About P-adic Numbers and Professor Igor Volovich on the Occasion of his 80th Anniversary
Paul H Frampton
We recall a 1987 paper written by Volovich and our subsequent work with Okada which established the Feyman rules for the p-adic string and the related non-local field theory which…
Swampland Conjectures and Cosmological Expansion
Claudio Corianò, Paul H. Frampton
Swampland conjectures (SCs) of string theory require that a constant cosmological constant be replaced by a time-dependent scalar-field quintessence with constrained parameters…
Predictions of Entropic Gravity
Paul H. Frampton, Gabriel Karl
We discuss consequences of an entropic view of gravity, which differs in details from the original proposals of Jacobson and Verlinde. We assume the entropy is localized in the deg…
Using Newton's Law for Dark Energy
Paul Frampton
A model is introduced in which Newton's law is modified between matter and dark energy corpuscles (DECs). The model predicts that the DEC component is presently decelerating in its…
Models for Little Rip Dark Energy
Paul H. Frampton, Kevin J. Ludwick, Shin'ichi Nojiri +2
We examine in more detail specific models which yield a little rip cosmology, i.e., a universe in which the dark energy density increases without bound but the universe never reach…
Seeking Evolution of Dark Energy
Paul H. Frampton, Kevin J. Ludwick
We study how observationally to distinguish between a cosmological constant (CC) and an evolving dark energy with equation of state . We focus on the value of redshift Z* at…
Entropic Inflation
Damien A. Easson, Paul H. Frampton, George F. Smoot
One of the major pillars of modern cosmology theory is a period of accelerating expansion in the early universe. This accelerating expansion, or inflation, must be sustained for at…
Entropic Accelerating Universe
Damien A. Easson, Paul H. Frampton, George F. Smoot
To accommodate the observed accelerated expansion of the universe, one popular idea is to invoke a driving term in the Friedmann-Lemaitre equation of dark energy which must then co…
Black Holes as Dark Matter
Paul H. Frampton
While the energy of the universe has been established to be about 0.04 baryons, 0.24 dark matter and 0.72 dark energy, the cosmological entropy is almost entirely, about $(1 - 10^{…
Identification of All Dark Matter as Black Holes
Paul H. Frampton
For the universe I use dimensionless entropy for which the most convenient unit is the googol () and identify all dark matter as black holes whereupon the p…
Desperately Seeking Intermediate-Mass Black Holes
Paul H. Frampton
Observational searches for Intermediate Mass Black Holes (IMBHs), defined to have masses between 30 and 300,000 solar masses, provide limits which allow up to ten percent of what i…
Past Eras In Cyclic Cosmological Models
Paul H. Frampton
In infinitely cyclic cosmology past eras are discussed using set theory and transfinite numbers. One consistent scenario, already in the literature, is where there is always a coun…
Particle phenomenology and Maldacena
Paul H. Frampton
A brief review is offered of employing Maldacena's AdS/CFT correspondence in attempting to identify a model which extends to higher energy the standard model of particle phenomenol…
Multifluid Models for Cyclic Cosmology
Irina Aref'eva, Paul H. Frampton, Shinya Matsuzaki
Inspired by the Landau two-fluid model of superfluidity, we consider a similar multifluid description for cosmology where two normal fluids occur for matter and radiation respectiv…
Constraints on Deflation from the Equation of State of Dark Energy
Lauris Baum, Paul H. Frampton, Shinya Matsuzaki
In cyclic cosmology based on phantom dark energy the requirement that our universe satisfy a CBE-condition ({\it Comes Back Empty}) imposes a lower bound on the number …
What is the entropy of the universe?
Paul Frampton, Stephen D. H. Hsu, Thomas W. Kephart +1
Standard calculations suggest that the entropy of our universe is dominated by black holes, whose entropy is of order their area in Planck units, although they comprise only a tiny…
Entropy of Contracting Universe in Cyclic Cosmology
Lauris Baum, Paul H. Frampton
Following up a recent proposal \cite{BF} for a cyclic model based on phantom dark energy, we examine the content of the contracting universe (cu) and its entropy . We find…
Turnaround in Cyclic Cosmology
Lauris Baum, Paul H. Frampton
It is speculated how dark energy in a brane world can help reconcile an infinitely cyclic cosmology with the second law of thermodynamics. A cyclic cosmology is described, in which…
Anomaly Cancellation and Conformality in Quiver Gauge Theories
Edoardo Di Napoli, Paul H. Frampton
Abelian quiver gauge theories provide nonsupersymmetric candidates for the conformality approach to physics beyond the standard model. Written as , gauge theor…
Suggestion of Explicit Field Transformations underlying Misaligned Supersymmetry
Paul H. Frampton
In order that nonsupersymmetric quiver gauge theories can satisfy naturalness requirements to all orders of perturbation theory, one expects a global symmetry similar to, but diffe…
Testable and Untestable Aspects of Dark Energy
Paul H. Frampton
It has been suggested that dark energy will lead to a frequency cut-off in an experiment involving a Josephson junction. Here we show that were such a cut-off detected, it would ha…
Conformality Emergent In String Phenomenology
Paul H. Frampton
Use of the AdS/CFT correspondence to arrive at phenomenological gauge field theories is discussed, focusing on the orbifolded case without supersymmetry. An abelian orbifold with t…
Chiral Fermions and Quadratic Divergences
Xavier Calmet, Paul H. Frampton, Ryan M. Rohm
In an approach towards naturalness without supersymmetry, renormalization properties of nonsupersymmetric abelian quiver gauge theories are studied. In the construction based on cy…
String Theory and Unification
Paul H. Frampton
The use of the AdS/CFT correspondence to arrive at quiver gauge field theories is discussed. An abelian orbifold with the finite group can give rise to a nonsupersymmetric…
