Supraleitung und Tieftemperaturphysik 2

What it is about

The module covers fundamentals and current topics of superconductivity, quantum fluids, mesoscopic solid-state systems and experimental low-temperature techniques. You will learn to understand and apply phenomena such as Bose-Einstein condensation, superfluidity of He-3/He-4, quantum interference effects in nanostructures, and methods for generating and measuring very low temperatures.

What you will be able to do

• Identify differences between classical and quantum fluids
• Describe the transition from classical to quantum fluidity when lowering the temperature
• Explain the influence of quantum statistics (bosons vs. fermions)
• Illustrate the derivation and estimation of the Bose-Einstein condensation temperature
• Name and explain properties of superfluid He-4 and He-3
• Name and apply characteristic length and time scales in charge transport in mesoscopic conductors
• Describe the effects of quantum interference phenomena (e.g., weak localization, universal conductance fluctuations) on transport
• Name and explain methods for generating and measuring low temperatures and their physical foundations
