A team of researchers from the Institute for Quantum Electronics, ETH Zürich, the Max Planck Institute of Quantum Optics and the Munich Center for Quantum Science and Technology has found a way to boost polaritonic nonlinearity. In their paper published in the journal Physical Review X, the group describes building a mechanism to create polaron-polaritons, which led to a boost in polaritonic nonlinearity.
