Quench Dynamics of Edge States in 2-D Topological Insulator Ribbons
Aavishkar A. Patel, Shraddha Sharma, Amit Dutta
We study the dynamics of edge states of the two dimensional BHZ Hamiltonian in a ribbon geometry following a sudden quench to the quantum critical point separating the topological…

Role of marginality in quantum fidelity and Loschmidt echo: Dirac points in 2-D
Aavishkar A. Patel, Shraddha Sharma, Amit Dutta
We investigate the effect of marginality on the ground state fidelity and Loschmidt echo. For this purpose, we study the above quantities near the quantum critical point (QCP) of t…
