A QCD Grid: 5 Easy Pieces?

A QCD Grid: 5 Easy Pieces?. Richard Kenway University of Edinburgh. the problem of quark confinement. quarks come in six flavours. quarks are confined by the strong force (QCD) into bound states called hadrons. we cannot directly measure the decay of one quark flavour into another

Variation of PL with temperature and doping

With increase in temperature: Lattice spacing increases so bandgap reduces, peak shift to higher wavelength Full width at half maximum increases due to increased lattice vibrations Peak intensity usually reduces As doping increases PL peak blueshifts due to band filling

Radioactive decay

Just for Kicks: a Molecular Dynamics Simulation by Dino B. Jet engine. Use the force from the Lennard-Jones potential. Begin from some initial positions. Particle positions adjust to minimize potential energy. ODE solved numerically with fourth order Runge-Kutta method. Radioactive decay.
