Revivals in One-dimensional Quantum Walks with a Time and Spin-dependent Phase Shift
Muhammad Sajid, Qurat ul Ain, Hanifa Qureshi +1
We investigate the role of a time and spin-dependent phase shift on the evolution of one-dimensional discrete-time quantum walks. By employing Floquet engineering, a time and spin-…

One-Dimensional Quantum Walks with a Position-Dependent Coin
Rashid Ahmad, Uzma Sajjad, Muhammad Sajid
We investigate the evolution of a discrete-time one-dimensional quantum walk driven by a position-dependent coin. The rotation angle which depends upon the position of a quantum pa…

Quantum renormalization group of XY model in two dimensions
M. Usman, Asif Ilyas, Khalid Khan
We investigate entanglement and quantum phase transition (QPT) in a two-dimensional Heisenberg anisotropic spin-1/2 XY model, using quantum renormalization group method (QRG) on a…
