This course gives an introduction to the interaction of mechanical motion with electromagnetic fields in the quantum regime. There are parallels between the quantum descriptions of mechanical resonators, electrical circuits, and light, but each system also has its own unique properties. We will explore how interfacing them can be useful for technological applications and fundamental science.
Learning objective
The course aims to prepare students for performing theoretical and/or experimental research in the fields of quantum acoustics and optomechanics. For example, after this course, students should be able to: - understand and explain current research literature in quantum acoustics and optomechanics - predict and simulate the behavior of mechanical quantum systems using tools such as the QuTiP package in Python - apply concepts discussed in the class toward designing devices and experiments
Content
The focus of this course will be on the properties of and interactions between mechanical and electromagnetic systems in the context of quantum information and technologies. We will only briefly touch upon precision measurement and sensing with optomechanics since it is the topic of another course (227-0653-00L). Some topics that will be covered are: - Mechanical motion and acoustics in solid state materials - Quantum description of motion, electrical circuits, and light. - Different models for quantum interactions: optomechanical, Jaynes-Cummings, etc. - Mechanisms for mechanical coupling to electromagnetic fields: piezoelectricity, electrostriction, radiation pressure, etc. - Coherent interactions vs. dissipative processes: phenomenon and applications in different regimes. - State-of the art electromechanical and optomechanical systems.

Performance assessment information (valid until the course unit is held again)
Repetition only possible after re-enrolling for the course unit.
Additional information on mode of examination
Assessment for the course will take the form of graded homeworks and a seminar-style oral presentation at the end of the semester. Possible topics for the presentation will be distributed around the middle of the semester.
