure the food security status of children in household surveys is an essential tool for monitoring food insecurity and hunger at the most severe levels in U.S. households and for assessing programs designed to prevent or ameliorate these conditions. USDA has developed a children's food security scale to meet this measurement need. The scale is calculated from 8 questions in the 18-item food security survey module that ask specifically about food-related experiences and conditions of children. The scale measures the severity of food insecurity among children in surveyed households and identifies - in the most severe range of the scale - households in which children have been hungry at times because of a lack of household resources for food. The reliability of the children's food security scale is assessed, and the scale is compared with the household-level food security scale. Details are provided on how to calculate the children's food security scale from the questions in the standard food security survey module. The prevalence of hunger among children in U.S. households is estimated by applying the newly developed children's food security scale to data from the nationally representative Current Population Survey Food Security Supplements for the years 1995-99. Prevalence estimates are presented for all U.S. households and for subgroups defined by household structure, race and ethnicity, income, and rural/urban residence.

description: After controlling for self-selection bias, participation in the WIC program (Special Supplemental Nutrition Program for Women, Infants, and Children) has a significant positive effect on children's intakes of iron, folate, and vitamin B-6. Iron is one of the five nutrients targeted by the program, the others being protein, calcium, vitamin A, and vitamin C. Folate and vitamin B-6, along with zinc, were recommended by a 1991 USDA study as nutrients that the program should also target. The data set used, the 1994-96 Continuing Survey of Food Intake by Individuals, reflects the dramatic increase during the 1990's in the number of children in the program.

This report reviews the research designs available to evaluators for assessing the effect of USDA's food assistance and nutrition programs. The random assignment experiment is the "gold standard" design for such an evaluation. Where random assignment is impossible, quasi-experimental designs are used to infer what would have happened to program participants if the program had not existed. Eight types of quasi-experimental design are identified as having been used in evaluations of food assistance and nutrition programs, although none can guarantee unbiased estimates of program impacts.

description: Thermoelectric energy conversion is perhaps the most promising of the potential applications of molecular electronics. Ultimately, it is desirable for this technology to operate at around room temperature, and it is therefore important to consider the role of dissipative effects in these conditions. Here, we develop a theory of thermoelectricity which accounts for the vibrational coupling within the framework of Marcus theory. We demonstrate that the inclusion of lifetime broadening is necessary in the theoretical description of this phenomenon. We further show that the Seebeck coefficient and the power factor decrease with increasing reorganisation energy, and identify the optimal operating conditions in the case of non-zero reorganisation energy. Finally, with the aid of DFT calculations, we consider a prototypical fullerene-based molecular junction. We estimate the maximum power factor that can be obtained in this system, and confirm that C$_{60}$ is an excellent candidate for thermoelectric heat-to-energy conversion. This work provides general guidance that should be followed in order to achieve high-efficiency molecular thermoelectric materials.

description: Superconductivity has been induced in insulating ultra-thin films of amorphous bismuth using the electric field effect. The screening of electron-electron interaction was found to increase with electron concentration in a manner correlated with the tendency towards superconductivity. This does not preclude an increase in the density of states being important in the development of superconductivity. The superconductor-insulator transition appears to belong to the universality class of the three dimensional XY model.

description: The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) promotes breastfeeding as the preferred method for feeding infants. The breastfeeding rates among women participating in WIC, although improving, continue to be significantly lower than the Healthy People 2010 target established by the U.S. Department of Health and Human Services-that at least 75 percent of women initiate breastfeeding and at least 50 percent continue breastfeeding for at least 6 months. WIC faces several challenges in increasing breastfeeding among program participants.

description: Pulsed plasmas in liquids exhibit complex interaction between three phases of matter (liquids, gas, plasmas) and are currently used in a wide range of applications across several fields, however significant knowledge gaps in our understanding of plasma initiation in liquids hinder additional application and control; this area of research currently lacks a comprehensive predictive model. To aid progress in this area experimentally, here we present the first-known ultrafast (50 ps) X-ray images of pulsed plasma initiation processes in water (+25 kV, 10 ns, 5 mJ), courtesy of the X-ray imaging techniques available at Argonne National Laboratory's Advanced Photon Source (APS), with supporting nanosecond optical imaging and a computational X-ray diffraction model. These results clearly resolve narrow (~10 micron) low-density plasma channels during initiation timescales typically obscured by optical emission (<100 ns), a well-known and difficult problem to plasma experiments without access to state-of-the-art X-ray sources such as the APS synchrotron. Images presented in this work speak to several of the prevailing plasma initiation hypotheses, supporting electrostriction and bubble deformation as dominant initiation phenomena. We also demonstrate the plasma setup used in this work as a cheap ($

description: Food prices within States affect average monthly costs of State food benefits packages provided by the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) more than variations in WIC caseload composition do. In addition, cost-containment practices by State WIC agencies provide different levels of cost savings in different areas, which also contributes to interstate variation in benefits package costs. This study is one of the few to examine the degree to which food prices, caseloads, and cost containment practices influence costs of State WIC food benefits packages. Because few data exist on the actual food items that WIC participants purchase, the study used a scanner dataset of supermarket transactions and other sources to estimate the average monthly cost of WIC food benefits in several areas.

Milestone

description: This document is the technical elaboration milestone for FAIMS3 development. For more details on FAIMS3 see https://osf.io/mqk45/. In December 2019 the Australian Research Data Commons (ARDC) awarded a team of researchers led by Macquarie University $600,000 over three years to build a digital platform for data collection in the field and offline. This was matched by $720,920 in co-investment from project partners. FAIMS3 is a ground-up rewrite of the FAIMS Mobile (v2.6) offline-capable, geospatial, multimedia, field-data collection application. This rewrite is designed to be multi-platform, maintainable, and to support data collection at a citizen-science scale. The code and platform should last for at least five years, assuming regular maintenance. This document proposes how we can achieve these objectives.

description: A minimum of $3.6 billion would be saved if breastfeeding were increased from current levels (64 percent in-hospital, 29 percent at 6 months) to those recommended by the U.S. Surgeon General (75 and 50 percent). This figure is likely an underestimation of the total savings because it represents cost savings from the treatment of only three childhood illnesses: otitis media, gastroenteritis, and necrotizing enterocolitis. This report reviews breastfeeding trends and previous studies that assessed the economic benefits of breastfeeding.

description: The U.S. Department of Agriculture, through the Summer Food Service Program (SFSP), funds meals for children in low-income areas when school is not in session. The first comprehensive study of the SFSP since 1986 found that, in fiscal year 2001, more than 4,000 local sponsors provided about 130 million meals at more than 35,000 feeding sites. The number of children served in July 2001 (2.1 million per day) was about 14 percent of the number who received free or reduced-price school meals each day during the previous school year. On average, SFSP meals provided the levels of key nutrients recommended for school meals. However, breakfasts were slightly lower in food energy than recommended, and lunches were higher in fat. Half the SFSP sponsors were school districts, which operated about half the sites and served about half the meals. Other sponsors included government agencies, private nonprofit organizations, and residential camps. The nationally representative study, which was sponsored by USDA's Economic Research Service, surveyed State administrators, sponsor staff, and site staff on program operations and on factors that affect participation. This report summarizes the study results.

description: Collecting unsold food discarded at farmer's markets has the potential to allow nonprofit food recovery and gleaning organizations to distribute significant quantities of wholesome, unsold fruits and vegetables to needy families. Donations of this unsold produce by the participants at these markets can generate tangible benefits: increased private food assistance and better nutrition for lower income families. The Geographical Information System (GIS) analysis presented in this study indicates that there is potential to strengthen the links between farmer's markets and nonprofit food recovery and gleaning organizations in many areas of the United States.

A novel FPGA architecture supporting wide, shallow memories
Creators: name: Oldridge, Steven
Publisher: name: University of British Columbia
Year: 2009

description: The FPGAs of today are being used to implement large, system-sized circuits. Systems often require significant memory resources, and vendors have responded to these needs by embedding block memories onto their FPGAs. A proportion of these user circuits are communications-based, which have slightly different requirements from standard systems. Most notably, these circuits often contain wide data signals that must be buffered and processed efficiently and quickly. Wide signals also often originate from recently developed high-speed I/O that allow FPGAs to communicate with higher frequency circuits. This thesis investigates an architecture designed to implement wide, shallow memories on an FPGA. Under the proposed architecture, existing configuration memory normally used to control the connectivity pattern of the FPGA is made user accessible. Typically, not all the switch blocks in an FPGA are. used to transport signals. By adding only a modest amount of circuitry, the configuration memory in these unused switch blocks can be used to implement wide, shallow buffers and other similar memory structures. The size of FPGA required to implement a benchmark circuit that makes use of the wide, shallow memories, is 20 percent smaller than a standard memory architecture. In addition, the benchmark circuit is on average 40 percent faster in the proposed architecture. To get access to this memory additional circuitry must first be added. The extra transistors required will result in an area and speed overhead, even for circuits that do not make use of the new wide, shallow memories. The overhead of this circuitry was measured to be a 36 percent increase in overall FPGA area, and a 5 percent increase in critical path delay.

description: We examine how executive teams of Private Equity portfolio companies deliver superior returns through their strategic and daily operational decisions and actions. We run a comparative multiple case study of four companies, each of which went through a successful Private Equity (PE) investment cycle, and interview key members of the executive team and board as well as cross-industry experts. Using a qualitative, inductive process methodology, we match patterns between cases to tease out similarities and variance across cases and to develop a typology of actions maximizing the enterprise value at exit of the investment. We structure those actions in four distinct dimensions, which mirror the key stages of an investment, to develop a model for Private Equity operational value creation. Finally, we use dynamic capabilities and agency theories as an interpretive lens to analyze value creation in the specific context of Private Equity portfolio companies.

description: We show that a gas of relativistic electrons is a left-handed material at low frequencies by computing the effective electric permittivity and effective magnetic permeability that appear in Maxwell's equations in terms of the responses appearing in the constitutive relations, and showing that the former are both negative below the {\it same} frequency, which coincides with the zero-momentum frequency of longitudinal plasmons. We also show, by explicit computation, that the photonic mode of the electromagnetic radiation does not dissipate energy, confirming that it propagates in the gas with the speed of light in vacuum, and that the medium is transparent to it. We then combine those results to show that the gas has a negative effective index of refraction $n_{\rm eff}=-1$. We illustrate the consequences of this fact for Snell's law, and for the reflection and transmission coefficients of the gas.

description: We consider the problem of evaluating the entanglement of non-Gaussian mixed states generated by photon subtraction from entangled squeezed states. The entanglement measures we use are the negativity and the logarithmic negativity. These measures possess the unusual property of being computable with linear algebra packages even for high-dimensional quantum systems. We numerically evaluate these measures for the non-Gaussian mixed states which are generated by photon subtraction with on/off photon detectors. The results are compared with the behavior of certain operational measures, namely the teleportation fidelity and the mutual information in the dense coding scheme. It is found that all of these results are mutually consistent, in the sense that whenever the enhancement is seen in terms of the operational measures, the negativity and the logarithmic negativity are also enhanced.

description: We investigate the magnon blockade effect in a parity-time (PT) symmetric-like three-mode cavity magnomechanical system involving the magnon-photon and magnon-phonon interactions. In the broken and unbroken PT-symmetric regions, we respectively calculate the second-order correlation function analytically and numerically and further determine the optimal value of detuning. By adjusting different system parameters, we study the different blockade mechanisms and find that the perfect magnon blockade effect can be observed under the weak parameter mechanism. Our work paves a way to achieve the magnon blockade in experiment.

description: The ability to harness light-matter interactions at the few-photon level plays a pivotal role in quantum technologies. Single photons - the most elementary states of light - can be generated on-demand in atomic and solid state emitters. Two-photon states are also key quantum assets, but achieving them in individual emitters is challenging because their generation rate is much slower than competing one-photon processes. We demonstrate that atomically thin plasmonic nanostructures can harness two-photon spontaneous emission, resulting in giant far-field two-photon production, a wealth of resonant modes enabling tailored photonic and plasmonic entangled states, and plasmon-assisted single-photon creation orders of magnitude more efficient than standard one-photon emission. We unravel the two-photon spontaneous emission channels and show that their spectral line-shapes emerge from an intricate interplay between Fano and Lorentzian resonances. Enhanced two-photon spontaneous emission in two-dimensional nanostructures paves the way to an alternative efficient source of light-matter entanglement for on-chip quantum information processing and free-space quantum communications.

description: The wide band gap methylammonium lead bromide perovskite is promising for applications in tandem solar cells and light-emitting diodes. Despite its utility, there is only a limited understanding of its reproducibility and stability. Herein, the dependence of the properties, performance, and shelf storage of thin films and devices on minute changes to the precursor solution stoichiometry is examined in detail. Although photovoltaic cells based on these solution changes exhibit similar initial performance, the shelf-storage depends strongly on the precursor solution stoichiometry. While all devices exhibit some degree of healing, the bromide-deficient films show a remarkable improvement, more than doubling in their photoconversion efficiency. Photoluminescence spectroscopy experiments performed under different atmospheres suggest that this increase is due in part to a trap healing mechanism that occurs upon exposure to the environment. Our results highlight the importance of understanding and manipulating defects in lead halide perovskites to produce long-lasting, stable devices.

description: Taking a trade perspective with a focus on agri-food markets, the current foresight study employs a computable general equilibrium simulation model to quantify the implications of different future pathways of European East-West trade relations for the Commonwealth of Independent States (CIS), thereby providing insight on how best to orientate their political and trade strategies. Comparing with a baseline, two optimistic pathways explore greater market access, both within Europe (‘Deep integration’) and globally (‘trade liberalisation’). In contrast, an isolationist ‘trade bloc’ pathway reflecting a deteriorating political situation between Russia and the West is also examined. In the ‘baseline’, Deep and Comprehensive Free Trade Agreement (DCFTA) members realise market gains, whilst intra-CIS trade diversion effects are small. The ‘deep integration’ scenario (‘liberalisation’ scenario) generates significant relative benefits for DCFTA signatories’ agrifood (non-agrifood) activities. In both of these trade reform narratives, the Eurasia Economic Union (EAEU) economic gains are biased in favour of Russia’s energy sector resulting in greater import dependence on agrifood commodities from the EU. The isolationist trade narrative nurtures EAEU agrifood activity, although at the cost of its macro-economic growth.

description: Drift-pair bursts are an unusual type of solar low-frequency radio emission, which appear in the dynamic spectra as two parallel drifting bright stripes separated in time. Recent imaging spectroscopy observations allowed for the quantitative characterization of the drifting pairs in terms of source size, position, and evolution. Here, the drift-pair parameters are qualitatively analyzed and compared with the newly-developed Monte Carlo ray-tracing technique simulating radio-wave propagation in the inhomogeneous anisotropic turbulent solar corona. The results suggest that the drift-pair bursts can be formed due to a combination of the refraction and scattering processes, with the trailing component being the result of turbulent reflection (turbulent radio echo). The formation of drift-pair bursts requires an anisotropic scattering with the level of plasma density fluctuations comparable to that in type III bursts, but with a stronger anisotropy at the inner turbulence scale. The anisotropic radio-wave scattering model can quantitatively reproduce the key properties of drift-pair bursts: the apparent source size and its increase with time at a given frequency, the parallel motion of the source centroid positions, and the delay between the burst components. The trailing component is found to be virtually co-spatial and following the main component. The simulations suggest that the drift-pair bursts are likely to be observed closer to the disk center and below 100 MHz due to the effects of free-free absorption and scattering. The exciter of drift-pairs is consistent with propagating packets of whistlers, allowing for a fascinating way to diagnose the plasma turbulence and the radio emission mechanism.

description: Despite many advances towards improving the stability of organic photovoltaic devices, environmental degradation under ambient conditions remains a challenging obstacle for future application. Particularly conventional systems employing fullerene derivatives are prone to oxidise under illumination, limiting their applicability. Herein, we report on the environmental stability of the small molecule donor DRCN5T together with the fullerene acceptor PC70BM. We find that this system exhibits exceptional device stability, mainly due to almost constant short-circuit current. By employing ultrafast femtosecond transient absorption spectroscopy we attribute this remarkable stability to two separate mechanisms: 1) DRCN5T exhibits high intrinsic resistance towards external factors, showing no signs of deterioration. 2) The highly sensitive PC70BM is stabilised against degradation by the presence of DRCN5T through ultrafast long-range energy transfer to the donor, rapidly quenching the fullerene excited states which are otherwise precursors for chemical oxidation. We propose that this photoprotective mechanism be utilised to improve the device stability of other systems, including non-fullerene acceptors and ternary blends.
