Topological delocalization in the completely disordered two-dimensional quantum walk
János K. Asbóth, Arindam Mallick
We investigate numerically and theoretically the effect of spatial disorder on two-dimensional split-step discrete-time quantum walks with two internal "coin" states. Spatial disor…

Spectral Magnetization Ratchets with Discrete Time Quantum Walks
A. Mallick, M. V. Fistul, P. Kaczynska +1
We predict and theoretically study in detail the ratchet effect for the spectral magnetization of periodic discrete time quantum walks (DTQWs) --- a repetition of a sequence of …

Quantum Simulation of Neutrino Oscillation and Dirac Particle Dynamics in Curved Space-time
Arindam Mallick
Quantum simulation is an important way to study the Dirac particles in a general situation. Discrete quantum walk (DQW), is a powerful quantum simulation scheme, and implementable…
