“…the spin-1/2 Heisenberg XXZ chain. Third, our framework is readily generalized to quench dynamics [115] by combining it with the quench action approach [89,90]. Here the novel feature is that the spectral sum involves "overlaps" that multiply the form factors.…”

“…We will call η this pointlike interaction. Depending on the regularization, this η potential can act like an infinite wall for bosons [14,25] or be transparent [28].…”

“…In higher dimensions the definition and regularization of the δ potential is more involved [9][10][11]. But in 1D there also exist other pointlike interactions that find applications and that require a more involved functional form and scaling [12][13][14].…”
