A Subsystem Ginzburg-Landau and SPT Orders Co-existing on a Graph
Jintae Kim, Hyun-Yong Lee, Jung Hoon Han
We analyze a model demonstrating the co-existence of subsystem symmetry breaking (SSB) and symmetry-protected topological (SPT) order, or subsystem LSPT order for short. Its mathem…
Matrix Product Wave Function of the Ground State and Elementary Excitation in the Spin-1/2 Chain
Jintae Kim, Minsoo Kim, Pramod Padmanabhan +2
We present a variational matrix product state (vMPS) for the ground state of the spin-1/2 Heisenberg model. The MPS effectively organizes the various dimer configurations, in faith…
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…
Proposal of a spin-one chain model with competing dimer and trimer interactions
Yun-Tak Oh, Hosho Katsura, Hyunyong Lee +1
A new kind of spin-1 chain Hamiltonian consisting of competing dimer and trimer projection operators is proposed. As the relative strengths and signs of the interactions are varied…
