Defects and glassy dynamics in solid He-4: Perspectives and current status
A. V. Balatsky, M. J. Graf, Z. Nussinov +1
We review the anomalous behavior of solid He-4 at low temperatures with particular attention to the role of structural defects present in solid. The discussion centers around the p…
The glassy response of solid He-4 to torsional oscillations
M. J. Graf, Z. Nussinov, A. V. Balatsky
We calculated the glassy response of solid He-4 to torsional oscillations assuming a phenomenological glass model. Making only a few assumptions about the distribution of glassy re…
Torsional oscillators and the entropy dilemma of putative supersolid He-4
M. J. Graf, A. V. Balatsky, Z. Nussinov +2
Solid He-4 is viewed as a nearly perfect Debye solid. Yet, recent calorimetry measurements by the PSU group (J. Low Temp. Phys. 138, 853 (2005) and Nature 449, 1025 (2007)) indicat…
Strong electron-phonon coupling in delta-phase stabilized Pu
M. J. Graf, T. Lookman, J. M. Wills +2
Heat capacity measurements of the delta-phase stabilized alloy Pu-Al suggest that strong electron-phonon coupling is required to explain the moderate renormalization of the electro…
