In the summer of 1925, Heisenberg wrote the paper Über quantentheoretische Umdeutung kinematischer und mechanischer Beziehungen, which laid the foundations of quantum mechanics. For a long time, this paper was considered to be inscrutable. This talk will show how one can make sense both of Heisenberg's formal manipulations and of his philosophical rhetoric, in particular by studying the letters he wrote in months leading up to his breakthrough. A particular emphasis will be placed on how different the theory that Heisenberg originally aimed to construct was from modern quantum mechanics",https://events.umich.edu/event/112846,"Randall Laboratory",3481,"Randall Laboratory",,"brown bag

As a useful low-dimensional model, we consider de Sitter Jackiw-Teitelboim (dS JT) gravity and solve it non-perturbatively in the genus expansion. This amounts to the first non-perturbatively solvable model of de Sitter cosmology. We find that dS JT gravity has an effective string coupling which is pure imaginary, rendering the S-matrix genus expansion Borel resummable. We further establish that dS JT gravity is dual to a formal matrix integral with a negative number of degrees of freedom. More broadly, our analysis unveils new ingredients in the de Sitter holographic dictionary, which may be applicable in more general contexts.",https://events.umich.edu/event/111381,"Randall Laboratory",3481,"Randall Laboratory",,"brown bag
