The Department of Physics is delighted to welcome Dr Alessandro Principi (University of Manchester) to give the second Physics Department Colloquium of Semester 2 2023/24. Please join us to listen to Dr Alessandro Principi's seminar titled 'Viscous fluids in solid state systems: a tale of interacting electrons'.
A reception will be held directly after the seminar, where tea and coffee will be provided.
The seminar is open to anyone from the university, students are encouraged to attend.
Viscous fluids in solid state systems: a tale of interacting electrons
Strong interactions are at the origin of emergent phenomena like magnetism and superconductivity which already impact our everyday life, or could change it forever opening a whole new era. While the physics of these equilibrium phases has been studied for quite some time, the impact of interactions (in particular electron-electron interactions) on non-equilibrium properties is much less understood. Notwithstanding the importance of new transport regimes such as many-body localisation, in this colloquium I will focus on the impact of interactions on normal Fermi liquids. These conventional conducting materials typically exhibit either diffusive or ballistic charge transport. However, when electron-electron interactions dominate, a “hydrodynamic” regime emerges. Under these conditions, electrons can behave as a viscous liquid and exhibit hydrodynamic phenomena similar to classical liquids. In this colloquium I will review the history of this field, old and modern theories of hydrodynamic transport in clean materials, and more recent experiments.
