SUMMARY:Optical and transport properties of metals with nontrivial ban
 d geometry\, R. G. Herb Condensed Matter Seminar\, Dima Pesin \, Unive
 rsity of Virginia
DESCRIPTION:I will describe how the geometry of the band structure of 
 metals manifests itself in their optical and transport properties. I p
 articular\, I will show that the natural optical activity of metals\, 
 equivalent to the so-called dynamic chiral magnetic effect\, stems fro
 m the intrinsic magnetic moments of quasiparticles\, and demonstrate t
 hat these magnetic moments can be of both intrinsic and extrinsic orig
 in. I will also discuss optical Hall response of chiral crystals in th
 e presence of a DC transport current – the gyrotropic Hall effect â€
 “ and show that it is related to the Berry curvature dipole. The latte
 r fact makes the gyrotropic Hall effect a diagnostic tool for topologi
 cal properties of three-dimensional chiral metals.
