Room-temperature soliton–polariton condensation in a hierarchical helical-nanowire fractal gel

Abstract

We report the emergence and persistence of a room-temperature soliton–polariton condensate (SPC) within an organic supramolecular gel, formed through centimeter-scale, hierarchically nested helical nanowire circuits self-assembled from single molecules. We uncover a fractal feedback route, where nested interference and spin–momentum locking across fractal layers confine photons by nearly two orders of magnitude, while vibrational energy trapping sustains the coherence of triplet-SPC qubits. Micro-PL and magneto-optics reveal integrated 4.6 ms SPC lifetimes (not single-polariton lifetime) in helical nanowires, matched by models capturing ballistic soliton jumps and quantized topological pumping. By nesting cavities fractally, this gel platform delivers on-demand, reconfigurable, room-temperature quantum light at centimeter scales—pointing to flexible, low-cost neuromorphic quantum hardware where problem-native polaritonic circuits emerge, self-stabilize, and compute in situ.
