Quantum Fluctuations and Newton-Cartan Geometry for Non-Relativistic de Sitter space
Matthias Harksen, Diego Hidalgo, Watse Sybesma
We study a non-relativistic realisation of two-dimensional de Sitter gravity both from its boundary and bulk description with the goal of learning about de Sitter space and paving…

New Rotating Black Holes in String Theory
Watse Sybesma, Poula Tadros
We present new black hole solutions to the low-energy effective action of string theory. We introduce three- and four-dimensional solutions that are rotating, asymptotically flat,…

Emergence of Krylov complexity through quantum walks: An exploration of the quantum origins of complexity
Dimitrios Patramanis, Watse Sybesma
In this work we study the relationship between quantum random walks on graphs and Krylov/spread complexity. We show that the latter's definition naturally emerges through a canonic…
