Cavity Optomechanics: Cooling of a Micromechanical Oscillator into the Quantum Regime

Tobias Kippenberg, Albert Schliesser, Emanuel Gavartin, Stefan Alexander Weis

Using optical sideband cooling, a micromechanical oscillator is cooled to a phonon occupancy below 10 phonons, corresponding to a probability of finding it in its quantum ground state more than 10% of the time. ...

Communications: Evaluation of the nondiabaticity of quantum molecular dynamics with the dephasing representation of quantum fidelity

Jiri Vanicek, Tomas Zimmermann

We propose an approximate method for evaluating the importance of non-Born–Oppenheimer effects on the quantum dynamics of nuclei. The method uses a generalization of the dephasing representation (DR) of quantum fidelity to several diabatic potential energy ...

Nanophotonic technologies for single-photon devices

Laurent Balet, Francesco Marsili, Alessandro Gaggero

The progress in nanofabrication has made possible the realization of optic nanodevices able to handle single photons and to exploit the quantum nature of single-photon states. In particular, quantum cryptography (or more precisely quantum key distribution, ...

Single Photons from Coupled Quantum Modes

Vincenzo Savona, Timothy Chi Hin Liew

Single photon emitters often rely on a strong nonlinearity to make the behavior of a quantum mode susceptible to a change in the number of quanta between one and two. In most systems, the strength of nonlinearity is weak, such that changes at the single qu ...

Determination of the atmospheric neutrino flux and searches for new physics with AMANDA-II

Shirit Cohen, Mathieu Ribordy, Levent Demirörs, Xiaoxia Bai

The AMANDA-II detector, operating since 2000 in the deep ice at the geographic South Pole, has accumulated a large sample of atmospheric muon neutrinos in the 100 GeV to 10 TeV energy range. The zenith angle and energy distribution of these events can be u ...

Efficient evaluation of accuracy of molecular quantum dynamics using dephasing representation

Jiri Vanicek, Cesare Mollica

Ab initio methods for the electronic structure of molecules have reached a satisfactory accuracy for calculations of static properties but remain too expensive for quantum dynamics calculations. We propose an efficient semiclassical method for evaluating t ...

Investigation into the coupling of quantum dots to photonic crystal nanocavities at telecommunication wavelengths

Laurent Balet

Recently, the emission of single photons with emission wavelength in the 1.3 µm telecommunication window was demonstrated for InAs quantum dots. This makes them strong candidates for applications such as quantum cryptography, and in a longer term, quantum ...

Compositional verification for component-based systems and application

Joseph Sifakis

We present a compositional method for the verification of component-based systems described in a subset of the BIP language encompassing multi-party interaction without data transfer. The method is based on the use of two kinds of invariants. Component inv ...

Hyperfine interactions in graphene and related carbon nanostructures

Oleg Yazyev

Hyperfine interactions, magnetic interactions between the spins of electrons and nuclei, in graphene and related carbon nanostructures are studied. By using a combination of accurate first principles calculations on graphene fragments and statistical analy ...
