Electron quantization in arbitrarily shaped gold islands on MgO thin films

Wolf-Dieter Schneider

Low-temperature scanning tunneling microscopy has been employed to analyze the formation of quantum well states (QWS) in two-dimensional gold islands, containing between 50 and 200 atoms, on MgO thin films. The energy position and symmetry of the eigenstat ...

Surface morphology of MnSi thin films grown on Si(111)

Klaus Kern, Theresa Lutz, Giovanni Costantini

The surface morphology of MnSi thin films grown on Si(111)-7 x 7 substrates was investigated by systematically changing the amount of deposited Mn. A new 3 x 3 surface reconstruction was found at the very initial growth stages, whose atomic configuration w ...

Structure of active dimeric human telomerase

Joachim Lingner

Telomerase contains a large RNA subunit, TER, and a protein catalytic subunit, TERT. Whether telomerase functions as a monomer or dimer has been a matter of debate. Here we report biochemical and labeling data that show that in vivo-assembled human telomer ...

Optimal antibunching in passive photonic devices based on coupled nonlinear resonators

Vincenzo Savona

We propose the use of weakly nonlinear passive materials for prospective applications in integrated quantum photonics. It is shown that strong enhancement of native optical nonlinearities by electromagnetic field confinement in photonic crystal resonators ...

Scanning tunneling microscopy at multiple voltage biases of stable “ring-like” Ag clusters on Si(111)–(7×7)

Corsin Battaglia, Laure-Emmanuelle Perret Aebi, Philipp Aebi

Since more than twenty years it is known that deposition of Ag onto Si(111)–(7×7) leads under certain conditions to the formation of so-called “ring-like” clusters, that are particularly stable among small clusters. In order to resolve their still unknown ...

Interface-confined mixing and buried partial dislocations for Ag bilayer on Pt(111)

Harald Brune, Daniele Passerone

The trigonal strain-relief pattern formed by an Ag bilayer on Pt(111) is a prominent example for dislocation networks and their use as nanotemplates. However, its atomic structure has not been solved. Combining scanning tunneling microscopy, low-energy ion ...

Equivalence of synthesis and atomic formulations of sparse recovery

Volkan Cevher, Mitra Fatemi, Shayan Dashmiz

Recovery of sparse signals from linear, dimensionality reducing measurements broadly fall under two well-known formulations, named the synthesis and the analysis a ́ la Elad et al. Recently, Chandrasekaran et al. introduced a new algorithmic sparse recover ...

A new approach to plasma profile control in ITER

Jonathan Bryan Lister, Sun Hee Kim

Advanced tokamak operation in ITER, such as the steady-state and hybrid modes, requires an active realtime feedback control of plasma profiles to achieve the advanced regimes for sustained operation. In this work, we have explored a potentially robust cont ...
