Instantons and spontaneous color symmetry breaking
The instanton interaction in QCD generates an effective potential for scalar quark-antiquark condensates in the color singlet and octet channels. For three light quark flavors the cubic term in this potential induces an octet condensate and “spontaneous breaking” of color in the vacuum. Realistic masses of the ρand η-mesons are compatible with renormalization-group-improved instanton perturbati...

متن کاملChiral Symmetry Breaking by Instantons
Instantons are certain configurations of the Yang–Mills potentials Aμ(x) satisfying the equations of motion D μ F b μν = 0 in euclidean space, i.e. in imaginary time. The solution has been found by Belavin, Polyakov, Schwartz and Tiupkin in 1975 [1]; the name ”instanton” has been suggested by ’t Hooft in 1976 [2], who also made a major contribution to the investigation of the instantons propert...
متن کاملGlassy slowdown and replica-symmetry-breaking instantons.
Glass-forming liquids exhibit a dramatic dynamical slowdown as the temperature is lowered. This can be attributed to relaxation proceeding via large structural rearrangements whose characteristic size increases as the system cools. These cooperative rearrangements are well modeled by instantons in a replica effective field theory, with the size of the dominant instanton encoding the liquid's ca...
متن کاملNonperturbative Spontaneous Symmetry Breaking
One of the most astonishing results of quantum field theory is spontaneous symmetry breaking. One can say that it is the situation when something arises from the quantization. This means that on the quantum level one has something that was not present on the classical level. Coleman and Weinberg [1] write : “ . . . higher-order effects may qualitatively change the character of a physical theory...
