91. Total-dielectric-function Approach to Electron and Phonon Response in Solids
Topic: Condensed Matter Physics
Published: 1/1/1995
Authors: David R. Penn, S Lewis, Marvin Cohen
Abstract: The interaction between two test charges, the response of a solid to an external field, and the normal modes of the solid can be determined from a total dielectric function that includes both electronic and lattice polarizabilities as well as local- ...

92. Ultra-high resolution alpha particle spectroscopy using calorimetry
Topic: Condensed Matter Physics
Published: 9/23/2008
Authors: Robert Daniel Horansky, Joel Nathan Ullom, James A Beall, Gene C Hilton, Kent D Irwin, Don Dry, Beth Hastings, Stephen Lamont, Clifford R Rudy, Michael W Rabin
Abstract: Calorimetry has been used since the late 1700?s to measure the heat output of physical processes ranging from chemical reactions to the respiration of organisms . Calorimetry is performed by measuring the temperature change caused by heat release int ...

93. Ultrafast Demagnetization Dynamics at the M-edges of Magnetic Elements Observed Using a Tabletop High-Harmonic Soft X-Ray Source
Topic: Condensed Matter Physics
Published: 12/15/2009
Authors: Thomas J Silva, Justin M Shaw, Hans Toya Nembach, Chan La-O-Vorakiat, Henry C. Kapteyn, Margaret M. Murnane, Mark Siemens, Stefan Mathias, Roman Adam, Patrik Grychtol, Martin Aeschlimann, Claus M. Schneider
Abstract: We demonstrate that few-femtosecond soft x-ray pulses from high-order harmonic generation can probe femtosecond demagnetization dynamics. Using an experimental geometry where coherent high-harmonics are reflected from a magnetized Permalloy (Ni80Fe20 ...

94. Ultrafast Demagnetization Measurements using Extreme Ultraviolet Light: Comparison of Electronic and Magnetic Contributions
Topic: Condensed Matter Physics
Published: 1/23/2012
Authors: Thomas J Silva, Justin M Shaw, Hans Toya Nembach, Margaret M. Murnane, Henry C. Kapteyn, Chan La-O-Vorakiat, Stefan Mathias, Emrah Turgut, Teale A. Carson, Martin Aeschlimann, Claus M. Schneider
Abstract: Ultrashort pulses of extreme ultraviolet light from high-harmonic generation are a new tool for probing coupled charge, spin, and phonon dynamics with element specificity, attosecond pump-probe synchronization, and time resolution of a few-femtosecon ...

95. Ultrafast manetization enhancement in metallic multilayers driven by superdiffusive spin current
Topic: Condensed Matter Physics
Published: 9/4/2012
Authors: Thomas J Silva, Justin M Shaw, Hans Toya Nembach, Dennis Rudolf, Chan La-O-Vorakiat, Marco Battiato, Roman Adam, Emrah Turgut, Stefan Mathias, Margaret M. Murnane, Henry C. Kapteyn, Claus M. Schneider
Abstract: Uncovering the physical mechanisms that govern ultrafast charge and spin dynamics is crucial for understanding correlated matter as well as the fundamental limits of ultrafast spin-based electronics. Spin dynamics in magnetic materials can be driven ...

96. Valleytronics, Carrier Filtering and Thermoelectricity in Bismuth: Magnetic Field Polarization Effects
Topic: Condensed Matter Physics
Published: 9/25/2012
Authors: Adrian Popescu, Lilia Woods
Abstract: Valley polarization of multi-valleyed materials is of significant interest for potential applications in electronic devices. The main challenge is removing the valley degeneracy in some controllable way. The unique properties of bismuth in terms of i ...

97. Weak versus Strong Coupling Theory for Bi^d2^Sr^d2^CaCu^d2^O^d8^
Topic: Condensed Matter Physics
Published: 1/1/1990
Authors: Marvin Cohen, David R. Penn
Abstract: ^d^^d^^d^^d^ The latest optical determination of the superconducting-gap function for Bi^d2^Sr^d2^CaCu^d2^O^d8^ is consistent with weak-coupling theory. In contrast, a large discontinuity in heat-capacity data suggests strong-coupling superconductivi ...
