Let $A_1$ and $A_2$ be disjoint intervals in an infinite XY chain, with lengths $_1$ and $_2$ and separation $d$, and set $=_1+_2$. Work in the scaling limit $_1,_2,d,t\to\infty$ w…

Boundary conservation-law conjecture. The following statements hold:

Even-charge locality conjecture. The charges $Q_{2j}$ correspond to local conservation laws in the semi-infinite chain. This is a conjecture about the boundary completion of the bu…
