Quantum metrology in the finite-sample regime - VIRTUAL
Johannes Meyer - Freie Universität Berlin
In quantum metrology, one of the major applications of quantum technologies, the ultimate precision of estimating an unknown parameter is often stated in terms of the Cramér-Rao bound. Yet, the latter is no longer guaranteed to carry an operational meaning in the regime where few measurement samples…
Generalized angular momentum via Wald-Zoupas
Antoine RIGNON-BRET - Aix-Marseille University
In the last years, asymptotic symmetries have regained a lot of interest, and various extensions of the well known BMS group have been considered in the literature. Many charges associated to the diffeomorphisms of the sphere (superboosts and superrotations) have been proposed, but it has not been…
Causality and positivity in causally complex operational probabilistic theories
Lucien Hardy - Perimeter Institute for Theoretical Physics
In the usual operational picture, operations are represented by boxes having inputs and outputs. Further, we usually consider the causally simple case where the inputs are prior to the outputs for each such operation. In this talk (motivated by an attempt to formulate an operational probabilistic…

Gravitational attraction: dynamically enhanced formation of millisecond pulsars in globular clusters
Claire Ye - University of Toronto
A high specific abundance of millisecond radio pulsars has been observed in globular clusters (GCs), motivating theoretical studies of the formation and evolution of these sources through stellar evolution coupled to stellar dynamics. In this talk, I will first demonstrate how we model millisecond…
Long-Range Order on Line Defects in Ising Conformal Field Theories
Ryan Lanzetta - Perimeter Institute for Theoretical Physics
It is well-known that one-dimensional systems at finite temperature, such as the classical Ising model, cannot spontaneously break a discrete symmetry due to the proliferation of domain walls. The validity of this statement rests on a few assumptions, including the spatial locality of interactions…
