International Internship Program
Max Planck Institute of Quantum Optics About: MPQ is a research facility of the Max Planck Society, dedicated to basic research on the interaction of light and matter under extreme conditions. It consists of several sub divisions (Laser Spectroscopy, Quantum Dynamics, Attosecond and High-Field Physics, Theory, and the division of Quantum Many Body Systems) and several independent research groups, with a total of more than 200 scientists. The stimulating research environment at MPQ results from fruitful collaboration and know-how exchange of the different groups and divisions, making it one of the world-leading research institutions in this field.
Intern Responsibilities: IIP interns will work on one of the following projects:
Projects in Prof. Cirac’s group (Theory): Since 2001 Prof. Dr. J. I. Cirac is Director at the MPQ and head of the Theory division. He has made contributions to quantum many-body physics, information and optics and is an expert in the field of quantum information and quantum computation.
Project 1: Dissipative quantum systems: The IIP intern will apply the numerical algorithms developed in our division to the study of dissipative quantum systems. In particular, different spin chains may be considered. The tasks may include particularizing the algorithm for the chosen problem, designing and performing the numerical study, and analyzing the results.
Project 2: Study of topological phases and phase transitions using tensor networks - The IIP intern will apply tensor network algorithms to the study of topological phases and their excitations. This can in particular include models obtained by adding fields to existing models, and the investigation of the topological phase transition between these models. The student will learn basics of topologically ordered phases, as well as the use of tensor network methods, in particular Matrix Product States (MPS) and Projected Entangled Pair States (PEPS). This project will require a combination of analytical and numerical skills.
Project 3: Computational complexity of physical problems - Computational complexity addresses the difficulty of physical problems. In this project, the student will study how to relate existing complexity results, in particular for the computation of the ground state energy to polynomial accuracy, with physically relevant problems such as the computation of correlation functions, expectation values of local observables, or response functions. This project is very mathematically oriented, as it crucially depends on rigorous error bounds for all approximations used.
Projects in Prof. Bloch’s group (Quantum Many-Body systems): Since 2008, Prof. Immanuel Bloch is Scientific Director of the Quantum Many-Body Systems division at MPQ. With his research, Immanuel Bloch has opened a new and interdisciplinary research field at the interface of quantum physics, quantum information science, atomic- molecular- and condensed matter physics. With the help of ultracold atoms in optical lattices, the vision of physics Nobel prize winner Richard Feynman, i.e. a quantum simulator for studying complex quantum matter, has become reality today.
Project 1: Setup of diode laser systems for laser cooling & trapping - The IIP interns will learn how to build a diode laser systems including spectroscopy and frequency control that will later be used for laser cooling and trapping of ultracold atoms. The students will learn the basics of frequency control of a laser system, including the control electronics and feedback system. This also includes fundamentals of laser optics and optical modulation techniques.
Project 2: Light intensity control system - The IIP intern will learn the basics of light detection, and optical modulators to implement a feedback control system for optical power stabilization used in optical dipole traps for ultra cold atoms. Basic signal analysis as well as some electronics techniques will be used to explore quantum mechanical limits in optical power detection and optimal feedback control.
Qualifications: IIP candidates with interests in quantum physics, quantum information, Many-Body Theory, and elementary atomic physics are encouraged to apply. Basic computer programming skills are required. Upper level physics courses are strongly recommended.
