The Heisenberg spin chain is a canonical integrable model. As such, it features stable
ballistically propagating quasiparticles, but spin transport is subballistic at any nonzero …

Universality is a powerful concept, which enables making qualitative and quantitative
predictions in systems with extensively many degrees of freedom. It finds realizations in …

Understanding how hydrodynamic behaviour emerges from the unitary evolution of the
many-particle Schrödinger equation is a central goal of non-equilibrium statistical …

Scale invariance and self-similarity in physics provide a unified framework for classifying
phases of matter and dynamical properties near equilibrium in both classical and quantum …

Understanding universal aspects of quantum dynamics is an unresolved problem in
statistical mechanics. In particular, the spin dynamics of the one-dimensional Heisenberg …

Finite temperature spin transport in integrable isotropic spin chains is known to be
superdiffusive, with dynamical spin correlations that are conjectured to fall into the Kardar …

In thermal equilibrium the dynamics of phase transitions is largely controlled by fluctuation-
dissipation relations: On the one hand, friction suppresses fluctuations, while on the other …

We investigate the impact of nonreciprocity on universality and critical phenomena in open
quantum interacting many-body systems. Nonreciprocal open quantum systems often have …

We develop a comprehensive theoretical model for the interaction strength between a pair of
exciton polaritons in microcavity devices. Ab initio numerical calculations for dipolar …

Dispersion engineering is a powerful and versatile tool that can vary the speed of light
signals and induce negative-mass effects in the dynamics of particles and quasiparticles …
