Star cluster formation from turbulent clumps. V. Stellar clustering around massive stars

Aayush Gautam, Juan P. Farias, Jonathan C. Tan · 2026

Massive stars (> 8 $M_\odot$) are known to have high degrees of multiplicity, e.g., with about 60% in triples or higher-order multiples. Such high levels of multiplicity may arise during formation (pr…

Confinement-Connectivity Coupling Enables High-Efficiency Piezoionic Transduction

Tofayel Ahammad Ovee, Daniel Kroeger, Jean-Francois Louf · 2026

Piezoionic hydrogels offer a route to mechanically driven bioelectronic interfaces, but their output is limited by rapid, symmetric ion redistribution that dissipates charge gradients. In biological e…

Quantum Coordination without Conditioning under Restricted Information

Faisal Shah Khan · 2026

We study coordination under restricted information, where classical local models fail to implement certain correlated distributions because agents cannot condition on past history. We show that quantu…

Derivation of the Born Rule and Operational Quantum Formalism in the Accessibility Framework through Boundary Reduction

Everett Fall, Hironori Kondo · 2026

We show that the operational quantum formalism -- the Born rule, L\"uders state updating, quantum interference, non-Markovian effective dynamics, and Bell inequality violation at the Tsirelson bound \…

Perturbative Coulomb branches on $\mathbb{R}^3\times S^1$: the global D-term potential

Arash Arabi Ardehali, Daniel J. Resnick · 2026

We find the perturbative potential on the 3d $\mathcal{N}\!=\!2$ Coulomb branch arising from a chiral 4d $\mathcal{N}\!=\!1$ gauge theory on $\mathbb{R}^3 \times S^1$, zeta-regularizing the D-term cou…
