Observation of a 2D Bose-gas: from thermal to quasi-condensate to superfluid
We present experimental results on a Bose gas in a quasi-2D geometry near the Berezinskii, Kosterlitz and Thouless (BKT) transition temperature. By measuring the density profile, \textit{in situ} and after time of flight, and the coherence length, we ...

Mesoscopic Phase Coherence in a Quantum Spin Fluid
Mesoscopic quantum phase coherence is important because it improves the prospects for handling quantum degrees of freedom in technology. Here we show that the development of such coherence can be monitored using magnetic neutron scattering from a one ...

CLD-shaped Brushstrokes in Non-Photorealistic Rendering
Rendering techniques based on a random grid can be improved by adapting brushstrokes to the shape of different areas of the original picture. In this paper, the concept of Coherence Length Diagram is applied to determine the adaptive brushstrokes, in ...

Anomalous coherence length in superconductors with quantum metric
The coherence length ξ is the fundamental length scale of superconductors which governs the sizes of Cooper pairs, vortices, Andreev bound states, and more. In BCS theory, the coherence length is ξ BCS = ℏ v F /Δ, where v F is the Fermi velocity and Δ is

Spatial Coherence of a Polariton Condensate
We perform Young's double-slit experiment to study the spatial coherence properties of a two-dimensional dynamic condensate of semiconductor microcavity polaritons.

Coherent vs incoherent effects and Debye length
Abstract For some class of studies, the space charge is treated as frozen, allowing to capture the dynamics of incoherent phenomena. We explore the possibility that a beam may exhibit non-resonant coherent behavior by developing and studying a one-dimensional model.
