YbAl3C3 exhibits a spin gap formation due to spin dimer ground state below 10 K. In zero-field the ground state is paramagnetic and no sign of long range magnetic ordering down...

Our neutron scattering study on YbAl3C3 clearly reveals the presence of two well defined magnetic excitations at 1.5 and 3 meV at 4 K due to spin-dimer formation. Interestingly,...

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...
