Yell ... "Gone crazy! May end in study of low temperature physics." (8)

I believe the answer is:

cryogeny

I'm a little stuck... Click here to teach me more about this clue!

'study of low temperature physics' is the definition.
'cryogeny' can be an answer for 'physics' (cryogeny is a kind of physics). I'm not sure about the 'study of low temperature' bit.

'yell gone crazy may end' is the wordplay.
'yell' becomes 'cry' (synonyms).
'crazy' indicates an anagram.
'end' indicates one should take the final letters.
The last letter of 'may' is 'y'.
'gone' anagrammed gives 'ogen'.
'cry'+'ogen'+'y'='CRYOGENY'

'in' acts as a link.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
