Cross-Spectral Witness for Hidden Nonequilibrium Beyond the Scalar Ceiling
Yuda Bi, Vince D Calhoun
Partial observation is a pervasive obstacle in nonequilibrium physics: coarse graining may absorb hidden forcing into an apparently equilibrium-like reduced description, so a drive…
Timescale Coalescence Makes Hidden Persistent Forcing Spectrally Dark
Yuda Bi, Chenyu Zhang, Vince D Calhoun
Under coarse observation, unresolved slow forcing can remain dynamically active yet locally invisible to reduced spectral inference. For a solvable driven AR benchmark, the lo…
A Bell Experiment in an Entangled Universe
Pablo Tejerina-Pérez, Daniele Bertacca, Raul Jimenez +1
We propose a possible quantum signature of the early Universe that could lead to observational imprints of the quantum nature of the inflationary period. Graviton production from t…
Grokking as a Falsifiable Finite-Size Transition
Yuda Bi, Chenyu Zhang, Qiheng Wang +1
Grokking -- the delayed onset of generalization after early memorization -- is often described with phase-transition language, but that claim has lacked falsifiable finite-size inp…
Conditioning on a Volatility Proxy Compresses the Apparent Timescale of Collective Market Correlation
Yuda Bi, Vince D Calhoun
We address the attribution problem for apparent slow collective dynamics: is the observed persistence intrinsic, or inherited from a persistent driver? For the leading eigenvalue f…
Reservoir Subspace Injection for Online ICA under Top-n Whitening
Wenjun Xiao, Yuda Bi, Vince D Calhoun
Reservoir expansion can improve online independent component analysis (ICA) under nonlinear mixing, yet top- whitening may discard injected features. We formalize this bottlenec…
A 1/R Law for Kurtosis Contrast in Balanced Mixtures
Yuda Bi, Wenjun Xiao, Linhao Bai +1
Kurtosis-based Independent Component Analysis (ICA) weakens in wide, balanced mixtures. We prove a sharp redundancy law: for a standardized projection with effective width $R_{\mat…
