Construction of Variational Matrix Product States for the Heisenberg Spin-1 Chain
Jintae Kim, Minsoo Kim, Naoki Kawashima +2
We propose a simple variational wave function that captures the correct ground state energy of the spin-1 Heisenberg chain model to within 0.04\%. The wave function is written in t…

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…
