- Abstract: We theoretically predict a kind of power-law-exponential (PLE) dipole-dipole interaction between quantum emitters in a 1D waveguide QED system. This unconventional long-range interaction is the combination of power-law growth and exponential decay couplings. Applying PLE interaction to a spin model, we uncover the rich many-body phases. Most remarkably, we find that PLE interaction can induce the ordered and critical spiral phases. These spiral phases emerge from the strong frustration generated by the power-law factor of PLE interaction, hence they are absent for other types of long-range interaction, e.g., pure exponential and power-law decay interactions. Our work is also applicable for the higher dimensional systems. It fundamentally broadens the realm of many-body physics and has the significant applications in quantum simulation of strong correlated matters.

Linear interactions that only create and annihilate single bosons can generate coherent states of light or motion.
Nth-order nonlinear interactions, that instead involve n bosons, lead to increasingly complex quantum behaviour.
Here, we demonstrate up to fourth-order bosonic interactions and demonstrate squeezing, trisqueezing, and quadsqueezing.
Our method presents no fundamental limit in the interaction order n and applies to any platform supporting spin-dependent linear interactions.

Due to quantum interference, we find that both the emitter-waveguide interaction and the amplitudes of bound states are periodically modulated by giant emitter's size.
