Evolutionary search for new high-k dielectric materials: methodology and applications to hafnia-based oxides
Qingfeng Zeng, Artem R. Oganov, Andriy O. Lyakhov +6
High-k dielectric materials are important as gate oxides in microelectronics and as potential dielectrics for capacitors. In order to enable computational discovery of novel high-k…
The glassy response of double torsion oscillators in solid Helium-4
Matthias J. Graf, Jung-Jung Su, Hari P. Dahal +2
Single and double torsion oscillators have been used successfully to measure the anomalous change in resonant frequency and accompanying dissipation in solid He-4. We present a gla…
Optimal control of the local electromagnetic response of nanostructured materials: optimal detectors and quantum disguises
Ilya Grigorenko, Herschel Rabitz, Alaxander Balatsky
We consider the problem of optimization of an effective trapping potential in a nanostructure with a quasi-one-dimensional geometry. The optimization is performed to achieve certai…
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…
