IFT Seminar online: https://zoom.us/j/96551192885?pwd=VExJL3pFbER2dUVGRExSNUNZOGhlQT09
Everything should be made as simple as possible, but not simpler. This
classic Einstein's quote summarizes beautifully the spirit of effective
field theories (EFTs), where the measure of simplicity is dictated by the
symmetries of the system. In this talk, I will promote the role and the
power of EFT methods by discussing with you some interesting open questions
such as the difference between liquids and solids, the nature of glassy
materials and the role of periodicity in crystals. I will guide you through
the different theoretical layers, from standard EFT and hydrodynamics to
holographic techniques, emphasizing the leading role of spacetime
symmetries and the wide range of applicability of these methods.
The talk is designed in a colloquium format suitable for all IFT members from
the 1st to 5th floor and it will be my farewell to IFT after these 2 productive
years.
