  Confinement has generally the effect of suppressing order in condensed
matter. Indeed, phase transitions such as freezing, or the superfluid
transition in liquid helium, occur at lower temperatures in confinement than
they do in the bulk. We provide here an illustration of a physical setting in
which the opposite takes place. Specifically, the enhancement of the superfluid
response of parahydrogen confined to nanoscale size cavities is demonstrated by
means of first principle computer simulations. Prospects to stabilize and
observe the long sought but yet elusive bulk superfluid phase of parahydrogen
in purposefully designed porous media are discussed.
