The effects of star-gas interactions on binary evolution in open clusters

Posted by klaurent January 4, 2026Peking

Kavli Affiliate: Rainer Spurzem | Summary:Star-gas interactions can provide gravitational feedback that influences the dynamical evolution of stellar clusters, through processes such as dynamical friction (DF) and its non-dissipative counterpart, negative dynamical friction (NDF). Using the textttPeTar code, we perform direct $N$-body simulations of an open cluster initially containing $10^4$ stars, evolving within a gaseous […]

Shifted quantum groups via critical stable envelopes

Posted by klaurent January 4, 2026Tokyo

Kavli Affiliate: Andrei Okounkov | Summary:Given a symmetric quiver with potential, we develop a geometric construction of shifted Yangians acting on the critical cohomologies of antidominantly framed quiver varieties with extended potentials, using the $R$-matrices constructed from critical stable envelopes. We relate such Reshetikhin type Yangians to Drinfeld type Yangians arising from critical cohomological Hall […]

Bithoven: Formal Safety for Expressive Bitcoin Smart Contracts

Posted by klaurent January 4, 2026February 17, 2026Stanford

Kavli Affiliate: Hsiao-Mei (Sherry) Cho| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:The rigorous security model of Bitcoin’s UTXO architecture often comes at the cost of developer usability, forcing a reliance on manual stack manipulation that leads to critical financial vulnerabilities like signature malleability, unspendable states and unconstrained execution paths. Industry standards such as […]

Radial-glia-to-astrocyte trans-differentiation and astrocyte transcriptional convergence are coordinated by CEH-43/DLX in C. elegans

Posted by dbos January 3, 2026January 12, 2026Rockefeller

Kavli Affiliate: Shai Shaham | Authors: Simin Liu, Kenneth Bradley, Jinghong J. Tang, Yoon A. Kim, Ana Milosevic and Shai Shaham | Summary: Mammalian radial glia can remodel to become astrocytes, which acquire common transcriptional states despite spatially and lineally distinct origins. To uncover molecular programs driving convergent radial-glia-to-astrocyte transformation, we investigated development of C. […]

Detection of MEMS Acoustics via Scanning Tunneling Microscopy

Posted by klaurent January 3, 2026Delft

Kavli Affiliate: Sander Otte | Summary:Scanning tunneling microscopy (STM) and micro-electromechanical systems (MEMS) have traditionally addressed vastly different length scales – one resolving atoms, the other engineering macroscopic motion. Here we unite these two fields to perform minimally invasive-measurements of high aspect-ratio MEMS resonators using the STM tip as both actuator and detector. Operating at […]

XRISM finds the Changing-Look AGN NGC 1365 in an extended low state: A dense, highly ionized outflow obscures the central source

Posted by klaurent January 2, 2026MIT

Kavli Affiliate: Erin Kara | Summary:We present the first XRISM/Resolve observations of the active galactic nucleus, NGC 1365, obtained in 2024 February and July. NGC 1365 is known for rapid transitions between Compton-thick and Compton-thin states, along with strong absorption from a highly ionized wind. During our observations, the source is found in a persistent […]

Symmetric approximant formalism for statistical topological matter

Posted by klaurent January 2, 2026Delft

Kavli Affiliate: Anton Akhmerov | Summary:The standard approach to characterizing topological matter, computing topological invariants, fails when the symmetry protecting the topological phase is preserved only on average in a disordered system. Because topological invariants rely on enforcing the symmetry exactly, they can overcount phases by incorrectly identifying certain non-robust features as robust. Moreover, in […]

Anti-reflection coatings for highly anisotropic materials in the mid infrared

Posted by klaurent January 2, 2026February 17, 2026Stanford

Kavli Affiliate: Hsiao-Mei (Sherry) Cho| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:We develop and optimize thin anti-reflection coatings (ARCs) for highly anisotropic materials in the mid infrared. Unlike conventional ARCs that assume nearly isotropic refractive indices, this work fully integrates the anisotropic nature of materials into the design process. We describe two designs […]
