Abstract

The interaction between quantum two-level systems is typically short range in free space and in most photonic environments. We show that diminishing momentum isosurfaces with equal frequencies can create a significantly extended range of interaction between distant quantum systems. The extended range is robust and does not rely on a specific location or orientation of the transition dipoles. A general relation between the interaction range and properties of the isosurface is described for structured photonic media. It provides a new way to mediate long-range quantum behavior.

Long-range interactions in Weyl photonic crystals

Lei Ying, Ming Zhou, Michael Sabatini Mattei +4 more

The interaction between quantum two-level systems is typically short-range in free space and most photonic environments. Here we show that Weyl photonic crystals can create significantly extended long-range interaction between distant quantum systems because of their diminishing momentum isosurfaces with equal frequencies around isolated Weyl points. The extended range of interaction is robust and does not rely on specific location or orientation of the transition dipoles. A general relation between the interaction range and properties of the isosurface is described, which provides a recipe to identify other photonic environments for that enable long-range interaction. This work lays the foundation to use Weyl photonic crystals as a platform to mediate quantum behavior.

Tunable and Robust Long-range Coherent Dipole Interactions Mediated by Weyl Bound States

Iñaki García-Elcano, Alejandro González-Tudela, Jorge Bravo‐Abad

We investigate the quantum optical behavior of quantum emitters coupled to a Weyl-like photonic environment. For the single emitter case, we will report on the formation of a novel photon-atom bound state featuring a tunable power-law localization of the excitation around the emitter. When two emitters are considered we show that the emergent bound state can mediate tunable and robust long-range coherent interactions.

Realizing quantum optics in structured environments with giant atoms

Xin Wang, Huai-Bing Zhu, Tao Liu +1 more

To go beyond quantum optics in free-space setups, atom-light interfaces with structured photonic environments are often employed to realize unconventional quantum electrodynamics (QED) phenomena. However, when employed as quantum buses, those long-distance nanostructures are limited by fabrication disorders. In this work, we alternatively propose to realize structured light-matter interactions by engineering multiple coupling points of hybrid giant atom--conventional environments without any periodic structure. We present a general optimization method to obtain the real-space coupling sequence for multiple coupling points. We report a broadband chiral emission for frequency-tunable giant emitters, with no analog in other quantum setups. Moreover, we show that the QED phenomena in the band-gap environment, such as fractional atomic decay and dipole-dipole interactions mediated by a bound state, can be observed in our setup. Numerical results indicate that our proposal is robust against fabrication disorders of the coupling sequence. Our work opens up a route for realizing unconventional light-matter interactions.

Long-range mid-infrared energy transfer mediated by hyperbolic phonon polaritons

Gonzalo Álvarez-Pérez, Simone De Liberato, Huatian Hu

We provide a framework to theoretically describe long-range energy transfer in single and twisted two-dimensional hyperbolic slabs. We demonstrate that phonon polaritons (PhPs, quantum superpositions of photons and lattice vibrations in polar dielectrics) can mediate and enhance room-temperature energy transfer at ranges far exceeding those of conventional mid-infrared (MIR) platforms, and with extreme directionality. This is because the dipole-dipole interaction potential energy diverges along the asymptotes of the real-space hyperbolic opening angle. Our findings allow us to extend classical and quantum interactions between dipoles, typically strictly confined to the near-field, beyond several free-space MIR wavelengths. We use $α$-MoO$_3$ as a representative material, but this mechanism is not limited to the MIR: it is general to anisotropic media across the whole electromagnetic spectrum.

Mirror-mediated ultralong-range atomic dipole-dipole interactions

Nicholas Furtak-Wells, Dawson, Benjamin, Mann, Thomas +2 more

In three dimensions, dipole-dipole interactions which alter atomic level shifts and spontaneous decay rates only persist over distances comparable to the wavelength of the emitted light. In this paper we show that it is possible to significantly extend the range of these interactions with the help of a partially transparent asymmetric mirror interface. Suppose two two-level atoms are placed on opposite sides of the interface, each at the position of the mirror image of the other. In this case, their emitted light interferes almost exactly as it would when the atoms are right next to each other. Hence their dipole-dipole interaction assumes an additional maximum, even when the actual distance of the atoms is several orders of magnitude larger than the transition wavelength. Although the resulting ultralong-range interactions are in general relatively weak, we expect them to find applications in quantum technology, like non-invasive quantum sensing.
