Ornstein-Zernike theory for lattice spin models, an overview of the construction

Vortrag von Sébastien Ott

Datum: 14.11.18   Zeit: 17.15 - 18.15   Raum: ETH HG G 43

I will briefly present the original idea of Ornstein and Zernike for obtaining sharp control over two point functions. Then, I will describe a general strategy to implement this idea in lattice spin models, highlighting the robust parts of the analysis and the ones that require model-specific arguments. I will finish with a quick survey of existing results in the field and open questions.
