Dua Lipa, ignoring dad, secures conditions of being in two states (9)

I believe the answer is:

dualities

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

'conditions of being in two states' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'dua lipa ignoring dad secures' is the wordplay.
'ignoring' is a deletion indicator.
'dad' becomes 'pa' (both can mean one's father).
'secures' becomes 'ties' (tying is a kind of securing).
'lipa' with 'pa' taken away is 'li'.
'dua'+'li'+'ties'='DUALITIES'

Can you help me to learn more?
