✦ Synopsis

Within the reweighting approach, one has the freedom to choose the Monte Carlo action so that it provides a good overlap with the finite-p measure but remains simple to simulate. We explore several choices of action in the regime of small p. Simulating with a finite isospin chemical potential PI = p gives a better overlap t,han the standard choice p = 0: with no computational overhead.

We present results on the QCD phase diagram for small densities without reweighting. Our simulations are performed with an imaginary chemical potential ,LLI for which the fermion determinant is positive. On an 83 x 4 lattice with 2 flavors of staggered quarks, we map out the pseudo-critical temper

We simulate lattice QCD at a finite chemical potential ~1 for isospin (1s) at zero and finite temperatures. At some ~1 = pc QCD has a second order transition with mean-field critical exponents to a state where ( 13) is broken spontaneously by a charged pion condensate. Heating the system with PI > /
