Geometric origin of intrinsic rigidity for extremal horizons
Wojciech Kamiński, Adam Szereszewski
Our work clarifies the origin of enhanced symmetry of near horizon geometries. We relate this property to an existence of specific foliation by non-expanding horizons. The existenc…
Identical, independent quantum weak measurements violate objective realism
Tomasz Rybotycki, Tomasz Białecki, Josep Batle +4
We demonstrate violation of objective realism in quantum world using unconstrained weak measurements. Instead of limited Leggett-Garg approach with artificial bounds on the observe…
Dispersionless Hirota system and hidden symmetries of heavenly equation
Andriy Panasyuk, Adam Szereszewski
In 2021 Konopelchenko, Schief and Szereszewski observed that solutions of 4D dispersionless Hirota system also solve the general heavenly equation describing self-dual vacuum Einst…
Testing time order and Leggett-Garg inequalities with noninvasive measurements on public quantum computers
Tomasz Rybotycki, Tomasz Białecki, Josep Batle +4
We demonstrate the first violation of the Leggett-Garg inequality and time-order noninvariance on public quantum computers using genuine noninvasive measurements. By gathering suff…
Webs, Nijenhuis operators, and heavenly PDEs
Andriy Panasyuk, Adam Szereszewski
In 1989 Mason and Newman proved that there is a 1-1-correspondence between self-dual metrics satisfying Einstein vacuum equation (in complex case or in neutral signature) and pairs…
Self-dual Einstein spaces and the general heavenly equation. Eigenfunctions as coordinates
B. G. Konopelchenko, W. K. Schief, A. Szereszewski
Eigenfunctions are shown to constitute privileged coordinates of self-dual Einstein spaces with the underlying governing equation being revealed as the general heavenly equation. T…
