Splitting of the spectrum of collective modes in helium-3 in the presence of order-parameter textures

Brusov and Popov have developed a method of studying the superfluidity of 3He by the use of functional integration. Using their method, the author has investigated the effect of textures on the spectrum of collective modes, taking the structure of the order parameter into account. Distortion of the energy gap will affect the spectrum of collective modes and in particular will be vitally important in its effect on one particular splitting
