Abstract:  The field of nanomagnetism has recently attracted tremendous attention as it can potentially deliver low-power, high-speed and dense non-volatile memories. It is now possible to engineer the size, shape, spacing, orientation and composition of sub-100 nm magnetic structures. This has spurred the exploration of nanomagnets for unconventional computing paradigms. Here, we harness the energy-minimization nature of nanomagnetic systems to solve the quadratic optimization problems that arise in computer vision applications, which are computationally expensive. By exploiting the magnetization states of nanomagnetic disks as state representations of a vortex and single domain, we develop a magnetic Hamiltonian and implement it in a magnetic system that can identify the salient features of a given image with more than 85% true positive rate. These results show the potential of this alternative computing method to develop a magnetic coprocessor that might solve complex problems in fewer clock cycles than traditional processors.

Interview with Dr. Sanjukta Bhanja 

Team "Secret" comprising of Jayita Das and Kevin Scott is the first-place winner of NYU organized Cybersecurity event "The Embedded Security Challenge"

The Embedded Security Challenge deals with the security and trustworthiness of hardware. This year, students were challenged to focus on emerging technologies and materials and to prove to us why they are valuable and secure. Representatives of 10 student teams were invited to the finals, where they presented their research to judges. All three winners were from Florida:
