Speaker: Vyshnav Mohan Date: October 16 Time: 13.00 Place: Oddi-203 Title: Complexity, Bulk Reconstruction, and Semiclassical Black Holes Abstract: Quantum computational complexity is an information-theoretic measure that probes the finer details of the Hilbert space of a quantum system. We will study two of its avatars: Krylov complexity and holographic complexity. We will then show […]

Minningarsjóður Hjalta Þórs Ísleifssonar var stofnaður í upphafi árs 2024 af Heiði Hjaltadóttur, móður Hjalta Þórs, en hann féll frá 15. desember 2023. Tilgangur sjóðsins er að hvetja efnilega stærðfræðinema til dáða og gefa þeim tækifæri til framhaldsnáms í stærðfræði. Nemendur sem lokið hafa kröfum fyrstu tveggja námsára í stærðfræði við Háskóla Íslands eiga kost
Speaker: Evangelos Tsolakidis Time and Place: September 16, kl. 13.20, VRII-138 Title: Deformations and Gauge Fields Abstract: Deformations of Quantum Field Theories are an essential tool in our collective attempt to understand the fundamental nature of our universe. They correspond to the so-called interaction terms of a theory, and affect experimentally measurable quantities. In this
