Gravity in Quantum Phenomena

• By Jonny Dadras
• Dedicated to Yuri Kamyshkov

2
How does Gravity enter Schrodinger
What says Ehrenfest?
But Freely falling particles had been observed.
3
Gravitys Weakness

• We know gravity is weak but, how weak?
• What is the Bohr Radius for a gravitationally
  bound neutron and electron?

4
An Interesting Neutron Experiment

• The basic picture of the Colella, Overhauser, and
  Werner (COW) set-up

5
COW - Tipping

• Splitting Neutrons

6
What Comes Out of the COW?

• Results of the first data run from 1975

7
Other Things to Consider

• Mathematical details

8
Yet More Math the Sagnac Effect
9
Current Status of COWs

• Has the experiment been reproduced?
• Has it been improved?

10
Why Is This Interesting?

• What is the sacred COW really? (Mannheim)
• Neutrinos and COWs
