Dear colleagues,

We are pleased to share with you and invite you to read our work on energy conserving space-time metamaterials/media which has been published in Applied Physics Letters (selected as Editor's pick). The link to the online version is pasted below:

Title: An energy conserving mechanism for temporal metasurfaces

The Computational Materials and Mechanics Group (CMMG) at the University of Connecticut has an opening for a postdoctoral researcher in the modeling of mechanical behavior polymer matrix composites across multiple scales starting immediately.

The postdoctoral researcher will use classical molecular dynamics simulations and machine learning algorithms to investigate the links between atomic-scale microstructure and the properties/behavior of polymer matrix composites under high-rate deformation.

Qualifications:

We have an open position as a PhD student in the area of fracture mechanics of fibre composites. The focus of the position is to develop element test specimens, i.e., test specimens that are purposely-designed with the aim of checking the accuracy of model predictions of damage evolution (two or more damage types) in composite structures subjected to static and cyclic loading

Applications are invited for two postdoctoral positions in the Geomechanics Group led by Dr. Buscarnera at Northwestern University. Both positions focus on the multi-scale behavior of granular solids, with one emphasizing numerical and theoretical modeling of the particle-continuum duality and the other emphasizing the experimental study of particulate materials through advanced characterization protocols. Competitive salary, exposure to a dynamic international academic environment and opportunities for professional development will be essential elements of the employment conditions.

Exceptional points (EP) are non-Hermitian degeneracies where eigenvalues and their corresponding eigenvectors coalesce. Recently, EPs have attracted attention as a means to enhance the responsivity of sensors, through the abrupt resonant detuning occurring in their proximity. In many cases, however, the EP implementation is accompanied by noise enhancement, leading to the degradation of the sensor’s performance.
