Topological Quantum Numbers in Quasicrystals

Israel Journal of Chemistry
AbstractWe provide an overview on the theory of topological quantum numbers from the point of view of non‐commutative topology. Topological phases are described by K‐groups of C*‐algebras. The algebras are constructed from the set of positions of the nuclei of the materials we want to study.

Introduction to Topological Quantum Numbers

2007
These lecture notes were prepared rather soon after I completed my book on Topological quantum numbers in nonrelativistic physics, which was published by World Scientific Publishing Co. Pte. Ltd., Singapore, in early 1998. I have not attempted to make a completely fresh presentation, but have cannibalized the text of my book to produce something ...

Quantum Correlations and Topological Quantum Numbers in the Fractional Quantum Hall Effect

Berichte der Bunsengesellschaft für physikalische Chemie, 1993
AbstractIt is demonstrated that the fractional Hall plateaux, experimentally observed in some nearly ideal samples at very low temperatures, are manifestations of strongly correlated objects explicitly connected with Coleman's extreme case and Yang's concept of off‐diagonal long‐range order (ODLRO). This interpretation yields (n – 1)/(2n – 1), n = 2,3,…

Topological Quantum Numbers in Nonrelativistic Physics

1998
Voltage measurements using the ac Josephson effect and electrical resistance measurements using the quantum Hall effect are capable of very high precision, despite the relatively poor control of details of the devices. Such measurements rely on topological quantum numbers, which, unlike symmetry-based quantum numbers, are insensitive to deviations of ...

Shift and Spin Vector: New Topological Quantum Numbers for the Hall Fluids

Physical Review Letters, 1992
We discuss some new quantum numbers (spin vector) for the Hall fluid, representing orbital spin degrees of freedom. We show that the spin vectors are quantized. In the absence of impurites, two Hall fluids with different spin vectors cannot change into each other without a phase transition and closing of the energy gap. In principle the spin vector can

Topological Quantum Numbers of m-Particle Systems

1998
The category of topological spaces and continuous maps is an important conception in theoretical physics. Topological spaces appear in many situations, e. g. as a configuration space or as a state space of a classical or quantum mechanical system, and the elements of these spaces carry information about observable properties of the system.

How Topological Concepts Lead to Quantum Numbers for Baryons

1985
Strong interaction physics is currently believed to be determined by quantum chromodynamics. If this is correct, then it follows that all of nuclear physics must, somehow, be a consequence. Unravelling these consequences will be a daunting task, for nuclear physics is the regime of longdistances (on the scale of ΛQCD) and it is precisely here that the ...

Topological Origins of Number Theory in Quantum Systems

This establishes a theoretical framework wherein number-theoretic structures, particularly prime factorization, emerge as causal signatures of topological organization in quantum critical systems. We posit a foundational ontological inversion: physical reality, including particles and spacetime, is not fundamental but emerges from a deterministic ...
