The enigma of supersolidity
S Balibar - Nature, 2010 - nature.com
A'supersolid'is a quantum solid in which a fraction of the mass is superfluid. As a remarkable
consequence, it is rigid, but part of its mass is able to flow owing to quantum physical …

Supersolidity and disorder
A solid is called'supersolid'if it exhibits superfluid properties. Supersolidity is a paradoxical
phenomenon whose understanding has become a major challenge since 2004, when Kim …

Evidence for a Superglass State in Solid 4He
Although solid helium-4 (4He) may be a supersolid, it also exhibits many phenomena
unexpected in that context. We studied relaxation dynamics in the resonance frequency f (T) …

Frequency dependence and dissipation in the dynamics of solid helium
Torsional oscillator experiments on solid He 4 show frequency changes which suggest mass
decoupling, but the onset is broad and is accompanied by a dissipation peak. We have …

Nonsuperfluid Origin of the Nonclassical Rotational Inertia in a Bulk Sample of Solid
JD Reppy - Physical review letters, 2010 - APS
The torsional oscillator experiments described here examine the effect of disorder on the
nonclassical rotational inertia (NCRI) of a solid He 4 sample. The NCRI increases with …

Intrinsic and dislocation-induced elastic behavior of solid helium
Recent experiments showed that the shear modulus of solid H 4 e stiffens in the same
temperature range (below 200 mK) where mass decoupling and supersolidity have been …

Effect of elasticity on torsional oscillator experiments probing the possible supersolidity of helium
HJ Maris - Physical Review B—Condensed Matter and Materials …, 2012 - APS
We consider the effect of elasticity on torsional oscillator experiments to investigate the
possible supersolidity of helium. We show that in most, and possibly all torsional oscillators …
