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 کاملTesting Imaginary Vs . Real Chemical Potential in Finite - Temperature Qcd
One suggestion for determining the properties of QCD at finite temperatures and densities is to carry out lattice simulations with an imaginary chemical potential whereby no sign problem arises, and to convert the results to real physical observables only afterwards. We test the practical feasibility of such an approach for a particular class of physical observables, spatial correlation lengths...
متن کاملImaginary-chemical-potential quantum Monte Carlo method for Hubbard molecules.
We generalize the imaginary-chemical-potential quantum Monte Carlo (QMC) method proposed by Dagotto [Phys. Rev. B 41, R811 (1990)] to systems without particle-hole symmetry. The generalized method is tested by comparing the results of the QMC simulations and exact diagonalization on small Hubbard molecules, such as tetrahedron and truncated tetrahedron. Results of the application of the method ...
متن کاملReal and Imaginary Chemical Potential in 2-color Qcd
In this paper we study the finite temperature SU(2) gauge theory with staggered fermions for non-zero imaginary and real chemical potential. The method of analytical continuation of Monte Carlo results from imaginary to real chemical potential is tested by comparison with simulations performed directly for real chemical potential. We discuss the applicability of the method in the different regi...
متن کاملLattice QCD at finite density: imaginary chemical potential
I describe the results for the critical line and the thermodynamics of different phases of QCD which have been obtained by lattice simulations with an imaginary chemical potential. I review motivations and merits of the different strategies – Taylor expansion, Fourier analysis and Pade’ approximants – for analytic continuation from imaginary to real chemical potential. I consider phenomenologic...
