Avoiding the boson sign problem at finite chemical potential
The usual path integral formulation for scalar particles at finite density involves a sign problem, making numerical simulation impractical. We present alternative methods free of this difficulty. We apply these approaches to |φ | 4 theory in 2 + 1 dimensions, presenting preliminary numerical results for physical quantities in the vicinity of the phase transition in the T − µ plane.
متن کاملThe density of states method at non - zero chemical potential
We study the QCD phase diagram by first principle lattice calculations at so far unreached high densities. For this purpose we employ the density of states method. Unimproved staggered fermions, which describe four quark flavors in the continuum are used in this analysis. Though the method is quite expensive, small lattices show an indication for a triple-point connecting three different phases...
متن کاملA Sign-changing Solution for a Superlinear Dirichlet Problem with a Reaction Term Nonzero at Zero
In previous joint work with A. Castro and J. Cossio (See 5]), it was shown that a superlinear boundary value problem has at least 3 nontrivial solutions, one of which changes sign exactly-once. In this paper we provide an analogous result when the nonlinearity does not pass through the origin; this case includes the so-called semiposi-tone case, i.e., where the nonlinearity is negative at zero....
