Oddities of Quantum Colorings

Laura Mančinska, David E. Roberson
2016 Baltic Journal of Modern Computing  
Oddities Here we point out some interesting properties of the graph G 13 related to quantum colorings. Apex vertex. Quantum chromatic number χ q often behaves similar to the chromatic number χ.  ...  The curious case of the thirteen vertex graph In this section we define a graph on thirteen vertices, denoted G 13 , which will let us exhibit the promised oddities of quantum colorings.  ...

Oddities of quantum colorings [article]

Laura Mančinska, David E. Roberson
2018 arXiv   pre-print
We study quantum analogs of graph colorings and chromatic number.  ...  Almost all of the known constructions of quantum d-colorings start from d-dimensional orthogonal representations.  ...  The curious case of the thirteen vertex graph In this section we define a graph on thirteen vertices, denoted G 13 , which will let us exhibit the promised oddities of quantum colorings.  ...

Cognitive science and the connection between physics and mathematics [article]

Anshu Gupta Mujumdar, Tejinder P. Singh
2015 arXiv   pre-print
We use the example of quantum theory to demonstrate the all too human nature of the physics-mathematics connection: it is at times frail, and imperfect.  ...  Our resistance to take this imperfection sufficiently seriously [since no known experiment violates quantum theory] shows the fundamental importance of experiments in physics.  ...  There are four oddities in this connection, bordering on the illogical, which suggest that quantum theory might be incomplete.  ...

Green InGaN/GaN LEDs: High luminance and blue shift [article]

Anis Daami, François Olivier, Ludovic Dupré, Christophe Licitra, Franck Henry, François Templier, Stéphanie Le Calvez
2019 arXiv   pre-print
Light-emission homogeneity investigation, carried out by photoluminescence mapping, shows that the Quantum Confinement Starck Effect (QCSE) is less significant at the edges of μLEDs.  ...  Electroluminescence shows a subsequent color green-to-blue deviation at high carrier injection levels.  ...  Nevertheless, this voltage increase induces the appearance of another oddity. Actually, the emitted-light wavelength shifts towards lower values.  ...

Physics, Curiosities, Oddities, and Novelties John Kimball

2016 MRS bulletin  
In a book of 152 pages, there are 48 color photos (most of them full page), 12 pages of technical data, and 11 workshops to facilitate material exploration.  ...  In this context, the description of particle physics using Feynman diagrams and quantum electrodynamics is-taking the impossibility of this task into account-exemplary.  ...

Solitary excitations in one-dimensional spin chains

Anton Wöllert, Andreas Honecker
2012 Physical Review B  
The underlying question of this work is the correspondence between classical solitons and solitons in quantum mechanics.  ...  For the case of the XXZ model it is shown that the real-time evolution of quantum wave packets accompanied by spreading is in qualitative accordance with the one predicted by classical solitons.  ...  Parts of the DMRG code were based on prior work by R. Peters. A.H. acknowledges support by the Deutsche Forschungsgemeinschaft via a Heisenberg fellowship (Project HO 2325/4-2).  ...

An Ishihara-style test of animal colour vision [article]

Karen L Cheney, Naomi Green, Alexander Vibert, Misha Vorobyev, Justin N. Marshall, Daniel C Osorio, John A Endler
2018 bioRxiv   pre-print
We measured discrimination thresholds by testing the detection of target colours that were of increasing colour distances (ΔS) from distractor dots in different directions of colour space.  ...  We demonstrate the success of this method with triggerfish, Rhinecanthus aculeatus, and highlight behavioural parameters that can be measured, including success of finding the target dot, time to detect  ...  with a range of probable luminance channels (i.e. combined quantum catch 334 of double cone vs quantum catch of long wavelength receptor alone). 335 Using this methodology, our study demonstrated that  ...

It from Bit from It from Bit ... Nature and Nonlinear Logic [chapter]

Wm. C. McHarris
2015 The Frontiers Collection  
However, just as with the oddities of relativity, upon more detailed examination these nonlinear peculiarities are discovered to be considerably more logical than the paradoxes of orthodox quantum mechanics  ...  Then along came quantum information science with the enticement of super-fast quantum computing.  ...  It can be seen that between every two colors lies a a basin of the third color, ad infinitum.  ...

Quantum computing. I

A. Glassner
2001 IEEE Computer Graphics and Applications  
The world of quantum physics is strange and beautiful. It's full of all sorts of interesting philosophical questions, including the nature of reality and consciousness.  ...  In this column, we'll get started with a look at the general principles of quantum mechanics as they apply to quantum computing.  ...  This is just the tip of the weird iceberg that quantum mechanics describes. Amidst all these oddities, we must remember two important truths. First, as weird as it is, quantum physics works.  ...

Foundations and applications of weak quantum measurements

Yakir Aharonov, Eliahu Cohen, Avshalom C. Elitzur
2014 Physical Review A. Atomic, Molecular, and Optical Physics  
This article, the first in two parts, explores novel applications of weak measurement. We first revisit the basic principles of quantum measurement with the aid of the Michelson interferometer.  ...  Finally a practical application of this experiment is demonstrated, where a single photon measures the various transmission coefficients of a multiport beam-splitter yet remains superposed.  ...  We also thank several anonymous referees who helped us in clarifying several points and improve the structure of the paper.  ...
