Thermal conductivity of anisotropic spin - 1/2 two leg ladder:Green's function approach
Hamed Rezania, Abdollah Langari, Paul H. M. van Loosdrecht +1
We study the thermal transport of a spin-1/2 two leg antiferromagnetic ladder in the direction of legs. The possible effect of spin-orbit coupling and crystalline electric field ar…
Phase transition to spatial Bloch-like oscillation in squeezed photonic lattices
M. Khazaei Nezhad, A. R. Bahrampour, M. Golshani +2
We propose an exactly solvable waveguide lattice incorporating inhomogeneous coupling coefficient. This structure provides a classical analogue to the squeezed number and squeezed…
Ground-state fidelity of the spin-1 Heisenberg chain with single ion anisotropy: quantum renormalization group and exact diagonalization approaches
A. Langari, F. Pollmann, M. Siahatgar
We study the phase diagram of the anisotropic spin-1 Heisenberg chain with single ion anisotropy (D) using a ground-state fidelity approach. The ground-state fidelity and its corre…
Transverse localization in nonlinear photonic lattices with second-order coupling
M. Golshani, A. R. Bahrampour, A. Langari +1
We investigate numerically the effect of long-range interaction on the transverse localization of light. To this end, nonlinear zigzag optical waveguide lattices are applied, which…
