Abstract

Confinement is known to suppress order in condensed matter. This is well exemplified in phase transitions such as freezing, as well as the superfluid transition in liquid helium, which occur at lower temperatures in confinement than in the bulk. We provide in this thesis a demonstration of a physical setting in which the reverse takes place. Particularly, the enhancement of the superfluid response of parahydrogen confined to nanoscale size cavities is illustrated by means of first principle computer simulations. Prospects to stabilize and observe the long investigated but yet elusory bulk superfluid phase of parahydrogen in objectively designed porous media are discussed.
