"Locating the critical point in finite systems”


címmel tartandó szemináriumára.


Kivonat:



In a finite system no genuine critical behavior can be observed, which 
makes the identification of an infinite-volume critical point from 
finite-size calculations a highly nontrivial task. We investigate 
several methods for locating criticality at finite sizes based on 
conserved-charge fluctuations and the distribution of the Lee–Yang zeros 
across different volumes. These methods are tested within a mean-field 
effective model of QCD matter that reproduces finite-size effects and 
finite-size scaling, while exhibiting a critical point in the 
thermodynamic limit. We also show that a careful treatment of 
corrections from irrelevant operators is crucial for the accurate 
determination of the critical point.
