| Control of Magnetization in Topological Insulator/Magnetic Insulator Heterostructures |
Spintronics-based technology, which uses spins to represent and propagate information, holds promise to realize devices that surpass the current CMOS transistor technology in power, density and speed. For example, magnetic random-access memory (MRAM) based on… Show more Speaker: Prof. Peng Li, Auburn University |

| Journal Club |
This week the Condensed Matter Journal Club will feature rehearsals of student and faculty talks for the the March meeting of the APS.
Speaker: March Meeting Rehearsals |
|
| Hunting for topological phases amidst Hofstadter butterflies and disordered landscapes |
In this talk, I will discuss rich topological behavior in two related models – the Majorana wire and a Su-Schrieffer-Heeger ladder- in the presence of potential energy landscapes. An introduction of the two models and of techniques that directly provide information… Show more Speaker: Smitha Vishveshwara, UIUC |
|
| Climatic and Humanitarian Impacts of Nuclear War |
A nuclear war between any two nations, such as India and Pakistan, with each country using 50 Hiroshima-sized atom bombs as airbursts on urban areas, could inject 5 Tg of soot from the resulting fires into the stratosphere, so much smoke that the resulting climate… Show more Speaker: Dr. Alan Robock, Rutgers University |
|
| Fundamentals of Amorphous Oxide Semiconductors |
Amorphous oxide semiconductors (AOS)—ternary or quaternary oxides of post-transition metals—have attracted a lot of attention due to high carrier mobility which is an order of magnitude larger than that of amorphous silicon (a-Si:H). Unlike Si-based semiconductors,… Show more Speaker: Julia Medvedeva, University of Missouri S&T |
|
| Combined Magnetic Tweezers-TIRF microscopy for studying DNA-protein interactions |
Magnetic tweezers allow the user to apply force and torque to magnetic beads attached to single DNA molecules, and to observe the resulting changes in DNA extension. This technique, however, is limited to measuring a single degree of freedom: the distance between the… Show more Speaker: Maria Mills, MU Physics |
|
| Manifestations of band geometry in linear and nonlinear transport |
I will describe how the geometry of the band structure of metals manifests itself in their optical and transport properties. I particular, I will show that the natural optical activity of metals, equivalent to the so-called dynamic chiral magnetic effect, stems from… Show more Speaker: Dmytro Pesin, University of Virginia |
