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

General Synthesis of Amorphous Pd‐Based Nanoparticles Towards Highly Efficient Nitrate‐to‐Ammonia Electrocatalysis

Advanced Functional Materials, EarlyView.
A family of amorphous palladium‐based multi‐component phosphides nanoparticles, synthesized via a robust one‐step wet‐chemical method, overcoming the immiscibility of different elements and the difficulty in forming a stable, disordered structure. When applied in the electrochemical nitrate reduction reaction, these nanocatalysts effectively suppress ...

Dynamical mirages: How bar-induced resonant trapping can mimic substructure clustering in dynamical parameter spaces

Astronomy & Astrophysics
Context. The complex task of unraveling the assembly history of the Milky Way evolves constantly, and new substructures are identified continuously. To properly validate and characterise the family of galactic progenitors, it is important to take all the

Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes

Advanced Functional Materials, EarlyView.
We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces

A Library of 77 Multibody Solar and Extrasolar Subsystems—A Review of Their Dynamical Properties, Global Mean-Motion Resonances, and the Landau-Damped Mean Tidal Fields

Astronomy
We revisit 77 relaxed (extra)solar multibody (sub)systems containing 2–9 bodies orbiting about gravitationally dominant central bodies. The listings are complete down to (sub)systems with 5 orbiting bodies and additionally contain 33 smaller systems with

Strength of higher-order spin-orbit resonances [PDF]

Physical Review E, 2004
When polarized particles are accelerated in a synchrotron, the spin precession can be periodically driven by Fourier components of the electromagnetic fields through which the particles travel. This leads to resonant perturbations when the spin-precession frequency is close to a linear combination of the orbital frequencies.

Toward Enhanced Inertial Sensing via Dynamically Soft Topological States in Piezoelectric Microacoustic Metamaterials

Advanced Functional Materials, EarlyView.
A piezoelectric microacoustic wave device exploiting topologically protected interface states with significantly higher dynamic compliance than Lamb or Rayleigh modes achieves record‐high out‐of‐plane particle velocities exceeding 51 m/s. These findings indicate that leveraging topological interface states can overcome key limitations of piezoelectric ...

Classifying Orbits of Low and High Energy Stars in Axisymmetric Disk Galaxies

Open Astronomy, 2016
The ordered or chaotic character of orbits of stars moving in the meridional (R, z) plane of an analytic axisymmetric time-independent disk galaxy model with an additional spherically symmetric central nucleus is investigated. Our aim is to determine how

Confirming Resonance in Three Transiting Systems

The Astronomical Journal, 2023
Although resonant planets have orbital periods near commensurability, resonance is also dictated by other factors, such as the planets’ eccentricities and masses, and therefore must be confirmed through a study of the system’s dynamics.
