Coherence controls the visibility of frozen disorder in an open quantum chain
S. Y. Li, M. H. Yu, X. Z. Zhang
A Gaussian position distribution need not imply that frozen disorder is irrelevant. We study a resonant quantum chain where neighboring sites couple with opposite signs to auxiliar…

Detector Placement Relaxes Efficiency Requirements for Detecting a Weak Coherent Link
M. H. Yu, S. Y. Li, X. Z. Zhang
A weak coherent link can produce unusually early arrivals without changing stationary count rates. Missed jumps along routes available without the link can produce similar records,…
