   I don't know what is "bilinear responce". I would be grateful for any help.

   Yes, I saw the term "bilinear response" in a paper and I don't understand it.

   "In a paper". Do you think this is helpful? Maybe you could give a citation and quote the relevant part?

   You can see the term "bilinear response" in the first paragraph of page 3 in the above article.

   It means that it is linear in both ##\delta X_1## and ##\delta X_2##. This is generally used for expressions of the form xy. Also the scalar product ##\langle \phi|\psi \rangle ## is bilinear in ##\psi## and ##\phi^*##.
