Frustrated mixed-spin ladders: Evidence for a bond order wave phase between rung-singlet and Haldane phases
N. Ahmadi, J. Abouie, R. Haghshenas +1
In frustrated spin ladders the interplay of frustration and correlations leads to the familiar Haldane (H) and rung-singlet (RS) phases. The nature of the transition between these…
Quantum phase diagram of two-dimensional transverse field Ising model: unconstrained tree tensor network and mapping analysis
M. Sadrzadeh, R. Haghshenas, A. Langari
We investigate the ground-state phase diagram of the frustrated transverse field Ising (TFI) model on the checkerboard lattice (CL), which consists of Néel, collinear, quantum para…
Emergence of string-valence bond solid state in the frustrated transverse field Ising model on the square lattice
M. Sadrzadeh, R. Haghshenas, S. S. Jahromi +1
We investigate the ground state nature of the transverse field Ising model on the square lattice at the highly frustrated point . At zero field, the model ha…
Topological phases of the compass ladder model
R. Haghshenas, A. Langari, A. T. Rezakhani
We characterize phases of the compass ladder model by using degenerate perturbation theory, symmetry fractionalization, and numerical techniques. Through degenerate perturbation th…
Quantum phase transition as an interplay of Kitaev and Ising interactions
A. Langari, A. Mohammad-Aghaei, R. Haghshenas
We study the interplay between the Kitaev and Ising interactions on both ladder and two dimensional lattices. We show that the ground state of the Kitaev ladder is a symmetry-prote…
Symmetry fractionalization: Symmetry-protected topological phases of the bond-alternating spin- Heisenberg chain
R. Haghshenas, A. Langari, A. T. Rezakhani
We study different phases of the one-dimensional bond-alternating spin- Heisenberg model by using the symmetry fractionalization mechanism. We employ the infinite matrix-produ…
