Is it correct in formal writing to use *while* as a non-temporal adverb?
For instance

> 
> Phenomenon A is generated by XXX, **while** phenomenon B is generated by YYY
> 
> 
> 

Should I rather use :

> 
> Phenomenon A is generated by XXX, **but/and** phenomenon B is generated by YYY
> 
> 
> 

Note that I do not want to imply that A and B are happening at the same time.
