Job description

Daedalus, our research group at the Georgia Institute of Technology, is announcing an opening for a postdoctoral researcher. We are looking for an individual with a background in solid/experimental mechanics or polymer engineering to contribute to our pioneering projects on high-throughput mechanical testing methods and mechanics of flexible materials. This project is a collaborative effort with a major industrial partner in the US, making it an excellent opportunity for those interested in exploring a novel application area and pursuing an academic career.

Challenges

For ionic and dielectric materials, the polarization (dipole moment per unit cell) is plagued with non-uniqueness. As a 1D example, consider a 1D line of alternating positive and negative charges. If we agree that the dipole is a vector from the negative to the positive charge, then we have two choices for the dipole. This is because every negative charge has two different positive charges in its immediate vicinity. The situation gets more complicated in higher dimensions.
