Is Random Close Packing of Spheres Well Defined?

, 2000
Despite its long history, there are many fundamental issues concerning random packings of spheres that remain elusive, including a precise definition of random close packing (RCP).

Global assessment of the effectiveness of adaptation in coastal areas based on RCP/SSP scenarios

Climatic Change, 2019
The objective of this study is to assess the global impact of sea level rise and to evaluate the effectiveness of adaptation. Global areas of inundation due to sea level rise are identified.

Electro‐Active Metasurfaces Controlling Exceptional Topological Phase Through Low‐Voltage Operation on Conductive Polymer

Advanced Functional Materials, EarlyView.
This research investigates an electro‐active chiral optical response (EACOR)‐driven dual‐channel metasurfaces with fast electrical switching rates of 52 ms, and a low operating voltage of 0.5 V. The combination of polyaniline (PANI) thin film and the exceptional topological (ET) phase of chiral gold (Au) meta‐atoms modulate holographic images through ...

Scaling Behaviour of dN/dy in High-Energy Collisions

Universe
From a recently found family of analytic, finite and accelerating 1+1-dimensional solutions to perfect fluid relativistic hydrodynamics, we derive simple and powerful formulae to describe the rapidity and pseudorapidity density distributions.

Revival-collapse phenomenon in the fluctuations of quadrature field components of the multiphoton Jaynes-Cummings model

, 2009
In this paper we consider a system consisting of a two-level atom, initially prepared in a coherent superposition of upper and lower levels, interacting with a radiation field prepared in generalized quantum states in the framework of multiphoton Jaynes ...

Double Helical Plasmonic Antennas

Advanced Functional Materials, EarlyView.
Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.

Orbital Topology of Chiral Crystals for Orbitronics

Advanced Materials, EarlyView.
Chirality is ubiquitous in nature and constitutional for life. In chiral materials the intrinsic handedness, defined by their crystal structure, becomes a main driver for a novel electronic topology that is based on the orbital angular momentum rather than the electron spin.

On chemiluminescent emission from an infiltrated chiral sculptured thin film

, 2010
The theory describing the far-field emission from a dipole source embedded inside a chiral sculptured thin film (CSTF), based on a spectral Green function formalism, was further developed to allow for infiltration of the void regions of the CSTF by a ...
