Strain-controlled magnetism and magnetoelasticity in monolayer NiPS$_3$ and CrPS$_4$

Posted by klaurent Delft

Kavli Affiliate: Herre Van Der Zant | Summary:We develop a first-principles framework for magnetoelastic coupling in two-dimensional magnets based on a strain-dependent Heisenberg model. In this approach, strain derivatives of the exchange interactions provide direct access to magnetostriction and to the magnetic renormalization of the elastic tensor, establishing a microscopic link between spin interactions and […]

A Pair of Warm Saturn-mass Planets near the 2:1 Mean Motion Resonance around TOI-3850

Posted by klaurent MIT

Kavli Affiliate: Avi Shporer | Summary:Warm Jupiters, with orbital periods of $10$–$200~rmdays$ and radii exceeding $8~R_oplus$, are a relatively understudied class of exoplanets occupying the parameter space between hot Jupiters and more widely separated, colder Jupiter analogs. In this work, we report the detection of a multi-planet warm Jupiter system around TOI-3850 (TIC-143008050), a moderately […]

Cell-type-specific cortical feedback coordinates hierarchical credit assignment

Posted by dbos Columbia

Kavli Affiliate: Rui Costa | Authors: Will Greedy, Heng Wei Zhu, Alexia Duriez, Joseph Pemberton, Patrick T. McCarthy, Kevin Kermani Nejad and Rui Ponte Costa | Summary: Learning is thought to arise from synaptic modifications embedded in brain-wide circuits 1–3, yet how such circuits coordinate plasticity to support complex behaviour is not known 4,5. Inspired […]

Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory

Posted by klaurent Caltech

Kavli Affiliate: Dimitri Mawet| Summary:The Habitable Worlds Observatory (HWO) is a future NASA flagship mission concept identified by the Astro2020 Decadal Survey as the highest priority for large space missions. HWO should conduct "transformative astrophysics" and search for biosignatures in the atmospheres of approximately 25 potentially Earth-like planets. To further the early-stage development of HWO, […]

CausalSplat: Towards Comprehensive Hierarchical Reasoning in 3D Gaussian Splatting

Posted by klaurent Caltech

Kavli Affiliate: Wei Gao| Summary:While 3D Gaussian Splatting (3DGS) has advanced open vocabulary scene understanding, existing methods remain confined to explicit queries. They struggle to interpret implicit intents, complex spatial constraints, and commonsense reasoning required for practical embodied interactions. To address this gap, we introduce the task of reasoning 3D Gaussian segmentation and construct two […]

Assessing fidelity-limiting factors and achieving single-qubit gate fidelity beyond 99.999% in driven silicon spin qubits

Posted by klaurent Delft

Kavli Affiliate: Giordano Scappucci | Summary:In semiconductor single-spin qubits, high-fidelity quantum gates have been demonstrated; however, achieving consistent performance remains challenging due to variations in driven qubit coherence, which is less explored than free-evolution coherence such as $T_2^*$. Here, we report single-qubit gate fidelities above 99.999%, achieved by dramatically extending the driven-spin coherence time and […]

Visual Geometry Foundation-Aware Gaussians for Single-Frame Surround-View Driving Reconstruction

Posted by klaurent Caltech

Kavli Affiliate: Wei Gao| Summary:Single-frame surround-view reconstruction faces severe geometric instability and rendering artifacts due to minimal inter-camera overlap. While existing methods rely on complex decoders or auxiliary cues, they remain bottlenecked by the weak geometric capacity of upstream features. We argue that leveraging pretrained visual geometry priors strengthens upstream representations and alleviates the geometric […]

Evidence for Enhancement in the Rate of Fast Radio Bursts Toward Galaxy Clusters

Posted by klaurent MIT

Kavli Affiliate: Kiyoshi Masui | Summary:Massive galaxy clusters can introduce gravitational lensing and populations of suppressed star formation member galaxies into the line of sight, potentially changing the distribution of observable sources toward them from that of the average sky. As a result, Fast Radio Bursts (FRBs) aligned with galaxy clusters can provide a unique […]
