OVERVIEW

The course provides an introduction to Monte Carlo simulation techniques for condensed matter and fundamental interactions physics.

AIMS AND CONTENT

LEARNING OUTCOMES

The course aims at providing an introduction to Monte Carlo simulation techniques

   applied to condended matter and fundamental interations physics.

AIMS AND LEARNING OUTCOMES

The course aims at providing the basic knowledge of Monte Carlo simulation techniques with application to condended matter and fundamental interactions physics.

For condensed matter physics the learning outcomes are:

    - Markov chain simulation (Metropolis algorithm)

    - Simulation of phase transition in reticulated gas

    - Continuos-time Monte Carlo for equilibrium and non-equilibrium transitions

    - Simulation of aggregate creation. Fractals.

For the physics of fundamental interactions the learning outcomes are:

    - Simulation of the transport of particles in matter

    - Simulation of the interaction and decay of particles in Lorentz-invariant phase space

    - Parametric simulation of a detector

    - Simulation of experiments (past and present)

 

PREREQUISITES

LESSONS

TEACHING METHODS

Theoretical lectures and practical exercitations 

LESSONS START

The teaching will take place in the second semester.

EXAMS

EXAM DESCRIPTION

The oral exam consists in the discussion of an original essay and questions on the course program.

ASSESSMENT METHODS

The original essay consists in the development of a program which, applying concepts and techniques acquired in the course, solves a physical problem.

The final score will take into account the results obtained, their presentation and answers to general questions.
