[institut] SCL Seminar: Jaksa Vucicevic, Friday, 3 March, 11:00

[Darko Tanaskovic]

Dear colleagues,

You are cordially invited to the SCL seminar of the Center for the Study 
of Complex Systems, which will be held on Friday, 3 March 2017 at 11:00 
in the library reading room “Dr. Dragan Popović" of the Institute of 
Physics Belgrade. The talk entitled

Monte Carlo methods for general lattice fermions

will be given by Dr. Jakša Vučičević (IPhT, CEA Saclay, France; 
Scientific Computing Laboratory, Center for the Study of Complex 
Systems, Institute of Physics Belgrade).

Abstract of the talk:

In the study of various lattice models, Monte Carlo methods have been 
invaluable, and often the only means of reaching controlled and 
non-perturbative solutions. Especially in dynamical mean-field theories, 
a model of a finite-size lattice coupled to an external fermionic bath 
is always solved, sometimes with retarded interactions, and often with 
the need of calculating higher-order correlation functions. In this 
seminar, we will introduce the basic idea of Monte Carlo methods, and 
present how it is applied in the context of fully general lattice 
fermions. The focus will be on the interaction expansion continuous time 
algorithm; we will discuss the common optimization techniques and the 
use of numerical free parameters as a way of controlling the sign 
problem.

Best regards,
Darko Tanasković
