Fidelity susceptibility and Loschmidt echo for generic paths in a three spin interacting transverse Ising model
Atanu Rajak, Uma Divakaran
We study the effect of presence of different types of critical points such as ordinary critical point, multicritical point and quasicritical point along different paths on the Fide…

The three site interacting spin chain in staggered field: Fidelity vs Loschmidt echo
Uma Divakaran
We study the the ground state fidelity and the ground state Loschmidt echo of a three site interacting XX chain in presence of a staggered field which exhibits special types of qua…
