STOCHASTIC QUANTIZATION AT FINITE CHEMICAL POTENTIAL
 

Summary: STOCHASTIC QUANTIZATION
AT FINITE CHEMICAL POTENTIAL:
SIGN AND SILVER BLAZE PROBLEMS
Gert Aarts
Swansea University
ECT*, March 2009 p.1
OUTLINE
sign problem at finite chemical potential
a revived approach: stochastic quantization
three QCD inspired models
relativistic Bose gas
the Silver Blaze problem is not a problem
ECT*, March 2009 p.2
QCD AT FINITE
SIGN PROBLEM
fermion determinant is complex
[det M()]
= det M(-)
avoid fluctuating sign?
simulations at = 0 or with | det M()|
