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 ...
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 ...
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 ...
Confinement and Scaling of 4He at the Superfluid Transition
9972287<br/>Gasparini<br/><br/>This is a condensed matter physics project employing micro-scale cells to investigate the critical behavior of helium-4. Properties of a system which is small on a relevant ...
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 ...
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 ...
