Solvable relaxation in discrete unitary systems: Ruelle-Pollicott resonances and CMV matrices
Urban Duh, Friedrich Hübner, Marko Žnidarič
Leading eigenvalues of the truncated propagator, known as Ruelle-Pollicott (RP) resonances, are an elegant way of addressing the dynamics of unitary many-body systems. We study uni…
Interacting Quantum Symmetric Exclusion Process
Denis Bernard, Friedrich Hübner, Stefano Scopa
We introduce and solve the Interacting Quantum Symmetric Exclusion Process (IQSEP), a family of models describing the stochastic quantum hopping of charged particles along the edge…
Hydrodynamics without Averaging -- a Hard Rods Study
Friedrich Hübner
On the example of the integrable hard rods model we study the quality of the (generalized) hydrodynamic approximation on a single coarse-grained sample. This is opposed to the trad…
Circuits as a simple platform for the emergence of hydrodynamics in deterministic chaotic many-body systems
Sun Woo P. Kim, Friedrich Hübner, Juan P. Garrahan +1
The emergence of hydrodynamics is one of the deepest phenomena in many-body systems. Arguably, the hydrodynamic equations are also the most important tools for predicting large-sca…
Diffusive hydrodynamics from long-range correlations
Friedrich Hübner, Leonardo Biagetti, Jacopo De Nardis +1
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 maxim…
Generalized hydrodynamics of integrable quantum circuits
Friedrich Hübner, Eric Vernier, Lorenzo Piroli
Quantum circuits make it possible to simulate the continuous-time dynamics of a many-body Hamiltonian by implementing discrete Trotter steps of duration . However, when is s…
