Shear modulus in viscoelastic solid He
Jung-Jung Su, Matthias J. Graf, Alexander V. Balatsky
The complex shear modulus of solid He exhibits an anomaly in the same temperature region where torsion oscillators show a change in period. We propose that the observed stiffen…
A glass anomaly in the shear modulus of solid He
Jung-Jung Su, Matthias J. Graf, Alexander V. Balatsky
The shear modulus of solid He exhibits an anomalous change of order 10%[1, 2] at low temperatures that is qualitatively similar to the much smaller frequency change in torsiona…
A glassy contribution to the heat capacity of hcp He solids
Jung-Jung Su, Matthias J. Graf, Alexander V. Balatsky
We model the low-temperature specific heat of solid He in the hexagonal closed packed structure by invoking two-level tunneling states in addition to the usual phonon contribut…
