Interconnections between equilibrium topology and dynamical quantum phase transitions in a linearly ramped Haldane model
Utso Bhattacharya, Amit Dutta
We study the behavior of Fisher Zeros (FZs) and dynamical quantum phase transitions (DQPTs) for a linearly ramped Haldane model occurring in the subsequent temporal evolution of th…
Quenching in Chern insulators with satellite Dirac points: The fate of edge states
Utso Bhattacharya, Joanna Hutchinson, Amit Dutta
We perform a sudden quench on the Haldane model with long range interactions, more specifically generalising to the next to next nearest neighbour hopping, referred to as the …
Generation of concurrence between two qubits locally coupled to a one dimensional spin chain
Tanay Nag, Amit Dutta
We consider a generalized central spin model, consisting of two central qubits and an environmental spin chain (with periodic boundary condition) to which these central qubits are…
Effects of periodic kicking on dispersion and wave packet dynamics in graphene
Adhip Agarwala, Utso Bhattacharya, Amit Dutta +1
We study the effects of -function periodic kicks on the Floquet energy-momentum dispersion in graphene. We find that a rich variety of dispersions can appear depending on the pa…
Tuning the presence of dynamical phase transitions in a generalized spin chain
Uma Divakaran, Shraddha Sharma, Amit Dutta
We study an integrable spin chain with three spin interactions and the staggered field () while the latter is quenched either slowly (in a linear fashion in time () as …
Slow quenches in a quantum Ising chain; dynamical phase transitions and topology
Shraddha Sharma, Uma Divakaran, Anatoli Polkovnikov +1
We study the slow quenching dynamics (characterized by an inverse rate, ) of a one-dimensional transverse Ising chain with nearest neighbor ferromagentic interactions acros…
