Study of Loschmidt Echo for two-dimensional Kitaev model
Shraddha Sharma, Atanu Rajak
In this paper, we study the Loschmidt Echo (LE) of a two-dimensional Kitaev model residing on a honeycomb lattice which is chosen to be an environment that is coupled globally to a…

Loschmidt echo with a non-equilibrium initial state: early time scaling and enhanced decoherence
Victor Mukherjee, Shraddha Sharma, Amit Dutta
We study the Loschmidt echo (LE) in a central spin model in which a central spin is globally coupled to an environment (E) which is subjected to a small and sudden quench at …

Study of Loschmidt Echo for a qubit coupled to an XY-spin chain environment
Shraddha Sharma, Victor Mukherjee, Amit Dutta
We study the temporal evolution of a central spin-1/2 (qubit) coupled to the environment which is chosen to be a spin-1/2 transverse XY spin chain. We explore the entire phase diag…
