dc.description
Generalized Hydro Dynamics (GHD) is a novel, very powerful tool to describe 1d systems. After a very brief
introduction, I will first present a way to extend GHD to the dimensional cross over regime [1] and highlight the experimental tests of standard and extended GHD. In the second part of my talk, I will highlight how GHD can give us a much-improved understanding of the excitations and their decay/dephasing in a 1d Bose gas, and thereby highlighting the relationship between many-body interactions and dimensionality. In our experiments we prepare a single mode of excitations and watch it decay. We find that the decay of the excitations is perfectly described with GHD and 1D behaviour can extend deep into the three-dimensional (3D) crossover. Our observations demonstrate that the fundamental excitations are not phonons but are rapidities assuming fermionic statistics, despite the gas being purely bosonic [2]. The rapid damping of phonons can 1d can be understood as the dephasing the rapidities.
