Meet other DPhils in a relaxed environment for a coffee and a chat. No booking needed.

The sessions aim to provide a space for DPhil students to meet others informally over the summer vacation, to discuss shared experiences of undertaking a DPhil at Oxford, and to help the University Counselling Service for DPhil students, by identifying common themes and topics for a series of potential term time workshops.

Join us at Oxford Botanic Garden for a relaxing guided tour with Wellbeing Outreach Officer, Dr Rodger Caseby and Education Officer, Dr Lauren Baker.

Journey through the garden's 400 year long history, learning about its original role as a medicinal garden and its transition through to modern day, with a seasonal focus on the Merton Borders. Bring your University card for free Garden entry – we look forward to seeing you soon.

Level repulsion and the Floquet quantum Ising model beyond integrability

Felix von Oppen
(Freie Universität Berlin)
Abstract

Motivated by a recent experiment on a superconducting quantum
information processor, I will discuss the Floquet quantum Ising model in
the presence of integrability- and symmetry-breaking random fields. The
talk will focus on the relation between boundary spin correlations,
spectral pairings, and effects of the random fields. If time permits, I
will also touch upon self-similarity in the dynamic phase diagram of
Fibonacci-driven quantum Ising models.

Simultaneous extreme values of zeta and L-functions

Winston Heap
(Max Planck Institute Bonn)
Abstract
I will discuss a recent joint work with Junxian Li which examines joint distributional properties of L-functions, in particular, their extreme values. Here, it is not clear if the analogy with random matrix theory persists, although I will discuss some speculations. Using a modification of the resonance method we demonstrate the simultaneous occurrence of extreme values of L-functions on the critical line. The method extends to other families and can be used to show both simultaneous large and small values.
