Excitations, BEC, and partially ordered states of liquid 4He in disorder
We propose measurements of the elementary phonon-roton (p-r) excitations of liquid 4He confined in porous MCM-41 (45 Å pore diameter) at wave vectors Q ¿ beyond the roton¿, 2.4... -
Bose-Einstein Condensation in solid helium confined in porous media
We propose measurements of the Bose-Einstein Condensate (BEC) fraction n0 of solid helium confined in porous media. A superfluid fraction in solid helium in Vycor, in aerogel...
