Model Hamiltonian

We numerically diagonalize the Dimer-Trimer (DT) model Hamiltonian around the SU(3) symmetric point. As a result, we discover the phase transition at this point which belongs to the Berezinskii-Kosterlitz-Thouless (BKT)-like universality class.

Tremendous Impact

If baryon number nonconservation exists in the form of an effective six-quark operator which also changes strangeness by four units, it could have a tremendous impact on the absolute stability of strange quark matter. We show that such an operator is negligible in the supersymmetric standard model with [Formula: see text] terms in the superpotential, but may be of importance in models with exotic particle content. From the experimental lower limit of 1025 years on the stability of nuclei, we find a model-independent lower limit of the order 105 years on the stability of strange matter against such decays.

Fermion Action

We investigate the critical end line of the finite temperature phase transition of QCD away from the SU(3)-flavor symmetric point at zero chemical potential. We employ the renormalization-group improved Iwasaki gauge action and non-perturbatively O(a)- improved Wilson-clover fermion action. The critical end line is determined by using the intersection point of kurtosis, employing the multi-parameter, multi-ensemble reweighting method at the temporal size NT = 6 and lattice spacing as low as a ≈0.19 fm.
