Abstract | Superconductivity: thermodynamics, London and Pippard theory; Ginzburg-Landau theory: spontaneous symmetry breaking, flux quantization, type I and II superconductors; microscopic BCS theory: electron-phonon mechanism, Cooper pairing, quasiparticle spectrum and tunneling, Josephson effect, superconducting quantum interference devices (SQUID), brief introduction to unconventional superconductivity. |

Objective | Introduction to the most important concepts of superconductivity both on phenomenological and microscopic level, including experimental and theoretical aspects. |

Content | This lecture course provides an introduction to superconductivity, covering both experimental as well as theoretical aspects. The following topics are covered: Basic phenomena of superconductivity: thermodynamics, electrodynamics, London and Pippard theory; Ginzburg-Landau theory: spontaneous symmetry braking, flux quantization, properties of type I and II superconductors; microscopic BCS theory: electron-phonon mechanism, Cooper pairing, coherent state, quasiparticle spectrum, quasiparticle tunnel, Josephson effects, superconducting quantum interference devices (SQUID), brief extension to unconventional superconductivity. |

Lecture notes | Lecture notes and additional materials are available. |
