Abstract:
We consider the Goldstone Hermitian matrix model with a multitrace term. When
defining the solution on two intervals, we introduce a special parameter
ξξ describing the phase. We discuss the phase existence conditions at
ξ=0ξ=0 (or 11) and at ξ=1/2ξ=1/2. We calculate the propagator and
the vacuum energy in the symmetric case ξ=1/2ξ=1/2. In the general case, we
discuss the solution structure and calculate the magnetization and other
parameters expressed in terms of the sum of all the intervals.
