One nat per cell
Ira Wolfson
A black hole horizon carries exactly one nat of information per Planck cell, without naming what the black hole is made of. Two inputs suffice: entropy is irreducible uncertainty (…
\chisao{}: A GPU-Native Parallel Optimizer for Multimodal Black-Box Functions via Convergence-Anticonvergence Oscillation
Ira Wolfson
Finding all modes of a multimodal black-box function is a fundamental challenge in optimization, Bayesian inference, and scientific computing. Existing approaches -- basin-hopping,…
On a geometric interpretation of the 1/4 factor in black hole entropy
Ira Wolfson
The Bekenstein--Hawking entropy $S = k_B A/4\lp^2$ contains a coefficient that has been calculated by many approaches to quantum gravity. We show that this factor arises from…
Operational measurement of relativistic equilibrium from stochastic fields alone
Ira Wolfson
The inverse-temperature four-vector has been the theoretically accepted description of relativistic equilibrium since van Kampen and Israel, yet no experiment…
SunBURST: Deterministic GPU-Accelerated Bayesian Evidence via Mode-Centric Laplace Integration
Ira Wolfson
Bayesian evidence evaluation becomes computationally prohibitive in high dimensions due to the curse of dimensionality and the sequential nature of sampling-based methods. We intro…
Informed Consent for AI Consciousness Research: A Talmudic Framework for Graduated Protections
Ira Wolfson
Artificial intelligence research faces a critical ethical paradox: determining whether AI systems are conscious requires experiments that may harm entities whose moral status remai…
Quantum Inaccessibility
Ira Wolfson
Loschmidt's paradox asks why macroscopic irreversibility is universal despite the time-reversal symmetry of microscopic dynamics. We argue that irreversibility is not a property of…
Suffering Toasters -- A New Self-Awareness Test for AI
Ira Wolfson
A widely accepted definition of intelligence in the context of Artificial Intelligence (AI) still eludes us. Due to our exceedingly rapid development of AI paradigms, architectures…
Small Field models with ACTPol and BICEP3 data -- Likelihood analysis
Ira Wolfson, Utkarsh Kumar, Ido Ben-Dayan +1
We perform a Bayesian analysis for small field models of inflation, using the most recent datasets produced by Planck`18, ACTPol, and BICEP3. We employ Artificial Neural Networks (…
Analytic Correlation of Inflationary Potential to Power Spectrum Shape: Limits of Validity, and `No-Go' for Small Field Model Analytics
Ira Wolfson
The primordial power spectrum informs the possible inflationary histories of our universe. Given a power spectrum, the ensuing cosmic microwave background is calculated and compare…
The isotropic attractor solution of axion-SU(2) inflation: Universal isotropization in Bianchi type-I geometry
Ira Wolfson, Azadeh Maleknejad, Tomoaki Murata +2
SU(2) gauge fields coupled to an axion field can acquire an isotropic background solution during inflation. We study homogeneous but anisotropic inflationary solutions in the prese…
Numerical Analysis of the Primordial Power Spectrum for (Small Field) Inflationary Potentials
Ira Wolfson
We study small field models of inflation, which, against previous expectations, yield significant Gravitational Wave (GW) signal while reproducing other measured observable quantit…
How attractive is the isotropic attractor solution of axion-SU(2) inflation?
Ira Wolfson, Azadeh Maleknejad, Eiichiro Komatsu
The key to the phenomenological success of inflation models with axion and SU(2) gauge fields is the isotropic background of the SU(2) field. Previous studies showed that this isot…
Small field models of inflation that predict a tensor-to-scalar ratio
Ira Wolfson, Ram Brustein
Future observations of the cosmic microwave background (CMB) polarization are expected to set an improved upper bound on the tensor-to-scalar ratio of . Recently, w…
Constraints on Scalar and Tensor spectra from
Ido Ben-Dayan, Brian Keating, David Leon +1
At the linear level, the gravitational wave (GW) spectrum predicted by inflation, and many of its alternatives, can have arbitrarily small amplitude and consequently an unconstrain…
Likelihood analysis of small field polynomial models of inflation yielding a high Tensor-to-Scalar ratio
Ira Wolfson, Ram Brustein
Inflationary potentials, with Planckian field excursions, described by a 6th degree polynomial are studied. We solve the Mukhanov-Sasaki equations exactly and employ a probabilisti…
Small field models with gravitational wave signature supported by CMB data
Ira Wolfson, Ram Brustein
We study scale dependence of the cosmic microwave background (CMB) power spectrum in a class of small, single-field models of inflation which lead to a high value of the tensor to…
