Difference between vacuum and pseudovacuum vector?

In my case the ground state of a system is the vacuum vector and by letting operators act on that vacuum vector magnons are generated.
Since i've read quite often about a pseudovacuum vector (in other sources, for other systems) i'd like to know, what's the difference.

this is relevant but "we have introduced elements, called "vacuums" to consider the state vectors and the configuration spaces within the world of extended algebra of calculus with various expressions. We have found several strange elements, called polar elements, and an extended notions of vacuums, which were called pseudo-vacuums in our paper. These are not established notions in mathematical physics, but we are thinking that these must propose new frontier for mathematical physics"
