Threefold reduction in thermal conductivity of Vycor glass due to adsorption of liquid 4He
We report thermal conductivity measurements of porous Vycor glass when it is empty and when the pores are filled with helium between 0.06 and 0.5 K. The filling of liquid ^3 He and liquid ^4 He inside the Vycor pores brings about two to three-fold reduction of the thermal conductivity as compared wi...
