The influence of interactions on electronic transport properties can be observed in many nanostructures, in particular in a so-called quantum dot, namely a spatially isolated island in and out of which electrons can tunnel. Due to its small size, the quantum dot supports discretely-spaced energy levels; considering only one of these levels for simplicity, we model the dot with the Hamiltonian H...

We present measurements of relative intensity noise versus various levels of optical feedback for 1.3 μm quantum dot lasers epitaxially grown on silicon for the first time. A systematic comparison is made with heterogeneously integrated 1.55 μm quantum well lasers on silicon. Our results indicate up to 20 dB reduced sensitivity of the quantum dot lasers on silicon compared to the quantum wells.

The focus of our effort has been to develop quantum information processing technologies based on a solid-state cavity QED platform consisting of quantum dots in photonic crystals. The main goals that we have accomplished include: 1. Study of the ultrafast dynamics of the quantum dot-cavity QED system [Majumdar et al., Phys. Rev. A, 2012], and ultrafast switching between two single photon pulses...

We calculate the frequency-dependent admittance of a phase-biased Josephson junction spanning magnetic impurity or spinful Coulomb-blockaded quantum dot. The local moment gives rise to Yu-Shiba-Rusinov bound states, which govern subgap absorption as well inductive response. model system by superconducting spin-polarized exchange-cotunnel and linear current response an ac bias voltage, including...

Quantum dot fluorophores provide a photo and bio-stable optical marker signal well suited to the tracking of lineage within large cell populations over multiple generations. We have used a Monte Carlo algorithm to model the process of dot partitioning and dilution by cell mitosis. A Genetic Algorithm was used to compare simulated and experiment quantum dot distributions, which shows that the do...

Semiconductor-based quantum structures integrated into mechanical resonators have emerged as a unique platform for generating entanglement between macroscopic phononic and mesocopic electronic degrees of freedom. A key challenge to realizing this is the ability to create and control the coupling between two vastly dissimilar systems. Here, such coupling is demonstrated in a hybrid device compos...

Fluctuating asymmetry is an estimate of developmental stability and, in some cases, the asymmetry of morphological traits can reflect aspects of individual fitness. As asymmetry can be a marker for fitness, it has been proposed that organisms could use morphological asymmetry as a direct visual cue during inter- and intraspecific encounters. Despite some experimental evidence to support this pr...
