Abstract Quantum processes of inherent dynamical nature, such as quantum walks, defy a description in terms an equilibrium statistical physics ensemble. Until now, identifying the general principles behind underlying unitary dynamics has remained key challenge. Here, we show and experimentally observe that split-step walks admit characterization topological order parameter (DTOP). This integer-quantized DTOP measures, at given time, winding geometric phase accumulated by wavefunction during...
Entanglement and the wave function description are two of core concepts that make quantum mechanics such a unique theory. A method to directly measure function, using weak values, was demonstrated by Lundeen et al. [Nature 474, 188 (2011)]. However, it is not applicable scenario disjoint systems, where nonlocal entanglement can be crucial element, since requires obtaining values observables. Here, for first time, we propose bipartite system, modular values. The experimentally implemented...

Specifically, we investigate manifestation these phenomena when material is exposed off-resonant sublattice Using Kubo formula, derive...
