Keynote 2022#Day3 – Henrik JENSEN – What Happens in the Vicinity of the Critical Point and How Do You Get There?
braincriticality.org
By Henrik Jensen (London, UK). We will briefly recall the description of behaviour near a critical equilibrium phase transition, i.e., when the correlation length diverges to infinity leading to un…
