Giacomo Contri - Similarities in the evaporation of saturated solitons and black holes
It was recently suggested that black hole properties, such as the area-law behaviour of the entropy, the existence of an information horizon, thermal evaporation and a long time of information recovery are not specific to gravity. Instead, they are shared by all objects that saturate the quantum field theoretic bound on microstate degeneracy, the so-called "saturons". In this talk I first review the essence of the saturation phenomenon and its connection to black hole physics. Then, I analyse in detail a solitonic saturon appearing in a 1+1 dimensional renormalizable quantum field theory, and calculate its evaporation rate using both a semiclassical Bogoliubov method and a fully quantum description of the bound state. I show how to recover the generic properties of saturation, comment on the correspondence with black hole entropy and radiation, and point out subtle differences between the two evaporation spectra.

Soliton BREakthrough Workshop 2026
A small, informal, and discussion-oriented meeting on (non-)topological solitons and their dynamics which will be held in Opava Czechia from the 7th to the 11th of September 2026. Further details can be found on the workshop's webpage.
New open-source software for numerical soliton simulations (GPU-based, Python)
Paul Leask has just released a GPU based open source soliton solver package in Python which is available on his GitHub page. Currently it is set up to support a range of 2D field theories.
