The Case of Fleeting Orders and Flickering Quotes
Journal of Futures Markets, Volume 46, Issue 4, Page 629-652, April 2026.ABSTRACT The literature controversially discusses the ambiguous motives and driving forces behind quickly cancelled limit orders (fleeting orders), which are characteristic of high‐frequency markets. In particular, manipulative and dysfunctional characteristics are feared. We analyze top‐of‐book fleeting orders—so‐called flickering quotes—and show with

Active digital spoof plasmonics [PDF]
National Science Review, 2019 Abstract Digital coding and digital modulation are the foundation of modern information science. The combination of digital technology with metamaterials provides a powerful scheme for spatial and temporal controls of electromagnetic waves. Such a technique, however, has thus far been limited to the control of free-space light.
