From kagome antiferromagnets to self-assembly: anisotropic hierarchy in dense and dilute systems Andrey Zelenskiy (LPTMS)   Geometric frustration arises when interactions favour local configurations that are incompatible with the global geometry of the system. To alleviate frustration, many systems adopt locally suboptimal arrangements, often leading to the emergence of complex structures and patterns. In this […]

Overlaps after a boundary quantum quench in the integrable XXZ spin chain Charbel Abetian   The aim of this thesis is to provide an exact analytical approach for computing overlaps between eigenstates of the open XXZ chain before and after a boundary quench, that is, an abrupt change of one of the boundary magnetic fields.

Soliton gas description of modulational instability Thibault Congy (Northumbria University, Newcastle, UK)   Soliton gases are infinite random ensembles of interacting solitons whose large-scale dynamics are governed by the elementary two-soliton collisions. By applying the spectral theory of soliton gases to the focusing nonlinear Schrödinger equation (fNLSE), we can describe the statistically stationary and spatially
