Path Integral for Spin-1 Chain in the Fluctuating Matrix Product State Basis
Jintae Kim, Rajarshi Pal, Jin-Hong Park +1
A new method of writing down the path integral for spin-1 Heisenberg antiferromagnetic chain is introduced. In place of the conventional coherent state basis that leads to the non-…

Low-energy dynamics of the Affleck-Kennedy-Lieb-Tasaki model in the one- and two-triplon basis
Jintae Kim, Rajarshi Pal, Jung Hoon Han
The elementary excitation in the antiferromagnetic spin-1 model known as the Affleck-Kennedy-Lieb-Tasaki (AKLT) Hamiltonian has been described alternatively as magnons or kink-like…
