HEP Seminar – Fall 2018 – Baggioli

Speaker: Matteo Baggioli

Title: Low energy challenges for high energy physicists – the vibrational modes of matter

Abstract: I will discuss how holographic and effective field theory methods could shed light on important open questions in low energy condensed matter systems. I will focus on the study of the vibrational degrees of freedom, i.e. ”phonons”, in liquids, solids and disordered systems like glasses. Building intuition from the holographic systems I will tackle the problem of the low frequency elastic response in liquids and the universal emergence of the boson peak in ordered crystals and amorphous solids.
