, 2002 Noncommutative geometry governs the physics of quantum Hall (QH) effects. We introduce the Weyl ordering of the second quantized density operator to explore the dynamics of electrons in the lowest Landau level. We analyze QH systems made of $N$-component

Equations of motion, Noncommutativity and Quantization [PDF]
, 2006 We study the relation between a given set of equations of motion in configuration space and a Poisson bracket. A Poisson structure is consistent with the equations of motion if the symplectic form satisfy some consistency conditions.

Noncommutative point spaces of symbolic dynamical systems
Advances in MathematicsWe study point modules of monomial algebras associated with symbolic dynamical systems, parametrized by proalgebraic varieties which 'linearize' the underlying dynamical systems. Faithful point modules correspond to transitive sub-systems, equivalently, to monomial algebras associated with infinite words. In particular, we prove that the space of point

Can noncommutative effects account for the present speed up of the cosmic expansion?
, 2011 In this paper we investigate to which extent noncommutativity, a intrinsically quantum property, may influence the Friedmann-Robertson-Walker cosmological dynamics at late times/large scales.

Quantum Frustration as a Protection Mechanism in Non‐Topological Majorana Qubits
Annalen der Physik, Volume 538, Issue 4, April 2026.Quantum frustration is proposed as a robust protection mechanism for non‐topological ‐junction qubit. By leveraging distinct spatial profiles, co‐located Majorana modes couple to independent environments, creating incompatible pointer bases that suppress decoherence.

Noncommutative dynamical systems with two generators and their applications in analysis
Discrete and Continuous Dynamical Systems, 2003 The author studies the dynamics defined by two noncommuting interval maps \(\delta_1\) and \(\delta_2\). In general, each point has two possible images and the number of orbits of a given length grows exponentially with the length. The dynamics can be restricted by introducing two disjoint bounded guiding sets \(\mathcal{T}_1\) and \(\mathcal{T}_2 ...

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 4, April 2026.ABSTRACT The Lie group SE3$SE\left(3\right)$ of isometric orientation‐preserving transformation is used for modeling multibody systems, robots, and Cosserat continua. The use of these models in numerical simulation and optimization schemes necessitates the exponential map, its right‐trivialized differential (often referred to as the tangent operator ...

Exotic Galilean Symmetry and Non-Commutative Mechanics
Symmetry, Integrability and Geometry: Methods and Applications, 2010 Some aspects of the ''exotic'' particle, associated with the two-parameter central extension of the planar Galilei group are reviewed. A fundamental property is that it has non-commuting position coordinates.

physica status solidi (b), Volume 263, Issue 2, February 2026.We develop a basic‐principles model from an analytically tractable semi‐harmonic Hamiltonian and compare our predictions with experimental data for Cu, Al, Pb, Si, and Ge. The results are quite satisfactory, considering that there are no fitting parameters in our theory.
