The module will be supplemented by the module "Ultracold Quantum Gases 2" (PH2125) in the next semester.

Learning Outcome

After successful completion of the module the students are able to:

  • understand various models of the atom-light interaction and can apply them in different contexts
  • analyze the limitations of important techniques for cooling and trapping of ultracold gases
  • understand the basics of Bose-Einstein condensation

Preconditions

Basic knowledge in quantum mechanics (PH0007), atomic physics (PH0016), electrodynamics (PH0006), and statistical physics (PH0008)

Learning and Teaching Methods

The module consists of a lecture and exercise classes. In the thematically structured lecture the learning content is presented. With cross references between different topics, the concepts relevant for the covered topics are explained. In scientific discussions the students are involved to stimulate their analytic intellectual strength. Self-study of textbooks, review articles, and original literature, as e.g. referenced in the lectures notes provided, is an important part of the student’s learning process.

In the exercises the learning content is deepened using problem examples. Thus the students are able to apply and explain the learned physics knowledge independently.

Module Exam

Description of exams and course work

There will be an oral exam of 25 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested exemplarily at least to the given cognition level using comprehension questions and sample calculations.

For example an assignment in the exam might be:

  • How does the temperature limit of Doppler cooling come about?
  • How does a magneto-optical trap work?
  • Why are Majorana spin-flips a problem in magnetic traps and how can they be avoided?

Participation in the exercise classes is strongly recommended since the exercises prepare for the problems of the exam and rehearse the specific competencies.

Remarks on associated module exams

The exam for this module can be taken together with the exam to the associated follow-up module PH2125: Ultra Cold Quantum Gases 2 / Ultrakalte Quantengase 2 after the follwoing semester. In this case you need to register for both exams in the following semester.

Exam Repetition

The exam may be repeated at the end of the semester. There is a possibility to take the exam in the following semester.

Current exam dates

Currently TUMonline lists the following exam dates. In addition to the general information above please refer to the current information given during the course.
