Abstract:

Ultra-cold atoms in optical lattices provide a versatile and robust platform to study fundamental condensed-matter physics problems and have applications in quantum optics as well as quantum information processing. For many of these applications, Rydberg atoms (atoms excited to large principal quantum numbers) are ideal due to its long coherence times and strong interactions. However, one of the pre-requisite for such applications is identical confinement of ground state atoms with Rydberg atoms. This is challenging for conventionally used alkali atoms. In this thesis, I discuss the potenti

Abstract:

<p> Aerosols affect the radiation budget of the earth-atmosphere system by directly reflecting or absorbing solar radiation and also indirectly, by altering the cloud albedo through changes in the cloud condensation nuclei concentration (CCN). Increases in CCN concentrations result in an increase in the cloud droplet number concentration (N). Assuming the cloud liquid water content (LWC) stays the same, this will result in smaller cloud droplet sizes. Thus, this will increase cloud reflectance and cloud lifetime as cloud cover also increases. An accurate quantification of the aerosol forcing e

Crop management practices, such as soil tillage and crop residue management, are land management activities with potentially large impacts on carbon (C) cycling and climate at the global scale. Improvements in crop management practices, such as conservation tillage or 'no-till' (NT), have been proposed as climate change mitigation measures because such practices may alter C cycles through increased sequestration of soil C in agricultural soils. Despite their potential importance, regional to global scale data are lacking for many crop management practices, and few studies have evaluated the po

Landscapes evolve in a complex interplay between climate and tectonics. Thus, the geomorphic characteristics of a landscape can only be understood if both, climatic and tectonic signals of past and ongoing processes can be identified.

The Cenozoic Andes are an ideal setting to evaluate tectonic and climatic aspects of landscape evolution at different time and length scales in different natural compartments.

Abstract:

En période de crue, le rejet d'eaux de drainage dans les émissaires à surface libre apparaît comme une cause possible de formation d'inondations, car il introduit dans le réseau hydrographique des eaux qui auraient pu circuler de manière diffuse en l'absence de drainage (infiltration ou ruissellement). Il apparaît aussi comme une source de pollution du milieu naturel, en déversant des nutriments ou certains traitements phytosanitaires lessivés. Les modifications liées à la présence du drainage sont cependant difficiles à évaluer.En revanche, le rôle du réseau d'émissaires peut être mieux évalu

Abstract:

L'Islande constitue la partie émergée d'un plateau basaltique qui s'est formé par interférence entre la dorsale médio-Atlantique et un point chaud dans l'Atlantique Nord. Une calotte glaciaire s'est installée à plusieurs reprises durant le Quaternaire sur ce plateau. L'étude de la structure et de la morphologie de l'Islande permet donc de préciser les interactions entre trois processus géodynamiques : extension lithosphérique liée à l'accrétion océanique, anomalie thermique liée au point chaud et dynamique glaciaire. Une analyse structurale montre que l'Islande est formée de plusieurs systèmes

Abstract:

Landslides are one of the biggest natural hazards in Georgia, a mountainous country in the Caucasus. So far, no systematic monitoring and analysis of the dynamics of landslides in Georgia has been made. Especially as landslides are triggered by extrinsic processes, the analysis of landslides together with precipitation and earthquakes is challenging. In this thesis I describe the advantages and limits of remote sensing to detect and better understand the nature of landslide in Georgia. The thesis is written in a cumulative form, composing a general introduction, three manuscripts and a summary

Master of Science<br>Department of Geology<br>Sambhudas Chaudhuri<br>The exploration and development of unconventional shale plays provide an opportunity to study the hydrocarbon generation process. These unconventional plays allow one to investigate the interactions between the fluid, mineral, and organic material that occur in a hydrocarbon-generating source bed, before any changes in composition that may occur during secondary migration or post migration processes. Previous studies have determined the chemical constituents of formation waters collected from conventional reservoirs after sec

Abstract:

Afin d'appréhender in-situ le couplage entre les pressions de fluides et la mécanique des failles, un laboratoire géodynamique a été installé dans le Rift de Corinthe. L'élément majeur de ce projet européen est un forage recoupant la faille d'Aigion, qui a rejoué lors d'un séisme de magnitude 6.2 en 1995, et son instrumentation permanente qui permet le suivi en continu de la pression de fluide autour de la faille. Nous avons d'abord caractérisé l'environnement hydrogéologique par la conjonction de méthodes relevant de la thermique et de l'hydrogéologie. Il devient alors possible d'interpréter
