Phenomenology of 10(32) dark sectors

We postulate an exact permutation symmetry acting on 10(32) standard model copies as the largest possible symmetry extension of the standard model. This setup automatically lowers the fundamental gravity cutoff down to TeV, and thus, accounts for the quant ...

Absolute and high precision 3 degrees of freedom position sensor

Reymond Clavel, Florent Cosandier

We present a compact 3 degrees of freedom (dof) (X-Y-θz) absolute position sensor offering a sub-micrometric resolution. The travelling range is 15x15mm2 (translations) and ±180° (rotation), with an absolute precision better than 10μm over the whole travel ...

Discontinuous Galerkin method for computing gravitational waveforms from extreme mass ratio binaries

Jan Sickmann Hesthaven

Gravitational wave emission from extreme mass ratio binaries (EMRBs) should be detectable by the joint NASA-ESA LISA project, spurring interest in analytical and numerical methods for investigating EMRBs. We describe a discontinuous Galerkin (dG) method fo ...

Black hole bound on the number of species and quantum gravity at CERN LHC

Michele Redi

In theories with a large number N of particle species, black hole physics imposes an upper bound on the mass of the species equal to M-Planck/root N. This bound suggests a novel solution to the hierarchy problem in which there are N approximate to 10(32) g ...

The theta parameter in loop quantum gravity: effects on quantum geometry and black hole entropy

Danilo Jimenez Rezende

The precise analog of the theta-quantization ambiguity of Yang-Mills theory exists for the real SU(2) connection formulation of general relativity. As in the former case theta labels representations of large gauge transformations, which are super-selection ...

Modeling of gain and phase dynamics in quantum dot amplifiers

Benoît Marie Joseph Deveaud, Marco Rossetti, Pablo Moreno

By means of an electron hole rate equation model we explain the phase dynamics of a quantum dot semiconductor optical amplifier and the appearance of different decay times observed in pump and probe experiments. The ultrafast hole relaxation leads to a fir ...

Gravity Cutoff in Theories with Large Discrete Symmetries

Sergey Sibiryakov, Michele Redi

We set an upper bound on the gravitational cutoff in theories with exact quantum numbers of large N periodicity, such as Z(N) discrete symmetries. The bound stems from black hole physics. It is similar to the bound appearing in theories with N particle spe ...

Magneto-photoluminescence of heavy- and light-hole excitons in site-controlled pyramidal quantum dots

Elyahou Kapon, Alok Rudra, Daniel Oberli

Pyramidal, site-controlled InGaAs/AlGaAs quantum dots (QDs) are studied by micro-photoluminescence (PL) spectroscopy in a magnetic field. The light-hole (LH) excitonic transitions exhibit diamagnetic shifts similar to those of their heavy-hole (HH) counter ...

Mechanical characterization of a dielectric elastomer microactuator with ion-implanted electrodes

Herbert Shea, Samuel Rosset, Muhamed Niklaus

We report on the mechanical characterization and modeling of a non-prestretched dielectric elastomer diaphragm microactuator with ion-implanted electrodes under the influence of a distributed load (pressure). Thin polydimethysiloxane (PDMS) membranes (30 u ...

All-Optical Manipulation of Electron Spins in Carbon-Nanotube Quantum Dots

Christophe Marcel Georges Galland

We demonstrate theoretically that it is possible to manipulate electron or hole spins all optically in semiconducting carbon nanotubes. The scheme that we propose is based on the spin-orbit interaction that was recently measured experimentally; we show tha ...
