Irakasgaiaren azalpena eta testuingurua
This course is foundational for later scientific development in the quantum domain. The main object of study are fields, as distinct from particles: the magnitudes of interest are functions of space and time, and not simply of time.In this course you will have a first introduction to how fields can be considered in the quantum regime, on the crucial conceptual new insights required for a first understanding of the new physical phenomena at hand, and to the vocabulary and simpler techniques of QFT.
The main prerequisites are those common to the Master’s programme, namely a strong background in physics and mathematics, with special empha- sis in having been exposed as an undergraduate to Quantum Physics, as applied to the description of atoms, molecules and solid state physics. Some fa- miliarity with classical fields is also expected, in particular with regard to basic electromagnetic the- ory up to Maxwell’s equations and the wave equation. The basic mathematical toolbox of physics is taken for granted (linear algebra, calculus, differential equations up to Fourier analysis and separation of variables for PDEs, complex analysis, basic probability).
