Condensed Matter seminar: "Low-Dimensional Properties of Atomically-Thin Materials and Systems"

Douglas Strachan, University of Kentucky

Atomically-thin materials represent the thinnest possible components of future device applications with extreme reduction in size scales. While tremendous progress has recently been made in understanding the large-…

Astro Seminar: CDM's Most Severe Small-scale Problem: The Ubiquity of Co-orbiting Satellite Galaxy Planes

Marcel Pawlowski (Case Western)

Comparisons of observed satellite galaxies with CDM
simulations have revealed numerous 'small-scale' problems. While the
missing-satellites, the core-cusp and potentially even the
too-big-to-fail…

Department Colloquium: Einstein and Quantum Mechanics: It’s Not What You Think

Douglas Stone, Yale

Einstein is well known for his rejection of quantum mechanics in the form it emerged from the work of Heisenberg, Born and Schrodinger in 1926.  Much less appreciated are the many seminal contributions he made to…

Condensed Matter Seminar: "Spin Fluctuations and Entanglement"

Ari Turner, Johns Hopkins University

I will compare the effects of quantum and thermal fluctuations in a
spin chain by calculating the probability distribution for spin
fluctuations in a segment.

The calculation will use the concept…

Department Colloquium: Restoration of Early Sound Recordings using Optical Metrology and Image Analysis

Carl Haber, LBL

Sound was first recorded and reproduced by Thomas Edison in 1877.  Until about 1950, when magnetic tape use became common, most recordings were made on mechanical media such as wax, foil, shellac, lacquer, and…

Condensed Matter Seminar: "Universally Slow"

Ariel Amir, Harvard University

Glassy systems are very common in nature, from disordered electronic and magnetic systems to window glasses and crumpled paper. Among their key properties are slow relaxations to equilibrium without a typical…
