I haven't seen any of the publications, but I note that in several cases in the above article they said they were able to "do" things, not simulate them. Presumably they were able to make a polariton and observe it. I expect the motion sensing aspect is still theory. It will be interesting to see if anything comes of it.
Is this an actual physical phenomena or is it just something that has appeared in a computer simulation? That is what it sounds like. It would be a game changer if it were able to be implemented in a simple and inexpensive manner, but that may not happen. Moving from a simulation to reality, (actual hardware), is often the show stopping task. In the interim these chaps have a nice grant to live on while chasing a theoretical "reality".
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
