EPJ D - Feshbach resonances in the 6Li-40K Fermi-Fermi mixture: Elastic versus inelastic interactions
- Details
- Published on 30 March 2011

(Cold Quantum Matter - EuroQUAM special issue)
Ultracold mixtures of two fermionic species hold great promise for synthesizing novel types of few and many-body quantum states. Magnetically tunable Feshbach resonances are the key to controlling the interaction in such systems. In this article in EPJD, Naik et al. present a state-of-the-art characterization of Feshbach resonances in the Fermi-Fermi mixture of 6Li-40K atoms, in particular concerning the interplay of both elastic and inelastic scattering.
EPJ D – Nanodroplets make perfect hosts

Helium nanodroplets provide a unique matrix for the spectroscopy of embedded atom species. In this recent paper in EPJD, Bünermann and Stienkemeier demonstrate a new model of how effects such as droplet shrinking, momentum transfer and cluster desorption affect the pick-up statistics of alkali atoms in helium nanodroplets.

EPJ E - Polymersomes made-to-measure

- Published on 22 March 2011
The use of polymersomes in drug delivery, medical imaging, micro-reactors or to mimic biophysical membrane phenomena is greatly dependent on the extent to which their properties can be controlled and tuned.
EPJ B - Solids under pressure

Constant-pressure molecular dynamics simulations allow the study of systems where external pressure is a driving force for a structural transformation.
Electrodeposition of an electroactive polymer and subsequent polymerization of monomers is a novel route to anchor polymer chains to electrode surfaces.
Tiny polymer droplets that crystallize on a surface are a shrewd expedient to study the birth of a polymer crystal by the elusive homogeneous nucleation mechanism. In most cases, take for example the dust particle in a snowflake, nucleation starts from a heterogenous defect. Homogenous nucleation is difficult to study because of the prevalence of defects in any bulk sample. Crystallization in small droplets alleviates this difficulty in a manner that is conceptually simple: subdivide the system into more domains than the number of defects. If the domains greatly outnumber the defects then only the homogenous mechanism can induce nucleation in a defect free compartment.
EPJ B - Geometry matters

A colloquium published in EPJ B provides a thorough formulation of the theory of the insulating state by means of geometrical concepts, which were somewhat hidden and implicit in the original literature.

The need to store, distribute and analyze the 15 million gigabytes of data annually generated by the Large Hadron Collider (LHC) at CERN has led to a revolutionary development of innovative software tools. Under CERN coordination, leading IT teams have tested and validated cutting-edge software technologies aimed to operate distributed computing and data storage infrastructures based on a worldwide network of hundreds of computing centers on an unprecedented scale.
EPJ B - Complexity Theory and the National Baseball Hall of Fame

- Published on 07 February 2011
Individual success in competitive endeavors, such as sports or academia, is the result of many factors, some of which are time-dependent. In order to compare human achievements from different time periods, we need to normalize success metrics so as to avoid a time-dependent bias in the comparison of the statistical measures. A novel 'detrending' approach presented in EPJ B removes precisely this bias and allows for an objective comparison across time.
