Pierre-Etienne Wolf

Overview

As a low-temperature physicist, the core of my past and present activities concerns the physics of Helium. Over the years, I have studied the roughening transition of solid Helium 4, the properties of highly spin-polarized liquid Helium 3, atomization processes in liquid helium, and phase transitions of Helium 4 confined in porous media. The common feature of these studies is that they use Helium as a model system for different general physical problems, in fields ranging from statistical and quantum physics to hydrodynamics and soft matter.
