Hallgren Entropic Quantum Mechanics
No full textThis project presents Hallgren Entropic Quantum Mechanics (HEQM), a reformulation of quantum theory where entropy growth limits which quantum states remain physically possible. The framework replaces observer-based collapse with a causal entropy field that prunes unreachable branches from the wavefunction. HEQM offers a unified explanation for collapse, irreversibility, and the arrow of time, and makes predictions that distinguish it from standard quantum mechanics
Hallgren General Relativity: A Max-Density, Causal Stillness Model
No full textClassical General Relativity (GR) admits singularities with divergent curvature and density. I propose Hallgren General Relativity (HGR): gravitational collapse halts at a universal
maximum density ρmax enforced by causality and entropy, replacing the singularity by a finite causal stillness core of radius rcor

Hallgren Entropy and Cosmology: A First-Principles Derivation of the CMB Acoustic Peak Angle
No full textThis working paper presents a new derivation of the angular scale of the first peak in the cosmic microwave background using Hallgren General Relativity and Hallgren entropy. The model relies only on the growth of causal entropy time, without using inflation, dark energy, or Friedmann equations. By treating the sound horizon as a causal feature governed by entropy-based expansion, the predicted angular scale closely matches Planck satellite observations. All assumptions are physically standard, and no tuning or fitting is required. The result supports HGR as a predictive, entropy-driven framework for early-universe cosmology
Estimating the Causal Saturation Scale from Gravitational Wave Echoes: An Empirical Probe of Hallgren General Relativity
No full textThis project explores gravitational wave echoes as signatures of causal entropy saturation in Hallgren General Relativity (HGR). By deriving a predictive echo delay curve from a finite entropy core and calibrating it to GW150914, the model offers a falsifiable framework with a single physical parameter, testable across future black hole mergers

A note on a Claim of Eldar & Hallgren: LLL already solves it
No full textIn a recent talk of Hallgren on a joint work with Eldar (Sept 21, 2021, Simons Institute), a polynomial-time quantum algorithm for solving BDD in a certain class of lattices was claimed. We show here that known classical (and even, deterministic) polynomial-time algorithms already achieve this result
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
