Supplimentary Materials
Chapter 4 of 12: Optical Pumping
Light can be used to manipulate atomic angular momentum, and can raise electrons from lower energy levels to higher ones. (7 minutes, 52 seconds)
Chapter 1 of 12: A Microscopic Journey
Claude Cohen-Tannoudji discusses how quantum mechanics is essential for understanding the microscopic world. (5 minutes, 3 seconds)
Chapter 2 of 12: Two Views on Light
Light provides not only a source of information, but it also provides a tool for manipulating atoms. (7 minutes, 39 seconds)
Chapter 3 of 12: Dual Personalities
The concept that light exhibits both wave-like and particle-like properties is a central to quantum mechanics. (7 minutes, 40 seconds)
Chapter 4 of 12: Optical Pumping
Light can be used to manipulate atomic angular momentum, and can raise electrons from lower energy levels to higher ones. (7 minutes, 52 seconds)
Chapter 5 of 12: Optical Traps
Cohen-Tannoudji discusses the methods that have been developed using light to trap atoms and freeze them at ultracold temperatures. (5 minutes, 16 seconds)
Chapter 6 of 12: Atomic Clocks
Laser cooling has many useful applications. For instance, atomic clocks have been created that can keep time with extreme precision. (5 minutes, 40 seconds)
Chapter 7 of 12: New Perspectives
Cohen-Tannoudji discusses the manipulation of single atomic particles, macroscopic quantum phenomena and quantum information. (6 minutes, 25 seconds)
Chapter 8 of 12: New States of Matter
Atoms cooled and trapped by lasers can behave very unusually; they can 'condense' into a new form of matter — a Bose-Einstein condensate. (7 minutes, 29 seconds)
Chapter 9 of 12: Conclusions
Cohen-Tannoudji concludes his lecture by showing how the ability to control and manipulate quantum systems has increased considerably over the last four decades. (7 minutes, 41 seconds)
Chapter 10 of 12: Audience Questions, Part 1
Cohen-Tannoudji answers questions on electron spin, thermodynamic equilibrium and polarization. (5 minutes, 36 seconds)
Chapter 11 of 12: Audience Questions, Part 2
Cohen-Tannoudji discusses the difference between qbits and classical bits. (6 minutes, 16 seconds)
Chapter 12 of 12: Audience Questions, Part 3
Cohen-Tannoudji discusses how you can visualize light emitted by a single atom. (3 minutes, 40 seconds)
Description
Claude Cohen-Tannoudji charts the amazing advances made in the last four decades which have enabled us to control and manipulate quantum systems.
