The Science Potential of Characterizing Gas Giant Exoplanets with HWO

Posted by klaurent Stanford

Kavli Affiliate: Bruce Macintosh | Summary:With the ability to directly image Earth-like exoplanets and search their atmospheres for biosignatures, the upcoming Habitable Worlds Observatory (HWO) will also collect high signal-to-noise ratio (S/N) reflected-light photometry and spectra of nearby gas giant exoplanets. Such high-quality data would allow novel investigations into gas giant atmospheric composition, formation, and […]

Phase Transitions at More Unusual Values of Theta

Posted by klaurent Tokyo

Kavli Affiliate: Hitoshi Murayama | Summary:We calculate the $θ$ dependence of the vacuum energy in an infinite family of cousins of QCD, where the vacuum structure can be analyzed exactly. These theories are $mathcalN=1$ EFTs that descend from $mathcalN=2$ $SU(N_c)$ gauge theory with $N_f$ flavors of fundamental hypermultiplets, that are then deformed by anomaly mediated […]

Interpretable spherical geometry of single-cell state transitions from dominant principal components

Posted by dbos Hopkins

Kavli Affiliate: Alexander Szalay | Authors: Long Yuan, Xuyang Li, My Le, Stephanie C Hicks, Atul Deshpande, Janis M Taube and Alexander S Szalay | Summary: Single-cell RNA-seq atlases are commonly explored with nonlinear embeddings that preserve neighborhoods but provide limited coordinate-level interpretation. We asked whether projecting the dominant principal components (PCs) of single-cell gene […]

A Novel Cortico-Striatal NREM Sleep Rhythm in Mice and Non-Human Primates

Posted by dbos UCSF

Kavli Affiliate: Karunesh Ganguly | Authors: Aviv D Mizrahi-Kliger, Samantha Coury, Cameron L Woodard and Karunesh Ganguly | Summary: With practice, rapid early gains in performance are followed by a slower phase marked by kinematic refinement, automaticity and enhanced cortical and striatal interactions. While sleep is known to support early learning, its causal role in […]

Behavioral demands organize a decision process into distinct yet coordinated neural representations in parietal cortex

Posted by dbos Columbia

Kavli Affiliate: Michael Shadlen | Authors: NaYoung So, Ariel Zylberberg and Michael N Shadlen | Summary: Perceptual decisions are widely modeled as the accumulation of evidence to a bound. In the lateral intraparietal area (LIP), this computation is thought to be implemented in a low-dimensional population representation organized around the single action used to report […]

GRB 220706A: a gamma-ray burst with a month-long engine and a luminous supernova

Posted by klaurent MIT

Kavli Affiliate: Dheeraj Pasham | Summary:While the progenitors of many long gamma-ray bursts (GRBs) are well established as the core collapse of very massive, envelope-stripped, rapidly-rotating stars, it has been suggested that bursts at the extremely long end of the duration distribution may be a separate population of `ultra-long’ GRBs. With durations of thousands of […]

Resonant Gravitational Production of Chiral Dark Photons

Posted by klaurent Chicago

Kavli Affiliate: Edward Kolb | Summary:Vector fields with a chiral, parity-odd coupling to a pseudoscalar field are known to undergo resonant amplification. In this work, we study this phenomenon in the context of cosmological gravitational particle production during early-universe inflation. We consider a massive vector (dark photon) field with a parity-odd coupling to the inflaton. […]

Bootstrap certification of string order in quantum spin chains

Posted by klaurent Cornell

Kavli Affiliate: Debanjan Chowdhury | Summary:The many-body bootstrap certifies ground-state properties by minimizing energy over correlators constrained only by positivity, without any variational wavefunction. Its cost, however, grows exponentially with the size of the operators involved, placing the long-range string correlators that diagnose topological phases out of reach. We overcome this by treating string operators […]
