Absence of long-range coherence in the parametric emission of photonic wires
Open accessAbstract
We analytically investigate the spatial coherence properties of the signal emission from one-dimensional optical parametric oscillators. Because of the reduced dimensionality, quantum fluctuations are able to destroy the long-range phase coherence even far above threshold. The spatial decay of coherence is exponential and, for realistic parameters of semiconductor photonic wires in the strong exciton-photon coupling regime, it is predicted to occur on an experimentally accessible length scale.

As a rough estimate, the fluctuations in this one-dimensional quasi-condensate can be interpreted as a temperature on the order of the loss rate, k_B T ∼ ħγ.
“As a rough estimate, the fluctuations in this one-dimensional quasi-condensate can be interpreted as a temperature on the order of the loss rate k B T ∼ ħγ [127].”
From How to exploit driving and dissipation to stabilize and manipulate quantum many-body states (2025) · cites this paper as [127]
Section VI (p. 5) says that damping-associated noise plays the role of temperature in the non-equilibrium system, and Section VI (p. 4) describes the relevant noise term as being of the order of the damping rates. Our copy does not state the specific estimate k_B T ∼ ħγ, so it supports the qualitative analogy but not that quantitative relation. (LLM, conf=0.79)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
