Course on Modern Condensed Matter

Welcome to the Nordita course page for Modern Condensed Matter.

The course is intended for advanced graduate students. Prerequisites are QM1, QM2.

The essential topics will include: Experimental techniques: neutron scattering, ARPES, optics. We also will discuss collective behavior, transport theory, band structure, quantum phase transitions, magnetism, superconductivity and superfluidity, correlated materials and machine learning and data informatics applied to electronic materials, topological states.

COVID-19 Notice

Important update: because of COVID-19 and shift to online classes, future lectures will be posted. Classes continue as scheduled online via Zoom. Instructors are available for a discussion online. The best times are Monday 15:00-16:00 or email and we will settle the time. Final exam will be in the form of online presentation of research topic with the written report (7-10 pages), see more below.

Registration closed

This course is already running and no more registrations are being accepted.

Grading

Grading: Pass-Fail. Credit: 6 hours, upon agreement with the supervisor.

Important part of the course are essays on research topic, selected in consultations with teachers. We will give 2-3 weeks to prepare the essays and presentation.

For essays: written report ~7-10 pages + ppt (~7 slides) oral presentation (15-20 min) in front of the class.
Home work with the problem set: depending on the module and teacher.
Finals (DATE: Nov 18 2020): essays on selected topics.
