Join us for this week's Mathematics Essex Seminar, Spring Term 2024. Our MESS talks are open to everyone, and offer a great opportunity to meet new people and join in with our community.


Dr Nikolaos Fytas (University of Essex) will present this seminar on Computer simulations in Statistical Physics.


In this talk I will present the basic ideas behind some of the most powerful numerical methods in Statistical Physics used for unravelling the critical behaviour of complex magnetic spin models. These methods are an asset especially for the study of disordered systems which feature a rough free-energy landscape and, when combined with theoretical approaches such as field theory, finite-size scaling, and the renormalisation group, can provide clear-cut answers to longstanding problems in the field. Selected examples of successful application of these methods will also be discussed, mostly focusing on the problem of universality violations in the random-field Ising model but also in the determination of the order of the transition in spin-1 models under the presence of a chemical potential.

How to attend

The seminar will be held in STEM 3.1 at 15:00 on Thursday 22 February. It is open to everyone, including the general public. Please contact Dr Dmitry Savostyanov (d.savostyanov@essex.ac.uk) for further information.
