Key research themes

1. How is the internal wave-particle structure of photons theoretically characterized and experimentally supported?

This research area focuses on formulating a coherent physical and mathematical representation of photons that encapsulates their dual wave-particle nature as experimentally observed. It addresses the photon’s localization, energy quantization, polarization, and electromagnetic field representations. Insights in this theme are critical for reconciling classical electromagnetic theory with quantum phenomena and for foundational understanding crucial in quantum optics and photonics.

Key finding: Established the vector potential as a real photon wave function encoding simultaneous wave-particle properties, leading to a quantized electromagnetic field representation of single photons free from cavity constraints. The... Read more
Key finding: Demonstrated that photons behave as localized wave-corpuscles extended over one wavelength and guided by a non-local real vector potential wave function oscillating with circular polarization. The quantization framework... Read more
Key finding: Constructed a Lorentz-covariant quantum field theoretical framework describing photons as localized bosonic excitations ('blips') circumventing traditional no-go theorems by relaxing spherical symmetry assumptions to... Read more
Key finding: Provided an integrative overview of photon physical characteristics emphasizing the indivisibility of single photons, their ability to exhibit superposition through spatially split wavefunctions at beamsplitters, and the... Read more

2. What is the theoretical and experimental status of the photon structure function in quantum chromodynamics (QCD) and its implications for defining photon parton distributions?

This theme explores the perturbative and non-perturbative aspects of the photon’s hadronic structure as described by photon structure functions, focusing on their Q^2 evolution, parton content, and the derivation and precision of QCD corrections. It addresses the photon’s dual role as both a pointlike particle and a complex hadronic object fluctuating into quark-antiquark pairs, impacting parton density functions (PDFs) and deep inelastic scattering phenomenology.

Key finding: Reviewed the theoretical foundation and historical evolution of the photon structure function F_2^γ(x,Q^2), emphasizing the QCD-predicted logarithmic growth with ln Q^2 and distinct increase in x away from endpoints. It... Read more
Key finding: Charted the progress from early parton model calculations to the next-to-leading order (NLO) and next-to-next-to-leading order (NNLO) QCD analyses of F_2^γ, including Witten’s foundational work and subsequent refinements.... Read more
Key finding: Analyzed the impact of higher-order singularities and non-perturbative hadronic contributions on theoretical predictions of the photon structure function. Demonstrated that these uncertainties are negligible for momentum... Read more
Key finding: Presented high-precision measurements of dijet cross sections sensitive to the photon’s parton densities, especially at high x_γ. The data were compatible with next-to-leading order QCD predictions using recent photon PDFs,... Read more

3. How do concepts beyond standard photon quantum theory, such as dark photons and photon vortices, extend our understanding of photon structure in new physics and spatial configuration contexts?

This theme investigates innovative extensions of photon theory beyond the standard quantum electrodynamics framework, including hypothesized dark photon gauge bosons mediating hidden sector interactions, and structurally complex photon states characterized by three-dimensional vortex-like angular momentum. These studies impact searches for new physics, dark matter interactions, and the emergent 3D spatial topology of quantum fields.

Key finding: Thoroughly reviewed the theoretical basis and experimental constraints on the dark photon, a hypothetical U(1) gauge boson kinetically mixed with the visible photon. It elucidated differences between massless and massive dark... Read more
Key finding: Developed and experimentally verified a novel theory for photons acquiring three mutually perpendicular angular momenta by interaction with intricately structured helical nanowire templates, creating stable three-dimensional... Read more
