We calculate the dynamical spin structure factor of the generalized spin-1/2 compass spin
chain using the density matrix renormalization group. The model, also known as the twisted …

We study the ground state of the 1D Kitaev-Heisenberg (KH) model using the density-matrix

We investigate Majorana modes in a quantum spin chain with bond-dependent exchange
interactions by studying its dynamics. Specifically, we consider two-time correlations for the …

We show that gapped critical environment could remarkably prevent an enhanced decay of
decoherence factor and quantum correlations at the critical point, which is non-trivially …

We study the magnetic behaviors of a spin-1/2 quantum compass chain (QCC) in a
