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. 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

4. Tailoring the magnetic order in mesoscopic spin systems
Abstract : Mesoscopic spin systems can be designed and fabricated using modern nano-fabrication techniques. These systems can contain large numbers of patterned ferromagnetic elements, for which the shape will generally determine their effective mesospin dimensionality. READ MORE

5. 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
