not my area, but I think they're working with 'floquet systems' (the same platform used to build a time crystal) and 'mbl systems' (a kind of quantum system that can be temporarily protected from thermodynamic entropy). I'm reaching, but I think both kinds of systems show extended lifetimes when you drive them externally with a periodic laser.
The Else paper is using two lasers with non-ratio frequencies to extend the lifetime of these systems. The new dumitrescu paper is discretizing that approach by using a fibonacci sequence instead? and somehow this buys them a few more seconds of system coherence?
As far as I understand it, either two incommensurate frequencies or the Fibonacci sequence ABAAB… approach produce similar physics. The Fibonacci sequence is easier to simulate numerically on a (classical) computer because there is a recursive property to it that allows you to jump forward in time in large steps, making it nice for theorists even if the experiments are fairly similar.

I think the Dumitrescu paper is building on work done in Else 2020 https://arxiv.org/abs/1910.03584
