Interference-induced localization in quantum random walk on clean cyclic graph
Jayanth Jayakumar, Sreetama Das, Aditi Sen De +1
We quantitatively differentiate between the spreads of discrete-time quantum and classical random walks on a cyclic graph. Due to the closed nature of any cyclic graph, there is ad…
Multipartite entanglement at dynamical quantum phase transitions with non-uniformly spaced criticalities
Stav Haldar, Saptarshi Roy, Titas Chanda +2
We report dynamical quantum phase transition portrait in the alternating field transverse XY spin chain with Dzyaloshinskii-Moriya interaction by investigating singularities in the…
Inhibition of spreading in quantum random walks due to quenched Poisson-distributed disorder
Sreetama Das, Shiladitya Mal, Aditi Sen De +1
We consider a quantum particle (walker) on a line who coherently chooses to jump to the left or right depending on the result of toss of a quantum coin. The lengths of the jumps ar…
