Questions:
1. In 1975, X, Hans Georg Dehmelt, Theodor Hansch, and Arthur Schawlow proposed the potential of laser cooling atoms, and X and others validated it by demonstrating it three years later. Name X, who received part of the physics Nobel Prize in 2012.
2. Y was one of many Nobel Prize for physics in 1997 “for the development of methods to cool and trap atoms with laser light”. Thus, he grew to become the primary Nobel Laureate born in an Arab nation. Y is known for growing a variant of laser cooling referred to as ________ cooling. Fill within the clean with the title of a cursed hero in Greek mythology.
3. A easy laser cooling method is named _______ cooling. Here (very merely talking), laser mild is shined on oncoming atoms. The atoms soak up photons from the laser – extra so due to the _______ impact – and decelerate in that path. Fill within the clean with the identical title. Hint: the impact can be skilled when one observes trains.
4. Name the little-known Indian physicist, and a doctoral pupil of C.V. Raman, who found most of the ideas underlying laser cooling. Notably, he found the geometric part – a generalised type of which is at this time referred to as the Berry part, for Michael Berry.
5. Name the system utilized in atomic and molecular physics analysis to lure atoms, together with electrically impartial ones. It does this utilizing laser cooling and a non-uniform magnetic discipline, and might gradual some atoms from greater than ~100 m/s to ~0.1 m/s.
