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. ...

The ALPS project release 2.0: open source software for strongly correlated systems

Jean-David Picon

We present release 2.0 of the ALPS (Algorithms and Libraries for Physics Simulations) project, an open source software project to develop libraries and application programs for the simulation of strongly correlated quantum lattice models such as quantum ma ...

Superconductor–insulator transition in La2 − xSrxCuO4 at the pair quantum resistance

Davor Pavuna, Guy Joseph Günter Dubuis, Ivan Bozovic

High-temperature superconductivity in copper oxides arises when a parent insulator compound is doped beyond some critical concentration; what exactly happens at this superconductor–insulator transition is a key open question1. The cleanest approach is to t ...

Uncovering the Physics of Frustrated Quantum Magnets using the Correlation Density Matrix Approach

This work is devoted to the study, the development, and the application of a new systematic method yielding the dominant correlations that govern a quantum many-body state in an unbiased way. The dominant correlations between any two disjoint blocks of a s ...

Ground states and excitations of frustrated magnetic systems, from the classical limit to the quantum case

The first part of this thesis is devoted to classical magnetic systems. A method for an exhaustive search of states that do not break any spatial symmetry on a given lattice is presented. New Néel states on the kagome lattice are described. Their static st ...

Tailored-Potential Pyramidal Quantum Dot Heterostructures

Valentina Troncale

Semiconductor quantum dots are usually compared to artificial atoms, because their electronic structure consists of discrete energy levels as for natural atoms. These artificial systems are integrated in solid materials and can be localized with a spatial ...

Quantum distillation: Dynamical generation of low-entropy states of strongly correlated fermions in an optical lattice

Salvatore Manmana

Correlations between particles can lead to subtle and sometimes counterintuitive phenomena. We analyze one such case, occurring during the sudden expansion of fermions in a lattice when the initial state has a strong admixture of double occupancies. We pro ...

Exciton localization and diffusion in low-dimensional nanostructures formed on non-planar substrates

Nicolas Moret

Quantum wells (QWs), quantum wires (QWRs) and quantum dots (QDs) are semiconductor heterostructures with nanoscopic dimensions. At this length scale, their properties are governed by quantum mechanics. The interest in these nanostructures is motivated by a ...

The microcavity AC Stark triplet: Excitation in the exciton continuum

Benoît Marie Joseph Deveaud, Ursula Oesterle, Cristiano Ciuti, Michele Saba

The coherent optical response of high quality microcavities containing quantum wells is investigated. The dynamics of the ac Stark effect is investigated by degenerate pump-probe experiments, by exciting the quantum well excitons at various intensities and ...
