Employing constraints derived from the microscopic theory of strong interaction, we estimate zero-temperature phase structure dense isospin-asymmetric matter with two quark flavors. We find indications that strong-interaction along trajectories relevant for astrophysical applications undergoes a first-order transition color-superconducting to an ungapped quark-matter when density is increased. ...

The effects of nonperturbative configurations at finite temperature are investigated for a real scalar field theory that exhibits a spontaneous symmetry breaking at zero temperature. In l+l dimensions we find a zero temperature phase transition due to kink-antikink pairs. In 3+1 dimensions we calculate the contribution of bubbles that have an interior region of different vacuum in the equilibri...

Here we observe that list coloring in graph theory coincides with the zero-temperature antiferromagnetic Potts model with an external field. We give a list coloring polynomial that equals the partition function in this case. This is analogous to the well-know connection between the chromatic polynomial and the zero-temperature, zero-field, antiferromagnetic Potts model. The subsequent cross fer...
