Loss-enabled sub-Poissonian light generation in a bimodal nanocavity

We propose an implementation of a source of strongly sub-Poissonian light in a system consisting of a quantum dot coupled to both modes of a lossy bimodal optical cavity. When one mode of the cavity is resonantly driven with coherent light, the system will act as an efficient photon number filter, and the transmitted light will have a strongly sub-Poissonian character. In addition to numerical simulations demonstrating this effect, we present a physical explanation of the underlying mechanism. In particular, we show that the effect results from an interference between the coherent light transmitted through the resonant cavity and the super-Poissonian light generated by photon-induced tunneling. Peculiarly, this effect vanishes in the absence of the cavity loss

Oil Management and the Resource Curse in Ghana: the role of civil society

The so-called ‘Resource curse’ has manifested in several resource rich countries in the African continent. When Ghana found oil in 2007, the finding was consequently accompanied by high hopes of economic growth and increased social welfare (blessing), but also fear that they oil would increase corruption and political patronage (curse). The resource curse literature identifies extensive checks and balances on the governing elite as necessary for overcoming the resource curse, and an active civil society is assumed to play an important part in this. Through qualitative interviews with civil society actors, this thesis aims to understand the role played by civil society in the management of Ghana’s oil resources. The thesis concludes that while democracy in Ghana cannot ensure that the country escapes the resource curse, it has allowed the emergence of a vibrant civil society with real political space and legitimacy. Oil governance in the country however, lacks important oversight structures, partly due to gaps in the legislative framework, and partly due to executive dominance in Ghana’s political life. This complicates civil society’s role to monitor oil sector activity, and consequently to play the important role identified by the literature: to hold their leaders accountable

Phonon-mediated coupling between quantum dots through an off-resonant microcavity

We present experimental results showing phonon-mediated coupling between two quantum dots embedded inside a photonic crystal microcavity. With only one of the dots being spectrally close to the cavity, we observe both frequency up-conversion and down-conversion of the pump light via a $\sim1.2$ THz phonon. We demonstrate this process for both weak and strong regimes of dot-cavity coupling, and provide a simple theoretical model explaining our observations

The residential pattern of military personnel associated with Offutt Air Force Base, Nebraska, 1970

A particular method of inspecting data is known to all scholars as the geographic method, based on charting the limits or range of phenomena, features, or traits that have a localized distribution on the earth. Geographers have long been concerned with the distribution of phenomena, whether they be species of trees, refugees, cities, land use, resources, glaciers, farms, ethnic groups, religions, or a myriad of other examples, and distributional analyses are fundamental to the discipline of geography. During the infancy of geography as a discipline, the studies of distributions were mainly descriptive, but as the subject grew and became, more sophisticated, comparison with other patterns and explanation became important. As Taaffe has noted, the geographer still describes and analyzes patterns found on maps, but behavior and process are becoming important considerations. This paper, too, is designed to study the patterns found on maps, that is, the residential patterns associated with the military personnel of Offutt Air Force Base, Nebraska, Process is also one of the considerations

Navigating Research Waters: The Research Mentor Program at the University of New Hampshire at Manchester

This essay uses a journal format to describe the research mentor program at the University of New Hampshire at Manchester (UNHM). Librarians, Learning Center staff, and writing instructors at UNHM have collaborated to train class-linked tutors to present basic library instruction in the classroom and to provide one-on-one research assistance to students in freshman-level composition classes. This information literacy initiative has expanded our students\u27 community of learning by providing them with point-of-need research assistance from knowledgeable peers
