36. Current status and perspectives of complex Langevin calculations in finite density QCD

Prof. Jun Nishimura (KEK)

24/06/2019, 09:00

Invited talk

Monte Carlo studies of finite density QCD is difficult due to the notorious sign problem. As a promising approach that can avoid this problem, the complex Langevin method has been attracting attention. In particular, a practical criterion for correct convergence has been proposed, and it is found to be satisfied in certain parameter regions of finite density QCD. In this talk I will summarize...

49. Complex Langevin applied to chiral random matrix model in T-mu plane

Dr Hirotsugu Fujii (U Tokyo)

Oral talk

We examine the $T-\mu$ phase diagram in the chiral random matrix model in $T-\mu$ plane by checking the correctness condition, i.e., the tail behavior of the ensemble distribution, with varying the matrix size and other model parameters.

61. Complex Langevin Simulations: Reliability and applications to full QCD at non-zero density

Mr Manuel Scherzer (Institute for theoretical Physics, Heidelberg University)

Oral talk

M. Scherzer, E. Seiler, D. Sexty and I.-O. Stamatescu Complex Langevin (Equation) is a well defined method providing a general instrument for ab initio, approximation free studies of realistic lattice models even for complex action. The latter include full QCD at finite density and CLE appears as the only method presently applied in this context. The complexification of the variable space...
