Description
Summary:We introduce a novel class of coherent states, termed <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><msub><mi mathvariant="script">W</mi><mrow><mi>α</mi><mo>,</mo><mi>β</mi><mo>,</mo><mi>ν</mi></mrow></msub></semantics></math></inline-formula>-coherent states, constructed using a deformed boson algebra based on the generalised factorial <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><msub><mrow><mo>[</mo><mi>n</mi><mo>]</mo></mrow><mrow><mi>α</mi><mo>,</mo><mi>β</mi><mo>,</mo><mi>ν</mi></mrow></msub><mo>!</mo></mrow></semantics></math></inline-formula>. This algebra extends conventional factorials, incorporating advanced special functions such as the Mittag-Leffler and Wright functions, enabling the exploration of a broader class of quantum states. The mathematical properties of these states, including their continuity, completeness, and quantum fluctuations, are analysed. A key aspect of this work is the resolution of the Stieltjes moment problem associated with these states, achieved through the inverse Mellin transformation method. The framework provides insights into the interplay between the classical and quantum regimes, with potential applications in quantum optics and fractional quantum mechanics. By extending the theoretical landscape of coherent states, this study opens avenues for further exploration in mathematical physics and quantum technologies.
