    Generalized parton distributions from lattice QCD

    Krzysztof Cichy🇵🇱 · Martha Constantinou🇺🇸

    This chapter gives an overview of the recent progress in extracting generalized parton distributions from lattice QCD. We briefly recall the theoretical principles of GPDs and explain the two most common lattice approaches, Ji's quasi-distributions and Radyushkin's pseudo-distributions. In the second part of the chapter, we review the lattice results obtained from these two frameworks. Finally, we offer a discussion of future prospects of lattice extractions of GPDs.

    Quantum Resources in Disorder-Free Localization Dynamics of Gauge Theories

    Devendra Singh Bhakuni🇮🇹 · Giovanni Cataldi🇩🇪 · Jad C. Halimeh🇩🇪 · Emanuele Tirrito🇨🇭

    Quantum-state complexity diagnostics provide valuable insight into many-body dynamics, information scrambling, and quantum computation. Here, we investigate the real-time dynamics of quantum complexity in -dimensional Abelian U(1) and non-Abelian SU(2) lattice gauge theories (LGTs), focusing on the disorder-free localization (DFL) regime. Using stabilizer Rényi entropy, participation Rényi entropy, and fermionic non-Gaussianity as measures of complexity, we observe, for both theories, two main behaviors as a function of the gauge coupling: at intermediate values, a power-law relaxation towards saturation, consistent with observations in many-body localization, and, at sufficiently large values, an ultraslow double-logarithmic growth, which we substantiate with a configuration-space bound verified by exact counting. Our results not only provide deeper insight into the dynamics of DFL but also highlight the role of gauge invariance in constraining quantum resources and are relevant to recent quantum simulations of LGTs.
