weak coupling वाक्य

In quantum chromodynamics ( and also " N " = 1 perturbation theory in weak coupling ), then the fixed point is called a "'Banks Zaks fixed point " '.
For this special choice of chiral matter, the vacuum expectation values of the matter scalar fields can be chosen to completely break the gauge symmetry at weak coupling, allowing a reliable semi-classical saddle point calculation to proceed.
In the absence of an external magnetic field ( \ omega _ { c } = 0 ) the optical absorption spectrum ( 3 ) of the polaron at weak coupling is determined by the absorption of radiation energy, which is reemitted in the form of LO phonons.
Being an S-duality, Seiberg duality relates the strong coupling regime with the weak coupling regime, and interchanges chromoelectric fields ( gluons ) with chromomagnetic fields ( gluons of the dual gauge group ), and chromoelectric charges ( quarks ) with nonabelian't Hooft Polyakov monopoles.
Vibronic energy levels produced from Hush's model of adiabatic electron transfer for situations in which the ground state is localized and supports zero-point vibration ( weak coupling and intermediate coupling scenarios ), localized but does not support zero-point vibration, and delocalized ( strong coupling scenario ).
