Collective communication in a transparent world: Phase transitions in a many-body Potts model and social-quantum duality
We consider the Schelling-like social competition reflected in "dynamics of opinions" among groups of agents ("communities") in a highly transparent world. Specifically, we investigate a $q$-state Potts spin system with competing two- and three-body interactions on a complete graph. Agents interact through pairwise repulsion (opposing opinions) between different communities and three-body attraction (shared opinions) within the same community. In the thermodynamic limit, we identify variants of…

Update on the Estlink-2 #subseacable cut last December:
"Finnish authorities [...] have charged the captain and two senior officers of a Russia-linked vessel that damaged undersea cables last year between Finland and Estonia."

Finland charges top officers of Russia-linked vessel that damaged undersea cables
Finnish authorities say they have charged the captain and two senior officers of a Russia-linked vessel that damaged undersea cables last year between Finland and Estonia. Monday's statement says they denied the allegations of aggravated criminal mischief and aggravated interference with communications. Authorities have said the vessel dragged its anchor to damage the Estlink-2 power cable and communication links between Finland and Estonia on Dec. 25. The Kremlin previously denied involvement …

User Perceptions and Attitudes Toward Untraceability in Messaging Platforms
Mainstream messaging platforms offer a variety of features designed to enhance user privacy, such as disappearing messages, password-protected chats, and end-to-end encryption (E2EE), which primarily protect message contents. Beyond contents, the transmission of messages generates metadata that can reveal who communicates with whom, when and how often. In this paper, we study user perceptions of "untraceability", i.e., preventing third parties from tracing who communicates with whom, with the g…

Phase Noise Tolerance for Low-Pilot-Overhead OFDM Terahertz Links Beyond 64-QAM
THz wireless communications have garnered significant attention due to their unprecedented data rates enabled by the abundant untapped spectrum. However, advanced modulation formats beyond 64-QAM remain largely unexplored, as phase errors introduced during up/down-conversion severely limit system performance. Particularly, OFDM transmission is highly susceptible to aggravated ICI induced by phase noise, undermining the orthogonality of subcarriers. While PLLs and pilot-assisted compensation can…
