1. Quantum Correlations and Temperature Fluctuations in Nanoscale Systems
Sammanfattning : This thesis addresses two different topics related to the physics of nanoscale systems. The first topic concerns quantum correlations and entanglement between electrons in solid-state systems, with a focus on how to generate electronic orbital entanglement on a sub-decoherence time scale and how to achieve experimentally more feasible entanglement detection schemes.

2. Nanoscale structure forming processes : Metal thin films grown far-from-equilibrium
Sammanfattning : Thin film growth from the vapor phase has for a long time intrigued researchers endeavouring to unravel and understand atomistic surface processes that govern film formation. Their motivation has not been purely scientific, but also driven by numerous applications where this understanding is paramount to knowledge-based design of novel film materials with tailored properties.

3. Fluctuations and nonequilibrium thermodynamics in electronic nanosystems
Sammanfattning : In the last decades thermodynamics has seen a resurgence because of the interesting phenomena that happen in small-scale systems. Indeed, in nanoscale devices, quantum effects and fluctuations cannot generally be neglected and influence both the transport and their thermodynamic performance. LÄS MER
4. There Is an Alloy at the End of the Rainbow: Structure and Optical Properties From Bulk to Nano
Sammanfattning : Mixing different chemical species and decreasing dimensions to the nanoscale are two powerful approaches for improving materials. In both cases new properties emerge, and structure, composition, and chemical ordering can be tuned to tailor materials for specific purposes. LÄS MER
5. Heat control in mesoscopic conductors - exploiting quantum effects and size confinement
Sammanfattning : This thesis deals with a theoretical analysis of heat currents, their exploitation and their control in nanoscale devices. The motivation for this study is twofold. (i) The development of nanoscale devices sets up the basis of many applications ranging from nanoelectronics to quantum technology. LÄS MER
