Kavli Affiliate: Masahito Yamazaki | Summary:Conventional quantum integrability is encoded in a commuting algebra of transfer matrices. By contrast, several models possess additional non-commuting conserved charges with important physical consequences, yet the nature of the corresponding symmetry has remained elusive. Focusing on the XXZ spin chain at roots of unity, we show that the non-Abelian […]
Kavli Affiliate: Masahito Yamazaki | Summary:We establish a direct connection between Onsager symmetry, duality defects, and quantum integrability in the XXZ spin chain at roots of unity, $Δ=(q+q^-1)/2$ with $q^N=pm1$. Using a non-Abelian algebra of transfer matrices governed by an unbalanced version of the Yang–Baxter/RLL relation, we construct an explicit lattice realization of the Onsager […]
Kavli Affiliate: Erin Kara | Summary:The X-ray source in AGN is commonly referred to as the corona by analogy to stellar coronae. The similarities between the two suggest that the heating mechanism of AGN coronae is magnetic reconnection — as in cool stars — but this has not yet been directly observed. This work presents […]

Kavli Affiliate: David W. Miller | Summary:Neural swipe decoders are typically tied to the keyboard they were trained on, requiring a new corpus and training run for each layout. In this report, we document our approach toward training models that can function on any contiguous mobile keyboard layout. At each point along the swipe, our […]
Kavli Affiliate: Susan Clark | Summary:Atomic hydrogen (HI) is the dominant baryonic component of the interstellar medium (ISM) in Milky Way-like galaxies and the reservoir from which molecular clouds and stars ultimately form. The condensation of diffuse HI into cold structures is governed by a complex interplay between radiative cooling, turbulence, magnetic fields, stellar feedback, […]
Kavli Affiliate: David Muller | Summary:Behavioral Foundation Models (BFMs) offer a promising path toward universal physics-based character control by organizing a rich repertoire of physically plausible behaviors into a latent space, guided by a large-scale motion dataset. While these models excel at time-invariant tasks, such as goal-reaching and state-based reward optimization, their latent space does […]
Kavli Affiliate: Edward Kolb | Summary:We study cosmological gravitational particle production (CGPP) of dark matter in two-field inflationary backgrounds with both flat and curved field-space geometries. As a concrete realization of broader multifield mechanisms, we adopt a Starobinsky+quadratic potential and construct benchmark scenarios that interpolate between the flat field-space limit and the sidetracked attractor on […]
Kavli Affiliate: Susan Clark | Summary:Zeeman splitting in spectral lines — both in emission and absorption — provides direct estimates of magnetic field strength and direction in magnetized gas in our own Milky Way and in external galaxies. We discuss the potential for using the Square Kilometre Array (SKA) to measure the Zeeman effect in […]
Kavli Affiliate: Laura Schaefer | Summary:Earth and Venus represent two evolutionary outcomes arising from initially molten ‘magma ocean’ periods, followed by lifetimes of chemical and geophysical divergence. Their physics is common to all rocky planets and is accessible to simulations that adopt coupled interior-atmosphere modelling approaches. Our understanding of planet histories and interpretation of current […]
