Study unveils new half-light half-matter quantum particles

Prospects of developing computing and communication technologies based on quantum properties of light and matter may have taken a major step forward thanks to research by City College of New York physicists led by Dr. Vinod Menon.

In a pioneering study, Professor Menon and his team were able to discover half-, half-matter particles in atomically thin semiconductors (thickness ~ a millionth of a single sheet of paper) consisting of two-dimensional (2D) layer of molybdenum and sulfur atoms arranged similar to graphene. They sandwiched this 2D material in a light trapping structure to realize these composite quantum particles.

"Besides being a fundamental breakthrough, this opens up the possibility of making devices which take the benefits of both light and matter," said Professor Menon.

For example one can start envisioning logic gates and signal processors that take on best of light and matter. The discovery is also expected to contribute to developing practical platforms for .

Dr. Dirk Englund, a professor at MIT whose research focuses on quantum technologies based on semiconductor and optical systems, hailed the City College study.

"What is so remarkable and exciting in the work by Vinod and his team is how readily this strong coupling regime could actually be achieved. They have shown convincingly that by coupling a rather standard dielectric cavity to exciton-polaritons in a monolayer of molybdenum disulphide, they could actually reach this strong coupling regime with a very large binding strength," he said.

Professor Menon's research team included City College PhD students, Xiaoze Liu, Tal Galfsky and Zheng Sun, and scientists from Yale University, National Tsing Hua University (Taiwan) and Ecole Polytechnic -Montreal (Canada).

The study appears in the January issue of the journal Nature Photonics.

Photons probably are the mechanical catalyst to produce dark matter in deep space where dark energy regions exist, if its a found mechanical principle on earth it has an application in creation and construction

Fantastic, isn't this an atomic modal property of bound matter?

Aaaaaaand use entangled light hour photons strongly interacting with matter and I bet you could get the matter to teleport like an Esaki diode! Bound matter? Isn't that the 1s2 2s2 2p6 etc orbitals as a 2D surface? Dark matter seems to keep its distance like hot hydrogen in space. I don't think it ever had neutrino cooling like baryonic matter in the early universe.The apparatus might make a detector for normally invisible states of interaction like dark matter and energy. You can use something other than a photon. Or it would make great science fiction. Can you see focusing beams of wave like tritium in a fusion reactor? It seems like their cavity only reacts with matter in a specific orientation.

This sounds like a hybrid of photon structure and Cooper pairs.

Do any of these guys know what they are talking about?
