Fractals, coherent states and self-similarity induced noncommutative geometry

Abstract: The self-similarity properties of fractals are studied in the framework of the theory of entire analytical functions and the $q$-deformed algebra of coherent states. Self-similar structures are related to dissipation and to noncommutative geometry in the plane. The examples of the Koch curve and logarithmic spiral are considered in detail. It is suggested that the dynamical formation of fractals originates from the coherent boson condensation induced by the generators of the squeezed coherent states, whose (fractal) geometrical properties thus become manifest. The macroscopic nature of fractals appears to emerge from microscopic coherent local deformation processes.

Fractals, Coherent States, and Self-Similarity Induced Noncommutative Geometry

The paper explores the intriguing interplay between fractals, coherent states, and noncommutative geometry, unveiling a novel framework for understanding self-similar structures from a quantum dynamics perspective. This multidimensional exploration links the macroscopic manifestation of fractal patterns to quantum interference and coherent boson condensation, forming a coherent theoretical foundation supported by quantum field theory (QFT).

Key Insights and Techniques

The study focuses on deterministic fractals, such as the Koch curve and logarithmic spiral, explaining their self-similarity properties through the theory of entire analytical functions and $q$-deformed algebra of coherent states. Importantly, the paper proposes that fractals arise from coherent boson condensation processes, with coherent squeezed states playing a pivotal role.

Self-Similarity and Coherent States

The self-similarity of fractals is linked to squeezed coherent states, showing that fractal structures can be realized in terms of $q$-deformed coherent states. The Koch curve serves as a primary example, where the $q$-deformation parameter facilitates a "magnifying lens" effect, unfolding the fractal's self-similar stages.

Logarithmic Spiral

Similarly, the logarithmic spiral's self-similarity is captured by coherent state dynamics, supporting a recursive process where rescaling affects radius ratios. The golden spiral variant is related to the Fibonacci progression, highlighting a connection between natural phenomena and mathematical sequences observed across various scientific domains.

Quantum Dynamics and Dissipation

A distinguishing feature of the paper is its quantum dynamics perspective on fractals, asserting that these structures are instances of macroscopic quantum systems. Quantum dissipation and $q$-deformation are foundational, leading to a generalized coherent state description that mirrors fractal self-similarity.

Noncommutative Geometry

The study positions fractal self-similarity within noncommutative geometry, correlating quantum interference phases with noncommutative planes. A novel insight is the connection between the $q$-deformation parameter and noncommutative length scales, suggesting a quantum geometric underpinning to fractal phenomena.

Implications and Future Directions

The paper suggests that understanding fractals as macroscopic quantum systems opens valuable avenues for theoretical and practical exploration. By associating fractal properties with coherent state transformations, the study presents potential applications across condensed matter physics, quantum optics, and computational fields.

The theoretical framework set forth may prompt further interdisciplinary research into fractal morphogenesis and its implications in neuroscience, biology, and even artificial intelligence. The speculative yet grounded approach hints at broader possibilities concerning unitary inequivalent representations and the evolution of fractal dynamics under quantum dissipation principles.

In conclusion, this exploration of fractals through the lens of quantum dynamics and noncommutative geometry paves the way for deeper analysis and applications across scientific domains, emphasizing the need for continued investigation into the role of coherent states and quantum phenomena in the formation and evolution of complex structures.
