quantum turbulence

[′kwän·təm ′tər·byə·ləns]
(cryogenics)
A phenomenon observed in a channel filled with superfluid and subjected to a heat flux which exceeds a certain critical value, in which the superfluid becomes filled with a tangled mass of quantized vortex lines.

The graduate text explores perceptual control theory, extends the theoretical concept of 2D quantum turbulence to derive the analytical (closed-form) model of 3D turbulent wind flow, and presents recursive Bayesian techniques for cognitive estimation in autonomous systems and FastSLAM algorithms.
This is the strange world of quantum turbulence, which pops up not in coffee cups, but in super-cold helium, other types of strange cold matter and, some now think, the fabric of the universe.
Two colleagues, physicists who had been thinking about the dynamics of quantum turbulence since Feynman's time, got wind of the new technique.
By studying turbulence in other quantum fluids, such as an ultracold gaslike state of matter called a Bose-Einstein condensate, scientists might get a more complete picture of quantum turbulence and answer some lingering questions.
Kerson Huang, a physicist at MIT, thinks that quantum turbulence could explain a lot about the cosmos.
Another 17 articles review the current status of such condensed matters as quantum Hall effects: discovery and application, extreme mechanics: self-folding origami, glass and jamming transitions: from exact results to finite-dimensional descriptions, diagonalizing transfer matrices and matrix product operators: a medley of exact and computational methods, and Andreev reflections in superfluid 3He: a probe for quantum turbulence.
The author covers superfluidity and the order parameter, quantum turbulence, Higgs, renormalization, the Halper-Huang scalar field, the dynamics of spacetime, black holes, the big bang, the creation of matter, and a wide variety of other related subjects over the course of the bookAEs eleven chapters.
