Utilising the Heisenberg picture, a generalised interaction Hamiltonian is formulated and analysed across multiple specific scenarios. Our study focuses on the emergence of photon antibunching during short interactions. Notably, third-order photon antibunching at short timescales reveals a deeper degree of nonclassicality than that seen in first- and second-order cases. Enhanced nonclassical phenomena are observed under first-order coupling interactions due to the coherent entanglement of pump and harmonic fields. Furthermore, coherent or vacuum pumping leads to noticeable photon bunching in the harmonic mode. Sub-Poissonian characteristics intensify with increasing pump photon counts, emphasising that higher-order interactions significantly support the generation of nonclassical states. Minimising the second-order correlation function remains pivotal in quantum optics to realise photon antibunching.</p></div>","PeriodicalId":663,"journal":{"name":"Journal of Russian Laser Research","volume":"46 4-6","pages":"80 - 99"},"PeriodicalIF":0.8,"publicationDate":"2025-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147985237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we investigate the impact of deep gold doping on the structural evolution and electronic properties of amorphous silicon films (α-Si:Au) subjected to nanosecond-scale PLA. Gold is shown to play a dual physical role: first, it effectively suppresses crystallite coalescence, limiting crystallite size to 2.3–2.8 nm and preserving a heterophase structure with a high crystalline fraction (up to 78%), as quantitatively corroborated by Raman spectroscopy and the phonon confinement model; second, at concentrations of approximately ~ 5 · 10<sup>20</sup> cm<sup>-3</sup>, gold promotes the formation of a degenerate electron gas, manifesting as metallic-like behavior in the mid-infrared spectral range (2.5–5.0 µm). Key transport parameters—namely, carrier mobility <span>(leftlangle upmu rightrangle =76pm 8,mathrm{cm}^{2}/left(mathrm{V}cdot mathrm{s}right)leftlangle upmu rightrangle =76pm 8,mathrm{cm}^{2}/left(mathrm{V}cdot mathrm{s}right))</span> and resistivity ⟨ρ⟩ = (1.7 ± 0.2) · 10<sup>−4</sup> Ω · cm—were extracted from reflectance spectra using the Drude model. Despite the high density of defects and amorphous interlayers, the system achieves metallic conductivity owing to the elevated concentration of free carriers. These findings demonstrate the feasibility of synergistically tailoring both the nanostructure and electronic properties of silicon through the combined strategy of deep doping and ultrafast thermal processing, thereby opening new avenues for the development of functional silicon-based nanocomposites in optoelectronics and nanoelectronics.</p></div>","PeriodicalId":663,"journal":{"name":"Journal of Russian Laser Research","volume":"46 1-3","pages":"63 - 71"},"PeriodicalIF":0.8,"publicationDate":"2025-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147754418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
