Relativistic physics I

NTMF037

prof. RNDr. Jiří Bičák, DrSc., dr.h.c.,    doc. RNDr. Oldřich Semerák, DSc.

fall term 2021, 4/2 exam/credit

Short syllabus:

More on geometry: tensor densities, covariant divergence, Fermi-Walker transport. Invariant and coordinate features of the Schwarzschild solution, analytic extension of the metric. Pericentre precession and light bending in the Schwarzschild field. Reissner-Nordström solution of the Einstein equations. Kerr and Kerr-Newman solutions of the Einstein equations, Carter equations for electro-geodesic test motion. Gravitational collapse and black holes: black-hole uniqueness theorems, formation of black holes, laws of black-hole (thermo)dynamics, extraction of energy from black holes. Relativistic theory of stellar equilibria: description of a static and spherically symmetric star, equations of stellar equilibria, radial oscillations and stability. Final stages of stellar evolution: degenerate fermion gas, white dwarfs and neutron stars; Chandrasekhar limit. Linearized theory of gravitation, plane gravitational waves.

A follow-up of the basic general-relativity course (NTMF111), mainly suitable for theoretical physicists and astrophysicists at the turn of their bachelor and master studies.

The course continues by NTMF038 – Relativistic physics  II (in spring term).

Time, space, rules:

Thursday 13:10-18:00, with a few breaks, at T1 lecture room (MFF Trója).

In 2021/22, the course is being taught live and in Czech (videos from 2020/21 English run are linked below).

Student seminar talks: one talk per year (per 2 semesters of Relativistic physics) is generally required for credit.
Examinantion in Czech as well as in English can be chosen.
Comments welcome during lecture or via email (oldrich.semerak@mff.cuni.cz).

          ... Jan Došek (14-10)
          ... examined, but not in full detail
      3) Angular momentum (spin) and the Fermi-Walker transport [Bičák, Rudenko, sections 1.5, 1.6, 2.2; also GTR, chapter 18 (up to 18.1)]
          ... Jan Kříž, Róbert Jurčo (04-11)

  • Special message from 25th January (2021):
    I made a mistake in one of the lectures (second part of the semester). I mean quite a serious one, not just a wrong index :-(. Who discovers and explains it will be rewarded somehow (don't know how yet).
