Loschmidt echo of local dynamical processes in integrable and non integrable spin chains
Saikat Sur, V. Subrahmanyam
The Loschmidt echo is investigated to track the effect of the local QDP. It is also quite sensitive to whether the background dynamics is integrable or not. For the integrable case…

Quantum correlations and entanglement in a Kitaev-type spin chain
Vimalesh Kumar Vimal, V. Subrahmanyam
The entanglement and quantum correlation measures have been investigated for the ground state of a spin chain with a Kitaev-type exchange interactions on alternating bonds, along w…

Interference of the signal from a local dynamical process with the quantum state propagation in spin chains
Saikat Sur, V. Subrahmanyam
The effect of a local instantaneous quantum dynamical process (QDP), either unitary or non-unitary, on the quantum state transfer through a unitary Hamiltonian evolution is investi…
