Interactive visualizations
Real-time visualizations of quantum chromodynamics, parton evolution, mechanical distributions and relativistic kinematics. Each one opens full-screen and runs in the browser.
αs(Q²) — Running coupling
The running of the strong coupling: asymptotic freedom at high Q², confinement at low Q², with an adjustable energy scale.
DGLAP parton evolution
Gluon and sea-quark distributions grow and take over from the valence quarks as Q² increases through the splitting kernels.
Pion mechanical distribution
Pressure, shear and energy distributions inside the pion from the light-front quark model.
QCD quantum field
Lattice QCD, flux tubes, bubble-chamber tracks and Feynman diagrams — four modes to switch between.
Generalized distribution amplitude
The γγ* → π⁰π⁰ process animated: photon collisions and pion-pair production.
Instant form vs front form
Equal-time (instant form) and light-front (front form) relativistic dynamics side by side.
Proton live wallpaper
A layered parallax proton with particle overlays and a slow Ken Burns zoom.
