72566 - Introduction to Quantum Optics

Learning outcomes

The student will learn elementary quantum optics and matter-wave interaction theory in order to understand the recent experimental advances in the field of laser-assisted manipulation of atoms, specifically laser cooling and trapping for both fundamental and applied physics.

Course contents

Matter-wave interaction: A e B di Einstein's A and B.

Two levels atom in a classical field: optical Bloch equations, Bloch's vector, rotating wave approximation, Rabi's oscillations, Ramsey's method.

Two levels atom in a quantized field (Jaynes-Cummings' model): Fock's states and coherent states, spontaneous decay, micromaser.

dressed atom: energy levels, fluorescence spectrum.

Laser cooling: Doppler cooling, Doppler limit, elements of sub-Doppler cooling.

Ion traps: RF traps (Paul), static traps (Penning).

Atom traps: magneto-optical traps, magnetic traps (Quadrupole,Joffe,Time Orbiting Potential), optical traps, optical lattices.

Some special lasers: ultrastable CW lasers, optical combs, measurement of optical frequencies.

Some notions on: evaporative cooling, reaching quantum degeneracy, optical clocks, atom interferometry, quantum computers

Readings/Bibliography

- Notes and slides from the teacher. Check on iol.

Teaching methods

Lectures and assigned readings and discussion of scientific papers.

Assessment methods

The knowledge of the basic facts of atoms-radiation interaction will be verified with oral questions and/or with the request to the student to prepare a short seminar on arguments treated in the course.

Students with learning disorders and\or temporary or permanent disabilities: please, contact the office responsible as soon as possible so that they can propose acceptable adjustments. The request for adaptation must be submitted in advance (15 days before the exam date) to the lecturer, who will assess the appropriateness of the adjustments, taking into account the teaching objectives.
