Orbital stability of compact three-planet systems
Astronomy & AstrophysicsContext. 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
Physical Review X, 2023 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

Exchange‐Coupled Two‐Dimensional MOFs
Advanced Functional Materials, EarlyView.Graphene mediates ferromagnetic coupling between two‐dimensional metal‐organic frameworks and cobalt. Fe‐tetracyanobenzene develops a remanent magnetic response whose orientation follows the cobalt magnetization direction and persists up to room temperature, whereas Ni‐TCNB remains only field‐polarized.

Orbital symmetry fingerprints for magnetic adatoms in graphene
New Journal of Physics, 2014 In this paper, we describe the formation of local resonances in graphene in the presence of magnetic adatoms containing localized orbitals of arbitrary symmetry, corresponding to any given angular momentum state. We show that quantum interference effects

Census of transient orbital resonances encountered during binary inspiral
, 2013 Transient orbital resonances have recently been identified as potentially important to the inspiral of small bodies into large black holes. These resonances occur as the inspiral evolves through moments in which two fundamental orbital frequencies, Ω ...

Advanced Functional Materials, EarlyView.Ultra‐narrow green multi‐resonance thermally activated delayed fluorescence emitters have been developed by linear π‐extension strategy using tetracyclic naphtho[2,3‐b]benzofuran unit. The resulting phosphorescence‐sensitized OLEDs achieve a maximum external quantum efficiency of 37.7% in the bottom‐emitting architecture, while the complementary top ...

On the impact of a radiational open boundary condition on continental shelf resonances [PDF]
, 2013 Studies carried out with a one-dimensional model of a continental shelf and deep ocean have shown that the use of a radiational boundary condition doubles the decay rate of the shelf resonances.
