We impose uniform electric fields both parallel and normal to 180^o ferroelectric domain walls in PbTiO3 and obtain the equilibrium structures using the method of anharmonic lattice statics. In addition to Ti-centered and Pb-centered perfect domain walls, we also consider Ti-centered domain walls with oxygen vacancies. We observe that electric field can increase the thickness of the domain wall considerably. We also observe that increasing the magnitude of electric field we reach a critical electric field E^c; for E > E^c there is no local equilibrium configuration.

Our group has two research openings for people with expertise on mechanism design / dynamic and vibration analysis of actuators cater to 10 Tbits/square inch hard disk drives.

------Graduate Students Openings------

Dear colleagues,

I would like to draw your attention to the minisymposium:

Computational Methods for Multiscale and Multiphysics Wave Phenomena

at the upcoming 11th U.S. National Congress on Computational Mechanics (USNCCM-11, http://www.usnccm.org/) to be held on July 25-29, 2011 in Minneapolis, MN.

We have several open postdoc positions, to be filled immediately.



The first project is focused on thermal management. The project involves the computational and theoretical analysis of graphene/graphite-metal nanocomposites and experimental work carried out by other team members. We are looking for a strong person with background in thermal and mechanical properties of materials, preferrably with background in molecular simulation.

We are delighted to invite you to submit your contribution to ISDMM11. The conference will take place in Seville, Spain, June 27 – July 1st 2011.

The Irish Research Council (http://www.ircset.ie/tabid/64/default.aspx) has a funding scheme for postdoctoral researchers. I am seeking someone to submit an application to IRCSET to obtain funding to work within my group, in Modelling of CNT-based nanocomposites. The chances of success are high for candidates with a good research record. The deadline for applications is December 8th.
