A Model of Phase Transition with Breaking Supersymmetry
نویسندگان
چکیده
A phenomenological model of free energy is presented to demonstrate a phase transition from a state with supersymmetry to a state without supersymmetry. The model is equivalent, in a commensurate phase, to the extended sublattice model for antiferroelectricity and ferrielectricity. In a selected set of parameters, the state with supersymmetry (antiferroelectric state) transforms to the symmetry broken state (ferrielectric state), with decreasing temperature. The transition is either first or second order one depending on the coefficients of the free energy.

Spontaneous supersymmetry breaking in the 2D N=1 Wess-Zumino model.
We study the phase diagram of the two-dimensional N=1 Wess-Zumino model on the lattice using Wilson fermions and the fermion loop formulation. We give a complete nonperturbative determination of the ground state structure in the continuum and infinite volume limit. We also present a determination of the particle spectrum in the supersymmetric phase, in the supersymmetry broken phase and across ...
متن کاملPhase transition in a supersymmetric axion model
In a supersymmetric axion model where the scale for both supersymmetry breaking and Peccei-Quinn symmetry breaking is around 10 GeV, we find that there is a reasonable parameter space for a strongly first order phase transition at the scale.
متن کاملDynamical supersymmetry breaking and phase diagram of the lattice Wess-Zumino model
We study dynamical supersymmetry breaking and the transition point by non-perturbative lattice techniques in a class of two-dimensional N = 1 Wess-Zumino model. The method is based on the calculation of rigorous lower bounds on the ground state energy density in the infinite-lattice limit. Such bounds are useful in the discussion of supersymmetry phase transition. The transition point is determ...
متن کاملNon trivial spacetime effects in a supersymmetric model
We study a N = 1 supersymmetric model in a S1×R spacetime. We find that by choosing appropriate boundary conditions for the contributing fields supersymmetry can be preserved. However if we add a hard supersymmetry breaking term, we observe that for small values of the length of the S dimension, supersymmetry remains unbroken and breaks spontaneously when the length exceeds a critical value. Th...

The phase structure associated with the chiral symmetry is thoroughly investigated in de Sitter spacetime in the supersymmetric Nambu-Jona-Lasinio model with supersymmetry breaking terms. The argument is given in the three and four space-time dimensions in the leading order of the 1/N expansion and it is shown that the phase characteristics of the chiral symmetry is determined by the curvature ...
