Physicists in Germany and Hungary claim that ultracold atoms in an optical lattice could be used to simulate certain aspects of quantum chromodynamics (QCD) -- the theory that describes how quarks are ...

An atom could be made to emit an optical signal that is usually associated with another type of atom, according to calculations done by Andre Campos, Denys Bondar, Herschel Rabitz and Renan Cabrera at ...

The QCD vacuum (i.e., the ground state of vacuum in the quantum chromodynamics regime) is theoretically characterized by the presence of non-zero expectation values of condensates, such as gluons and ...

During the evolution of the Universe there were particle-physics-related transitions. Although there are strong indications of an inflationary period, we know little about how it affected possible ...
