We study the effect of SU (3) flavor breaking on high density quark matter. We discuss, in particular, the effect a non-zero electron chemical potential and a finite strange quark mass. We argue that these perturbations trigger pion or kaon condensation. The critical chemical potential behaves as µ e ∼ √ mm s ∆/p F and the critical strange quark mass as m s ∼ m 1/3 ∆ 2/3 , where m is the light ...

We prove that the spectral gap of the Swendsen-Wang process for the Potts model on graphs with bounded degree is bounded from below by some constant times the spectral gap of any single-spin dynamics. This implies rapid mixing for the two-dimensional Potts model at all temperatures above the critical one, as well as rapid mixing at the critical temperature for the Ising model. After this we int...

We argue that these perturbations trigger pion or kaon condensation. The critical chemical potential behaves as μe ∼ √ mms∆/pF and the critical strange quark mass as ms ∼ m1/3∆2/3, where m is the light quark mass...

We investigate the entanglement spectrum near criticality in finite quantum spin chains. Using finite size scaling we show that when approaching a quantum phase transition, the Schmidt gap, i.e., the difference between the two largest eigenvalues of the reduced density matrix λ(1), λ(2), signals the critical point and scales with universal critical exponents related to the relevant operators of...
