Are Black Hole and Cosmological Horizon Thermodynamics Necessarily Inequivalent?
Zachary J. Hoelscher
It has recently been argued that cosmological horizon thermodynamics and black hole thermodynamics are generically inequivalent in any consistent, UV complete theory of quantum gra…
Partial Relief of the Hubble Tension and a Natural Self-Interacting Dark Matter Candidate From Staged Symmetry Breaking
Zachary J. Hoelscher, Thomas W. Kephart, Robert J. Scherrer +1
The values of the Hubble constant () inferred from the cosmic microwave background (CMB) and local measurements via the distance ladder exhibit a tension. In thi…
DESI-Like Hubble Expansion From Staged Symmetry Breaking: Constraints on Renormalizable Models
Zachary J. Hoelscher, Thomas W. Kephart, Robert J. Scherrer +1
The Dark Energy Spectroscopic Instrument (DESI) second data release shows a moderate preference for dark energy with a time-varying equation of state parameter, suggesting that the…
Probing the Nature of Dark Matter Self-Interactions Through Observations of Massive Black Hole Mergers
Zachary J. Hoelscher, Kelly Holley-Bockelmann, Akaxia Cruz +1
Though the nature of dark matter remains elusive, two models have come to prominence with testable predictions: cold dark matter (CDM) and self-interacting dark matter (SIDM). Whil…
Cosmological Impacts of Black Hole Mergers: No Relief in Sight for the Hubble Tension
Zachary J. Hoelscher, Thomas W. Kephart, Kelly Holley-Bockelmann
The values of the Hubble constant inferred from local measurements and the cosmic microwave background (CMB) exhibit an approximately 5 sigma tension. Some have suggested this tens…
Semicomplete Arithmetic Sequences, Division of Hypercubes, and the Pell Constant
Zachary Hoelscher
In this paper we produce a few continuations of our previous work on partitions into fractions. Specifically, we study strictly increasing integer sequences such that the…
Counting Restricted Partitions of Integers into Fractions: Symmetry and Modes of the Generating Function and a Connection to
Zachary Hoelscher, Eyvindur Ari Palsson
Motivated by the study of integer partitions, we consider partitions of integers into fractions of a particular form, namely with constant denominators and distinct odd or even num…
