Weak Coupling Effects in helium-4
TECHNICAL<br/>For a system near a continuous phase transition, the behavior of many thermodynamic properties arises from the growth of the correlation length. This length diverges in the thermodynamic limit and is ...
Confinement Effects at the Superfluid Transition of 4He
9623831 Gasparini Usually one deals with systems where the spatial dimension is not a relevant variable in the thermodynamic behavior. That is, systems half as large or twice as large behave identically when normalized by ...
Critical and Hydrodynamic Effects in Confined Helium
Most Materials to which one is accustomed are infinite in size and three-dimensional in character. By this it is meant that their special dimensions extend over distances, in all directions, which are much larger than ...
Finite-size Scaling of Four Helium Near the Superfluid Transition and Two-Dimensional Behavior of Three Helium in Four Helium Films
Liquid helium displays a number of interesting properties at low temperatures. Some are unique to this quantum fluid, others are common to other systems, but observable with a higher degree of precision in helium. They ...
Weak Links and Proximity Effects in Microstructures of He-4
*****NON-TECHNICAL ABSTRACT*****<br/>This low temperature physics project has the goal of understanding how a system undergoing a phase transformation can be influenced by a nearby system undergoing the same ...
Dimensionality and Weak-links Effects at the Superfluid Transition of 4He
This low-temperature physics research project will investigate the superfluid transition of confined 4He as a paradigm of critical behavior. The work is intended to test theories of finite-size scaling at a second order ...
