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…
Superconducting gap structure of the 115's revisited
F. Ronning, Jian-Xin Zhu, Tanmoy Das +4
Density functional theory calculations of the electronic structure of Ce- and Pu-based heavy fermion superconductors in the so-called 115 family are performed. The gap equation is…
The Influence Of Elastic Deformations On The Supersolid Transition
T. Arpornthip, A. V. Balatsky, M. Graf +1
We study, within the Ginzburg-Landau (GL) theory of phase transitions, how elastic deformations in a supersolid lead to local changes in the supersolid transition temperature. The…
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…
Electronic Duality in Strongly Correlated Matter
T. Park, M. J. Graf, L. Boulaevskii +2
Superconductivity develops from an attractive interaction between itinerant electrons that creates electron pairs which condense into a macroscopic quantum state--the superconducti…
Entropy of solid He4: the possible role of a dislocation glass
A. V. Balatsky, M. J. Graf, Z. Nussinov +1
Solid He4 is viewed as a nearly perfect Debye solid. Yet, recent calorimetry indicates that its low-temperature specific heat has both cubic and linear contributions. These feature…
The nuclear spin-lattice relaxation rate in the PuMGa materials
Yunkyu Bang, M. J. Graf, N. J. Curro +1
We examine the nuclear spin-lattice relaxation rates of PuRhGa and PuCoGa, both in the superconducting and normal states, as well as their Knight shifts. Results fo…
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…
