Prethermalization in one-dimensional quantum many-body systems with confinement
Stefan Birnkammer, Alvise Bastianello, Michael Knap
Unconventional nonequilibrium phases with restricted correlation spreading and slow entanglement growth have been proposed to emerge in systems with confined excitations, calling t…
Critically slow operator dynamics in constrained many-body systems
Johannes Feldmeier, Michael Knap
The far-from-equilibrium dynamics of generic interacting quantum systems is characterized by a handful of universal guiding principles, among them the ballistic spreading of initia…
Emergent Fracton Dynamics in a Non-Planar Dimer Model
Johannes Feldmeier, Frank Pollmann, Michael Knap
We study the late time relaxation dynamics of a pure lattice gauge theory in the form of a dimer model on a bilayer geometry. To this end, we first develop a proper notion o…
Transverse instability and universal decay of spin spiral order in the Heisenberg model
Joaquin F. Rodriguez-Nieva, Alexander Schuckert, Dries Sels +2
We analyze the stability of spin spiral states in the two-dimensional Heisenberg model. Our analysis reveals that the SU(2) symmetric point hosts a dynamic instability that is enab…
Many-body chaos near a thermal phase transition
Alexander Schuckert, Michael Knap
We study many-body chaos in a (2+1)D relativistic scalar field theory at high temperatures in the classical statistical approximation, which captures the quantum critical regime an…
Emergent Glassy Dynamics in a Quantum Dimer Model
Johannes Feldmeier, Frank Pollmann, Michael Knap
We consider the quench dynamics of a two-dimensional quantum dimer model and determine the role of its kinematic constraints. We interpret the non-equilibrium dynamics in terms of…
