Resolves the same as https://polymarket.com/event/is-the-room-temp-superconductor-real

This market will resolve to "Yes" if the results of the paper titled "The First Room-Temperature Ambient-Pressure Superconductor" (https://arxiv.org/abs/2307.12008) are replicated at least two times by independent researchers unaffiliated with the authors of this paper by December 31, 2023, 11:59 PM ET. Otherwise, this market will resolve to "No".

The resolution source for this market will be a consensus of credible sources and experts verifying the legitimacy of these replications.

If there is ambiguity as to whether replications under consideration for the resolution of this market are credible, this may remain open until July 31, 2024, 11:59 PM ET, to allow for the publication of any replication results in a reputable journal. One such publication will be sufficient to resolve this market to "Yes". If no such paper is published by this delayed resolution time, this market will resolve to "No".

Superconductor Pb$_{10-x}$Cu$_x$(PO$_4$)$_{6O}$ showing levitation at room temperature and atmospheric pressure and mechanism

A material called LK-99, a modified-lead apatite crystal structure with the composition Pb$_{10-x}$Cu$_x$(PO$_4$)$_{6O}$ ($0.9<x<1.1$), has been synthesized using the solid-state method. The material exhibits the Ohmic metal characteristic of Pb(6s1) above its superconducting critical temperature, $…
