The sine-Gordon model captures the low-energy effective dynamics of a wealth of one-
dimensional quantum systems, stimulating the experimental efforts in building a versatile …

The question of macroscopic occupation and the spontaneous emergence of coherence for
exciton ensembles has gained renewed attention due to the rise of van der Waals …

Conventional hydrodynamics describes systems with few long-lived excitations. In one
dimension, however, many experimentally relevant systems feature a large number of long …

It is widely accepted that local subsystems in isolated integrable quantum systems
equilibrate to generalized Gibbs ensembles. Here, we identify a particular class of initial …

Abstract “Generalized Hydrodynamics”(GHD) stands for a model that describes one-
dimensional integrable systems in quantum physics, such as ultra-cold atoms or spin chains …

The classical Landau-Lifshitz equation—the simplest model of a ferromagnet—provides an
archetypal example for studying transport phenomena. In one-spatial dimension …

In the hydrodynamic theory, the non-equilibrium dynamics of a many-body system is
approximated, at large scales of space and time, by irreversible relaxation to local entropy …

Integrable systems offer rare examples of solvable many-body problems in the quantum
world. Because of the fine-tuned structure, their realization in nature and experiment is never …

One-dimensional Mott insulators can be described using the sine-Gordon model, an
integrable quantum field theory that provides the low-energy effective description of several …

Motivated by recent experiments, we investigate the Lieb-Liniger gas initially prepared in an
out-of-equilibrium state that is Gaussian in terms of the phonons, namely whose density …
