Simulating QCD at finite density
Philippe de Forcrand
In this review, I recall the nature and the inevitability of the "sign problem" which plagues attempts to simulate lattice QCD at finite baryon density. I present the main approach…
Constraining the QCD phase diagram by tricritical lines at imaginary chemical potential
Philippe de Forcrand, Owe Philipsen
We present unambiguous evidence from lattice simulations of QCD with three degenerate quark species for two tricritical points in the (T,m) phase diagram at fixed imaginary μ/T=iπ/…
The phase diagram of Yang-Mills theory with a compact extra dimension
Philippe de Forcrand, Aleksi Kurkela, Marco Panero
We present a non-perturbative study of the phase diagram of SU(2) Yang-Mills theory in a five-dimensional spacetime with a compact extra dimension. The non-renormalizable theory is…
Equation of State at Finite Density from Imaginary Chemical Potential
Tetsuya Takaishi, Philippe de Forcrand, Atsushi Nakamura
We perform two flavor QCD simulations with an imaginary chemical potential and measure derivatives of the pressure up to 4th order as a function of the imaginary chemical potential…
