Secular Spin–Orbit Resonances of Black Hole Binaries in AGN Disks
The spin–orbit misalignment of stellar-mass black hole (sBH) binaries provides important constraints on the formation channels of merging sBHs. Here, we study the role of secular spin–orbit resonance in the evolution of an sBH binary component around a ...

Binary Gravitational Perturbations and Their Influence on the Habitability of Circumstellar Planets
In order to assess the habitability of planets in binary star systems, not only astrophysical considerations regarding stellar and atmospheric conditions are needed, but orbital dynamics and the architecture of the system also play an important role. Due

Perfect Absorption Metasurfaces with Multiple Meta-Resonances
We show that the hybrid resonances of a DMR backed by a cavity are meta-resonances, in that they can be made as perfect as possible by fine tuning the structural parameters but without the requirements of extreme materials properties, such as zero ...

Chiral dopants induce supramolecular chirality in an achiral polymer (PFO), generating spin‐polarized carriers via the chiral‐induced spin selectivity (CISS) and suggesting a possible contribution of Spin‐polarized carrier transport to circularly polarized electroluminescence (CPEL).

Coupling of Dynamical Tide and Orbital Motion
The dynamical tide consists of various waves that can resonate with orbital motion. We test this coupling of the dynamical tide and orbital motion using a simple 2D shallow water model, which can be applied to a rocky planet covered with a thin ocean or ...

SHAPE RESONANCES IN PHOTOIONIZATION: CORRELATION WITH STO-3G MO RESULTS
Shape resonances in nine linear molecules are investigated by multiple-scattering and molecular-orbital calculations. Each resonance correlates with a bound-state virtual orbital.

A graphene‐supported 2D metal–organic network stabilizes highly reactive Fe(I)‐N4 single sites through Co‐induced charge redistribution. Combined experiments and theory reveal Fe(I) formation, oxygen‐driven oxidation, and O2 activation mechanisms, offering a strategy to access low‐valent iron centers relevant to catalytic and biological processes ...

Orbital stability of compact three-planet systems
Context. Observational surveys show that at least ∼30% of short-period multi-planet systems contain planets in tightly packed orbits. Some of these systems are locked in stable chains of mean-motion resonances.

Timescales of Chaos in the Inner Solar System: Lyapunov Spectrum and Quasi-integrals of Motion
Numerical integrations of the Solar System reveal a remarkable stability of the orbits of the inner planets over billions of years, in spite of their chaotic variations characterized by a Lyapunov time of only 5 million years and the lack of integrals of
