Villa, S. J. Thomson & L. Sanchez-Palencia: <LINK> (This is a companion paper to <LINK> which came out yesterday!) <LINK> In this longer paper, we develop the technique of quench spectroscopy further, and map out the zero temperature phase diagram of disordered bosons at unit filing using both spatially-resolved and momentum-resolved quench spectroscopy. 😅 <LINK> Our main result is that quench spectroscopy provides a new way to explore the zero-temperature phases of quantum matter with what we hope is a simplified experimental protocol, compared to established methods. 😃 Hoping to see some experimental groups try it in the near future! If you missed my thread on yesterday's paper where I outlined the technique in more detail, you can find it here: 👇 <LINK> Please do check out both of our papers - all comments and constructive criticism welcome! 😃",https://arxiv.org/abs/2105.06396,"The question of how the low-energy properties of disordered quantum systems may be connected to exotic localization phenomena at high energy is a key open question in the context of quantum glasses and many-body localization. In arXiv:2105.05774 we have shown that key features of the excitation spectrum of a disordered system can be efficiently probed from out-of-equilibrium dynamics following a quantum quench, providing distinctive signatures of the various phases. Here, we extend this work by providing a more in-depth study of the behavior of the quench spectral functions associated to different observables and investigating an extended parameter regime. We provide a detailed introduction to quench spectroscopy for disordered systems and show how spectral properties can be probed using both local operators and two-point correlation functions. We benchmark the technique using the one-dimensional Bose-Hubbard model in the presence of a random external potential, focusing on the low-lying excitations, and demonstrate that quench spectroscopy can distinguish the Mott insulator, superfluid, and Bose glass phases. We then explicitly reconstruct the zero-temperature phase diagram of the disordered Bose-Hubbard at fixed filling using two independent methods, both experimentally accessible via time-of-flight imaging and quantum gas microscopy respectively, and demonstrate that quench spectroscopy can give valuable insights as to the distribution of rare regions within disordered systems.
