Frequency-dependent Study of Solid Helium-4 Contained in a Rigid Double-torus Torsional Oscillator
Jaewon Choi, Jaeho Shin, Euseong Kim
The rigid double-torus torsional oscillator (TO) is constructed to reduce any elastic effects in-herent to complicate TO structures, allowing explicit probing for a genuine superso…
Superfluid-like TO Responses in Rotating Solid Helium
Jaewon Choi, Tomoya Tsuiki, Daisuke Takahashi +4
The irrotational nature of superfluid helium was discovered through its decoupling from the container under rotation. Similarly, the resonant period drop of a torsional oscillator…
Simultaneous investigation of shear modulus and torsional resonance of solid 4He
Jaeho Shin, Jaewon Choi, Keiya Shirahama +1
We investigate the origin of a resonant period drop of a torsional oscillator (TO) containing solid He by inspecting its relation to a change in elastic modulus. To underst…
Microscopic description of stress- and temperature-dependent shear modulus in solid 4He
Evan S. H. Kang, Hongkee Yoon, Eunseong Kim
We developed a detailed microscopic method that describes the shear modulus anomaly of solid helium at low temperature. The shear modulus was calculated using the pinning length of…
Non-Classical Response from Quench-Cooled Solid Helium Confined in Porous Gold
D. Y. Kim, S. Kwon, H. Choi +2
We have investigated the non-classical response of solid 4He confined in porous gold set to torsional oscillation. When solid helium is grown rapidly, nearly 7% of the solid helium…
