1. Modeling mesoscopic unconventional superconductors
Abstract : High-temperature superconducting materials are often experimentally realized as thin films that can be patterned into devices operating in the mesoscopic regime. On this length scale, various finite-size and surface effects heavily influence the nature of the superconducting state, and can induce new ground states with spontaneously broken symmetries.

2. Mesoscopic phenomena in hybrid superconductor/ferromagnet structures
Abstract : This thesis explores peculiar effects of mesoscopic structures revealed at low temperatures. Three particular systems are studied experimentally: Ferromagnetic thin films made of diluted Pt1-xNix alloy, hybrid nanoscale Nb-Pt1-xNix-Nb Josephson junctions, and planar niobium Josephson junction with barrier layer made of Cu or Cu0.47Ni0.53 alloy.

3. Thermoelectric Effects and Single Electron Sources in Mesoscopic Transport; a Scattering Approach
Abstract : This thesis concerns the theoretical analysis of thermoelectric transport properties and single electron sources in mesoscopic conductors. Wepropose two types of thermoelectric heat engines and analyze them with thehelp of performance quantifiers. READ MORE

4. Charge and Energy Noise from On-demand Electron Sources
Abstract : On-demand single electron sources (SES) are of key importance for future electronic applications such as metrology or quantum optics with electron. They allow for achieving a controlled, low-fluctuations flow of particles in a coherent mesoscopic conductor. READ MORE

5. Transport in mesoscopic superconducting devices
Abstract : A field of growing interest within the last few decades is the study of superconductivity in mesoscopic-scale heterostructures. Mesoscopic refers to sizes between the atomic and macroscopic scales. READ MORE
