Superfluid Hydrogen In Nanoscale Confinement

• 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.
