| Abstract | Conventionally, atomic vapor is perceived as a non-living system governed by
the principles of thermodynamics and statistical physics. However, the
demarcation line between life and non-life appears to be less distinct than
previously thought. In a study of amplifying spin waves, we observe a
phenomenon reminiscent of life: The atomic spin wave stored in atomic vapor has
a capability of absorbing energy from an external light source, and exhibits
behaviors akin to active regeneration. We demonstrate that this regeneration
significantly enhances the lifetime and retrieval efficiency of the spin wave,
while concurrently the noise is effectively suppressed. Our results suggest
that the regeneration mechanism holds promise for mitigating the pronounced
decoherence typically encountered in spin waves carried by room-temperature
media, therefore offering potential applications in the realms of quantum
information and precision measurements at ambient conditions. |
