The course will have lecture components that introduce both experimental
and theoretical ideas in low temperature physics. The remaining hours
will involve hands on experience in designing and experiments in the
ultra low temperature laboratory.
- liquefaction of helium and properties of liquid helium including
phenomena like super-fluidity , second sound, phenomenological two
fluid theories. Landau theory of quasi-particles, vortices and
quantization of circulation
- Properties of Helium 3 and Helium3 helium 4 mixtures
- Solid state systems below 4.2K ( mainly acoustic , thermal and
electronic properties )
- Overview of topics like super-conductivity spin glasses
- Tehcniques below 4.2K , Adiabatic demagnetization , principles
of helium3 helium 4 refrigeration, nuclear demagnetization techniques
to reach temperatures below 1mK
- Electronics and instrumentation below 4.2K examples like discovery
of cosmic microwave background (CMB) using cryogenic amplifiers
- Low temperature thermometry including modern techniques like
coulomb blockade primary thermometry
- Modern cryofree techniques to reach below 10 K .
