Highly non-Gaussian tails and primordial black holes from single-field inflation

Kavli Affiliate: Misao Sasaki | First 5 Authors: Yi-Fu Cai, Xiao-Han Ma, Misao Sasaki, Dong-Gang Wang, Zihan Zhou | Summary: For primordial perturbations, deviations from Gaussian statistics on the tail of the probability distribution can be associated with non-perturbative effects of inflation. In this paper, we present some particular examples in which the tail of […]

Coupled charge and energy transfer dynamics in light harvesting complexes from a hybrid hierarchical equations of motion approach

Kavli Affiliate: David T. Limmer | First 5 Authors: Thomas P. Fay, David T. Limmer, , , | Summary: We describe a method for simulating exciton dynamics in protein-pigment complexes, including effects from charge transfer as well as fluorescence. The method combines the hierarchical equations of motion, which are used to describe quantum dynamics of […]

Relative baryon-dark matter velocities in cosmological zoom simulations

Kavli Affiliate: George Efstathiou | First 5 Authors: Luke Conaboy, Ilian T. Iliev, Anastasia Fialkov, Keri L. Dixon, David Sullivan | Summary: Supersonic relative motion between baryons and dark matter due to the decoupling of baryons from the primordial plasma after recombination affects the growth of the first small-scale structures. Large box sizes (greater than […]

Cortical surface electrical potentials are composed of multiple bandlimited frequency components, including high-gamma

Kavli Affiliate: Kristofer Bouchard, Edward Chang | Authors: Jesse A Livezey, Ahyeon Hwang, Kseniya Usovich, Maximilian Dougherty, Edward F Chang and Kristofer E Bouchard | Summary: A common challenge in neuroscience is how to decompose noisy, multi-source signals measured in experiments into biophysically interpretable components. Analysis of cortical surface electrical potentials (CSEPs) measured using electrocorticography […]

Suboptimal phenotypic reliability impedes reproducible human neuroscience

Kavli Affiliate: Joshua Vogelstein | Authors: Aki Nikolaidis, Andrew An Chen, Xiaoning He, Russell Shinohara, Joshua Vogelstein, Michael Milham and Haochang Shou | Summary: Biomarkers of behavior and psychiatric illness for cognitive and clinical neuroscience remain out of reach. Suboptimal reliability of biological measurements, such as functional magnetic resonance imaging (fMRI), is increasingly cited as […]

Marginal Bayesian Statistics Using Masked Autoregressive Flows and Kernel Density Estimators with Examples in Cosmology

Kavli Affiliate: George Efstathiou | First 5 Authors: Harry Bevins, Will Handley, Pablo Lemos, Peter Sims, Eloy de Lera Acedo | Summary: Cosmological experiments often employ Bayesian workflows to derive constraints on cosmological and astrophysical parameters from their data. It has been shown that these constraints can be combined across different probes such as Planck […]
