Detection of Chern numbers and entanglement in topological two-species systems through subsystem winding numbers
James de Lisle, Suvabrata De, Emilio Alba +4
Topological invariants, such as the Chern number, characterise topological phases of matter. Here we provide a method to detect Chern numbers in systems with two distinct species o…

Nonreversal and nonrepeating quantum walks
T. J. Proctor, K. E. Barr, B. Hanson +4
We introduce a variation of the discrete time quantum walk, the nonreversal quantum walk, which does not step back onto a position which it has just occupied. This allows us to sim…
