Topologically protected long-range coherent energy transfer

Long-range energy transfer in proteins.

Proteins are large and complex molecular machines. In order to perform their function, most of them need energy, e.g. either in the form of a photon, as in the case of the visual pigment rhodopsin, or through the breaking of a chemical bond, as in the presence of adenosine triphosphate (ATP). Such energy, in turn, has to be transmitted to specific locations, often several tens of A away from wh...

Topologically Protected State Transfer in a Chiral Spin Liquid

Topologically protected quantum state transfer in a chiral spin liquid.

Topology plays a central role in ensuring the robustness of a wide variety of physical phenomena. Notable examples range from the current-carrying edge states associated with the quantum Hall and the quantum spin Hall effects to topologically protected quantum memory and quantum logic operations. Here we propose and analyse a topologically protected channel for the transfer of quantum states be...

Topologically-Protected Low Dimensional Metals

Long-Range Plasmon-Assisted Energy Transfer between Fluorescent Emitters.

We demonstrate plasmon-assisted energy transfer between fluorophores located at distances up to 7  μm on the top of a thin silver film. Thanks to the strong confinement and large propagation length of surface plasmon polaritons, the range of the energy transfer is almost 2 orders of magnitude larger than the values reported in the literature so far. The parameters driving the energy transfer ra...
