Multilayer reflective boundaries used to guide and resonate light impart reflective phase shifts that depend on both angle of incidence and polarization. In cavities, these phase shifts can have a large effect on the spatial and polarization patterns of the eigenmodes, creating completely new structures. Here I discuss two new families of modes found in simple dome-shaped cavities. Both families owe their existence to derivatives of the boundary phase shift with respect to incident angle.

Tremendous progress has been made recently in the development of
magnetic Heusler compounds specifically designed as materials for
spintronic applications [1]. While problems in the field of
spintronics remain, the use of half-metallic Heusler compounds
provides a prospect for novel solutions.
Heusler compounds can be made with high spin polarization and high
Curie temperature as well as high spin injection efficiency, either
very low or high damping, tunable magnetic moment (low and high
magnetic moments can be realized), and tunable anisotropy. There is,

This seminar is offered for 1 credit as Introduction to Research, PH607, Section 4, CRN 24127. It is scheduled in Winter term only! New graduate students and graduate students who have not joined a research group should register for credit. Drop-ins by other interested parties are welcome.

The rapid melting of the Pine Island Glacier (PIG) has been attributed to ocean melting. Specifically, this ocean melting is attributed to currents and tides pumping Circumpolar Deep Water (CDW) into the ice shelf cavity. To illuminate the role of tides in the melting of the PIG and the circulation and mixing at the ice shelf front, a time series of yo-yo CTD (Conductivity, Temperature, and Depth) data collected in the PIG outflow region was analyzed. The water column in the region consisted of two primary layers, a meltwater layer exiting the ice shelf cavity over a layer of CDW.

Everyone is welcome to attend the first annual physics department open house.

The first hour from 4-5pm will be a colloquium in wngr 153 led by a group of faculty members, addressing: What a physics major entails, What kind of jobs a physics degree prepares you for, Undergraduate research opportunities available within the physics department, Current ‘hot topics’ in physics being researched by OSU physics faculty and students.

Bill Cowell is a PhD candidate in John Wager's group in Electrical Engineering. His talk will focus on tunneling devices built at OSU that use amorphous metal technology to achieve ultra-thin tunnel barriers.

In spin transfer devices a dc electric current is capable of exciting stable precession states of the magnetic moment. These auto-oscillations are powered by the current source and were found to have many remarkable properties, e.g., very narrow line widths. Precession regimes are thought to be useful for engineering nano-generators of microwave power on a chip.

Thermal chemical vapor deposition was used to grow graphene on copper substrates [1] and isotopic labeling (13C vs 12C [2]) was used to study how graphene grows on Cu [3]. Graphene holds potential as a transparent electrically conductive thin film [4a, b, c] and for electrical energy storage (e.g.,,graphene-based ultracapacitors [5]). Our top-down approaches [6,7] were the first to target obtaining individual layers of graphite obtained by micromechanical exfoliation.
