Quantum Chromodynamics on the Lattice

Quantenchromodynamik

Die Quantenchromodynamik (kurz QCD) ist eine Quantenfeldtheorie zur Beschreibung der starken Wechselwirkung.

Elitzur's theorem

In quantum field theory and statistical field theory, Elitzur's theorem states that in gauge theories, the only operators that can have non-vanishing expectation values…

Nielsen–Ninomiya theorem

In lattice field theory, the Nielsen-Ninomiya theorem is a no-go theorem about placing chiral fermions on the lattice.

Polyakov loop

In quantum field theory, the Polyakov loop is the thermal version of Wilson loop, acting as an order parameter for confinement in pure gauge theories at nonzero…
